Rev9 Coilovers – Features and Specs Review

Rev9 Coilovers are the latest coilover to hit the market that offer a ton of features and good specs and are a great value. Some would call them “cheap coilovers”, but many of our customers have bought these and simply loved them and the value they provide. We decided to take a deep dive into these Rev9 Coilovers and review their features and specs to see if they make sense to you.

Rev9 Coilovers come in two flavors – Hyper Street Basic and Hyper Street II. Below we’ll review the specs of each:

The Rev9 Hyper Street Basic Coilovers are their most entry level, and have some prices starting at around $364 shipped. These for the most part do not come with new top hats (you need to reuse your own), but unlike other entry level coilovers, these come with adjustable shocks. You can set the dampening on these 32 different ways from ultra soft to ultra firm to dial in just the right ride and handling you prefer.

The Rev9 Hyper Basic Coilovers also come with spanner wrenches to make height adjustments easy.

These coilovers give you the ability to set your ride height roughly 1″ lower than stock up to about 3″ lower. Rev9 doesn’t release exact specs on these, but this has been a pretty accurate ball park.

In summary, our Rev9 Coilovers Review of these specs and features make them one of the most value packed coilovers on the market. However, for those who want the next step up, see below.

The Rev9 Hyper Street II Coilovers feature top hats, some with camber plates, 32 way adjustable shocks, spanner wrenches and spring rates that allow for a comfortable ride yet more focused on the weekend warrior.

These Rev9 Coilovers above come with camber plates, allowing easy adjustment of camber correction or dialing in more negative camber.

Just like the Rev9 Hyper Basic Coilovers, these Hyper Street II are 32 way dampening adjustable.

So after a review of the specs and features here’s how we recommend customers look at these two sets of coilovers.

Rev9 Coilvers – Hyper Basic: Good for those who need to replace their shocks and also want to add adjustable springs. These are a great budget upgrade.

Rev9 Coilovers – Hyper Street II: Good for those looking for even more out of their budget coilovers, including top hats and possibly camber plates (depends on application).

Toyota Tundra Headlights – Sequential Turn Signal Upgrade

The 2014 to 2019 Toyota Tundra is an awesome truck. Legendary Toyota reliability, enough power to tow 10,000+ lbs, and arguably one of the best looking full size trucks on the market. The downside to this generation Tundra is that the truck is pretty outdated and doesn’t have a lot of the bells and whistles of the newer generation trucks. Luckily, the aftermarket provides a lot of those upgrades, and an upgrade that’s one of my favorites is the Spec-D Toyota Tundra Sequential Headlights upgrade.

Above, you can see how these headlights give the Tundra a fresh and updated look. They include daytime running lights, sequential turn signals (see photo below), and come in 4 different colors to match your Truck.


The sequential turn signal is just so cool. It really is a head turner and helps you get noticed. Not only is it good looking, it makes sure that people ahead of you have a better chance of seeing your turn signal and your intent to turn.

The lights, as you can see above, are also bright. Here you can see what they look like turned on and how bright the DRL (daytime running light) C-bar is.


The LED DRL and LED Signal lights are both Neon Tubes so they are really bright and long lasting. The high beam and low beam bulbs are standard H7 bulbs and can be upgraded to ultra bright H7 LED bulbs.

These Spec-D lights fit all 2014 to 2019 Toyota Tundra trucks without the OEM LED strip and without factory headlight level adjusters. If you do have the OEM LED strip and factory headlight level adjusters, the lights will still physically fit, but you would need to do some wiring to connect them as the harness won’t be plug and play.

Tesla Model 3 Performance Gets Lowered with Eibach Pro Kit Springs


Our customer wanted to share some pics of his Tesla Model 3 Performance before and after installing Eibach Pro Kit Lowering Springs. Above, you can see the Tesla Model 3 Performance has a lot of wheel gap from the factory and could definitely use a set of lowering springs. The Eibach Pro Kit works with the factory Model 3 shocks and lowers the car 1 inch in the front and 1.4″ in the rear to give the car a perfect stance.

Below you can see what the car looks like after the Eibach springs have been installed. Wheel gap has been dramatically reduced and the car has a much better stance. We think this is a great upgrade for anyone with a Model 3 Performance who wants to maintain good ride quality, use the factory shocks, and have an inexpensive way to give the car a modified look.

