2006 Lexus IS350 with Perfect Stance on Megan Racing EZ Street Coilovers

Our customer Mike came to us looking to add coilovers to this 2006 Lexus IS350 to give him the stance he wanted. Mike and his father painted the car Porsche Mint Green at their shop in Louisiana called Auto Perfection Inc and wanted to give it the right look. Mike went with Megan Racing EZ Street Coilovers , one of the most popular choices for the IS350, to lower his car and maintain good ride quality. We think the car turned out great, and the stance looks awesome.

C7 Corvette Z06 Heat Soak or ECU Timing Being Pulled?

There have been a lot of people complaining lately that after a few track laps their 2015 C7 Corvette Z06 feels slower. Initially people though that the supercharger was getting too hot, and so it was heatsoaking, effectively making the air going through the supercharger to the engine too hot and not making as much power.

GM has made a statement on this topic and has said that the problem is that the car is designed to pull back timing after some use, which helps to prevent any powertrain damage. They believe that the