DIY: Ford Escape Rear Camber Arms Install

Our customer, Dean, created a write up on his install of the Godspeed AK-127 Rear Camber Arms on his 2017 Ford Escape SE. We hope this helps anyone who is interested in how the install goes.

Installed the Godspeed AK-127  upper camber arms on my 2017 Ford Escape SE

First off, You must buy a high quality T60 Torx bit on a 1/2” drive socket and get creative on using it to remove the inner bolts, The access to those bolts are very limited in tight quarters but doable. The nut is welded onto the frame so no need to hang onto it. I ended up using a 1/2” swivel and a 3” extension on the drivers side just to loosen it up, then used a pair of Visegrips on the T60 bit to finish removal because the fuel tank would interfere with using the extension. On the passenger side I was limited to only using the Visegrips, I’m sure there’s a factory tool but I used what I had. The fuel tank is close so be careful as to not use it for leverage. The bolt at the knuckle is a 15mm, piece of cake there.

Once the stock camber arm is out, measure the distance between the bushings any way you like and statically set the same distance on the Godspeed arms, both of them. Bury both the  boss into the arm and the rod end into the boss and turn the boss outward to desired length while holding the rod end static, refer to the pics, you will see that equal amounts of the male thread are exposed, this ensures there is still enough thread buried in the boss and the arm and does not compromise the overall strength.
Hand tighten the nuts, RH threads on the boss, LH threads on the rod end and double check your distance.Install was simple, I found it easier to bolt the inside section first (T60 bolt) then the knuckle end, I used the jack under the knuckle to raise/lower to align the holes for the 15mm bolt.

Access to the 1-1/8” adjustment nut and the 1-1/8” lock nuts are limited too, use a short or cut open end wrench for those.

I personally kept the stock length between the bushings in the Godspeed arms because I previously lowered the rear about 3” and that automatically gave me 3 degrees of negative camber which is ideal for my setup.

You can very easily adjust the camber via the center nut, which is the boss of the unit.

BTW I always put generous amounts of Antiseize or Neverseize (same thing) on the male threads of the arm parts and the OEM bolts.


On the difficulty scale I give the removal of the T60 an 8 out of 10 and the rest of the setup install a 4.

Hope this helps someone out, please seek professional assistance if you don’t completely understand this write up and don’t forget Safety First.

Thanks for the writeup Dean!

Godspeed Coilovers – MonoSS vs. MonoRS vs. MonoMAXX

One of the most common questions we get for our Godspeed Project coilovers is, “What’s the difference?”  Redline360 carries Godspeed’s three main coilover lines.  They are the MonoSS, the MonoRS and the MonoMAXX.  This article will break down the main differences between the three to help you determine what suits your needs best.

First, the similarities.  The biggest one is that they are all monotube design dampers.  Even the entry level MonoSS comes with monotube dampers.  A lot of offerings from other companies start with twin-tube design as their entry level.  They are cost effective and provide decent handling and control for most situations.  However, monotube dampers offer a much higher level of performance and consistency than twin-tube designs.  Most, if not all high-end shocks are monotube. 

The second thing that all Godspeed coilovers share is that they all have independent pre-load and ride height adjustability.  What this means is that you’re actually adjusting ride height of the car by shortening or lengthening the entire shock body instead of just moving the spring lower down the shock.  The biggest advantage of this is that you can lower your car without sacrificing the travel of the shock.  Secondly, the spring will always stay pre-loaded, so you don’t have a spring that is flopping around when the shock is fully uncompressed.

MonoSS – These are Godspeed’s entry level coilover model but have features that aren’t typically found in other brand’s entry level offering.  The two aforementioned features common to all Godspeed models are the most significant.  All MonoSS dampers are made from carbon seamless steel and feature 16 levels of adjustment.  The oil used in the damper is a high-quality race shock oil which stays consistent in tough conditions.  The aluminum top hats include a Japanese KOYO bearing pillow ball mount.  If applicable, adjustable camber plates are included.  These are perfect for the street but can handle a track day with no problems.

MonoRS – The MonoRS are the middle child in Godspeed’s street coilover line.  These step it up a notch by offering a damper that can be even more finely tuned with 32 levels of rebound adjustment.  The dampers all have an anti-corrosion and anodized finish.  Most of the components in the MonoRS line are CNC machined billet aluminum which provide additional weight savings.  MonoRS kits include also adjustable camber plates in applicable cars.  This allows you to dial in more aggressive camber settings for additional grip when cornering.  These are great step in between the MonoSS and the MonoMAXX.

MonoMAXX – This is Godspeed’s top shelf street coilover before getting into more race oriented products.  The dampers in this line have an amazing 40 levels of adjustment and a larger 44mm internal piston.  MonoMAXX uses a high quality Italian shock oil that can withstand the extreme temperatures of the track.  These dampers use T7075 forged aluminum or carbon steel bits to keep weight down while still maintaining strength.  The MonoMAXX is a great choice for a street car that sees a lot of aggressive driving and track days.

Whatever series of Godspeed coilovers suits your needs, be assured that you are getting a high quality product at an excellent value.  Godspeed Project suspensions hold numerous time attack and road racing records.  We have many customers running these coilovers and feedback has been great.  This kind of performance at this price point is hard to believe.  These are all backed by a 1 year limited warranty.

Redline360 carries Godspeed Project’s full line of suspension products.  We are constantly adding new products to our site so if you don’t see what you’re looking for or have any questions, please contact us.

Lexus IS300 Coilovers Guide – (2001 – 2005)

Back in the early 00s, most Japanese sedans were utilitarian, boring and not very sporty.  They were designed to be affordable, safe, reliable people movers for families with children.  Sure, there were some Japanese sporty variants such as the Honda Civic Si and Subaru WRX.  However, none of those could compete with the 3-series BMW and C-class Mercedes Benz.  Enter the Lexus IS300.  This car was introduced to the US market in 2001 to compete against the Germans who had always dominated the entry level luxury sedan segment.  The IS300 had some pretty unique features at the time at an attempt to stand out against its competitors.  Most notably were the now infamous “Altezza” tail lights.  OEMs and aftermarket companies are still producing light housings based on this design almost 20 years later.  A couple of other interesting features were the gauge cluster, modeled after a chronograph watch, and a shift knob that was a solid piece of polished metal.  Powered by the same engine as the non-turbo MKIV Supra and Lexus SC300 and sporting a RWD drivetrain, the IS300 quickly became a popular choice in the import and drift scene.  This has spawned plenty of aftermarket options for the IS300.  Many enthusiasts first turn to updating the suspension.  There are no shortage of IS300 coilover options. Redline360 is an authorized dealer of several brands and can set you up with something that will fit your budget and needs.

In this article, we will review a few of our more popular coilovers for the first-gen IS.  The first group of coilovers we will cover are more street oriented.  These all feature a twin-tube design damper.  These ride just a little bit softer for a comfortable daily ride while still being able to adjust ride height for that perfect stance.

TEIN Street Basis Z – This is TEIN’s entry level coilover.  You get the quality you expect from a well-respected brand like TEIN but for a reasonable price.  While the dampers are non-adjustable, you are still able to adjust ride height to get the stance you want.  These can go as low as -3.5” from stock in the front and -3.7” in the rear.  This kit re-uses your OEM rubber upper mounts for better ride compliance.

TEIN Street Advance Z – This kit is for people that want the same value that the Street Basis Z provides but want an adjustable damper as well.  The rest of the features are identical.  They come with the same spring rates and same range of ride height adjustment.  They also re-use your stock upper mounts. Being able to adjust the firmness of our dampers gives the Street Advance Z an extra dimension of flexibility.

TruHart StreetPlus – This twin tube shock is an amazing value.  TruHart is able to offer all the features at this price point by making the damping non-adjustable.  However, the ride height and pre-load are independently adjustable.  This allows you to go pretty low while still being able to have full shock travel.  These have aluminum pillow ball upper mounts and steel lower mounts for strength.

Function & Form Type 2 – These are a more aggressive twin tube design coilover with a lot of adjustability.  Each damper has 32 levels of adjustment. The ride height and pre-load are adjustable.  You can slam these and get the same amount of shock travel.  Unlike the TEIN offerings above, these come with aluminum uppers with pillow ball mounts.

The following coilover sets all kick it up a notch with monotube design shocks.  The monotube design allows for more consistent shock performance in spirited driving and track situations.  Consistency is key when you are at speed.  You don’t want any surprises when going through a corner at high speeds.

Godspeed Mono SS – Just because this is an entry level monotube coilover does not mean it’s not still packed with features.  These use a rubber bushing in the upper and lower mounts for a more compliant ride.  The powdercoated dampers have 16 levels of adjustment and are filled with race quality shock oil.  Ride height and pre-load adjustments are independent of each other.  These come with a 12kg/mm front and 10kg/mm rear spring.

Megan Racing EZ II – These coilovers are great choice for someone who wants a comfortable daily drive but still wants a high performance monotube damper. They feature 15 levels of adjustment and have aluminum upper mounts with rubber bushings. These also come with a softer spring coming in at 10kg/mm front and 6kg/mm rear for a smooth ride.

Ksport Kontrol Pro – These are a very nice option for a street car that will occasionally see track duty.  This monotube damper has 36 levels of adjustment so you can fine tune the firmness of your ride.  These also have independent ride height and pre-load adjustment, so you get maximum shock travel when lowering.  The coilovers are treated with zinc electroplating to combat corrosion.  These come with 12kg/mm front and 7.2kg/mm rear spring rates.

BC Racing BR Series – BC has gained a large following by producing quality suspension components for years at a very good price.  These monotubes have 30 levels of adjustment which simultaneously adjust rebound and compression.  The ride height and pre-load adjustments allow you to go extremely low while still maintaining full shock travel.  When the shocks reach the end of their life, you have the option of sending them directly to BC Racing for a rebuild. Rebuilding a shock is much cheaper than having to buy a whole new setup.  They come standard with 12kg/mm front and 10kg/mm rear springs.  Custom spring rates and Swift spring upgrades are available.  Please contact us if you need custom spring rates.

Any of the options listed above without a doubt will improve the stance and handling of your Lexus IS300.  Adjustable dampers have a lot of flexibility for different situations, even ones that don’t immediately come to mind.  Imagine if you wanted to add an all-out killer stereo system in your trunk that added 300lbs of weight.  You could offset that by stiffening your rear shocks up a couple notches and maybe raising the ride height a bit.  On the wilder end, what if you decide to swap a V8 or the legendary MKIV Supra TT engine in and need to offset the extra weight over the front of the car?  Adjustable coilovers for your IS300 is the answer.  Redline360 is here for any of your IS300 suspension needs.  If there is a particular brand or model of coilover that you’re interested in but don’t see it listed, leave a comment down below or please contact us and we will be glad to help.

Nissan 350Z Coilovers (2003-2008) Z33 Coilover Guide

Whether it’s track days, drifting or just canyon carving that you’re into, the Z33 chassis Nissan 350Z is a great platform to play with.  Also known as the Nissan Fairlady Z outside of the US, this car is popular for its RWD platform and great balance of power and handling.  The 350Z was a reintroduction of the Z line in 2003, after a 7 year hiatus.  This 5th generation Z car was sold in the US from 2003 until 2008.  They are plentiful and most importantly very affordable these days on the used market.  If you are able to pick up a clean, stock example of a 350Z, chances are that the suspension is probably tired and ready for a replacement.  The single biggest change you can make to improve your 350Z’s handling and stance is a set of new coilovers.

Redline360 offers a broad range of Nissan 350Z coilovers to suit your budget and needs.  We have everything from entry level budget minded setups to track ready setups.  We are constantly adding new products to our catalog so if there is something in particular you’re looking for; don’t hesitate to leave a comment below or contact us by clicking: Contact Us.

That being said, let’s discuss the different types of coilovers, their features and their advantages at different price points.  One thing to decide on for your 350Z is to determine if you want an OEM style setup or “true rear” coilover system.  The front suspension is the same configuration in the front for all kits.  However, with the rear suspension, you have the option of going with an OEM style, also known as a “divorced” set up, meaning that the spring is not sitting over the shock.  The spring sits separate from the shock in a “bucket” along the lower control arm.  The other option is what is known as a “true rear” coilover set up.  This means, the spring will sit over the shock on an adjustable collar, just like the front coilovers.  Here are just a few of the options we offer that have OEM style “divorced” rear configurations.

MSR 24 Way Adjustable – These are a great entry level coilover and provide a lot of value for your dollar.  Aside from adjustable ride height, there are 24 levels of adjustment on the dampers, pillowball upper mounts and 6063-T6 aluminum body construction.

TEIN Street Basis Z – These are a really high quality coilover setup with a name you can trust at a great price.  While the dampers are fixed, these are height adjustable between 0.0” to -3.1” in the front and 0.5” to – 2.1” in the rear.  This setup is great for cars that will primarily only street.

TEIN Flex Z – These are a step up from the Street Basis Z in that they have 16 level adjustable damping and come with reinforced rubber upper mounts.  These feature adjustable height and pre-load so you can lower your car without sacrificing ride quality.  The Flex Z are made and assembled in Japan, yet are still affordable due to newly developed manufacturing techniques.

Function & Form Coilovers – This is an OEM style setup that is ride height and pre-load adjustable. They have 32 levels of damping adjustment for fine tuning of your shocks. The shocks have a twin tube design for a more comfortable daily ride. The flagship coilover for Function & Form, these have excellent build quality.

The arguments for the performance advantages a true rear coilover are often debatable.  Generally, performance-wise, they are the same.  However, there is one notable advantage to using this style of rear coilover.  If you switch to a true rear setup, this allows you to ditch the OEM lower arm that houses the OEM spring and replace it with adjustable toe arms.  For a street car that generally doesn’t need much adjustment, toe arms aren’t necessary but if you think you may need the adjustability in the future, then picking a true rear coilover set up may be the right choice for you.  Adjustable toe arms will also save weight over the large OEM piece.  Another small advantage to true rear setups is that it’s much easier to get to the ride height adjustments.  It’s not too difficult with an OEM style setup, but it’s further inboard and requires just a bit more effort.  Here are some of the options we offer that use a true rear setup:

TruHart StreetPlus – This is an ideal choice for a budget setup using a true rear setup.  These have adjustable ride height and pre-load.  The non-adjustable twin tube dampers are pre-set specifically for these spring rates.  The zinc coated shock bodies ensure that they’ll stay protected from the elements and fight off rust.

Godspeed Mono SS – These coilovers pack so many features for its price point.  It’s a true rear design using an aluminum shock body with forged aluminum brackets.  The shocks are a monotube design using race quality shock oil that has 16 levels of adjustment.

Another factor to consider is the shock design.  The two major types are twin tube and monotube.  From the outside, they look similar.  Internally there are major differences that factor into the performance of the shock.  In a twin tube design, you basically have a tube within a tube.  The inner tube houses the shock fluid where the shock piston is, while the outer tube is where the gas is housed.   When the piston is compressed, it forces the fluid into the outer tube.  The oil and gas work together to control the shock.  In a monotube design, it’s just a single tube and the top portion of the shock houses fluid and the bottom part of the shock, which is separated by the piston, is gas charged.  Together these work to control the motion of the shock piston.  While today’s twin tube designs are very good and are suitable for street and occasional track use, monotube shocks offer a larger shock piston, more capacity for shock oil and a much lower chance of cavitation.  The monotube design is superior but comes at a higher price point. 

Redline360 has got you covered if you’re looking to step up to a monotube coilover setup.   Here are a few examples:

Megan Racing EZ II – The Megan Racing EZ II coilovers are a monotube design damper with 15 levels of adjustability.  These have 10k front and 8k rear spring rates and are perfect for canyon carving and the occasional track day while still being comfortable enough to daily drive.

BC Racing BR Series – BC Racing’s BR Series is one of the best street/track coilovers available.  These are wildly popular among enthusiasts of many different car models, and for good reason.  They feature a monotube design with 30 levels of damping, adjustable height and pre-load and are fully rebuildable.  They also offer an extreme drop version which allows you to lower your car up to 4” if you so desire. Also available as a true rear coilover setup.

KSport Kontrol Pro – The Kontrol Pro from KSport is another quality coilover system using a monotube design. These have 36 levels of adjustment for compression and rebound (together). The ride height and pre-load are both adjustable so you don’t have to sacrifice ride quality even if you lower your car an aggressive amount.

There are so many advantages to switching to a coilover setup.  You can adjust the ride height and you can adjust how soft or firm you want your ride to be.  You can spend a little bit of time before a track day to dial in a lower stance and stiffen up your shocks.  At the end of the day before leaving the track, crank everything back down for a plush ride home and to work the next day.  One other major advantage to having fully adjustable ride height is that you will have the ability to corner balance your car for optimum handling.  Corner balancing is a must for cars that see regular track days.

The best thing about all the choices of coilovers for your 350Z is that there is most likely going to be something to fit your needs and budget.  The Nissan 350Z has always had great aftermarket support, and products for this platform will continue to develop.  A good quality suspension set up doesn’t have to be expensive.  Even the lowest price coilover Redline360 offers will do great with proper install and alignment.  To see our listing of coilovers, please click here: Nissan 350Z Coilovers.
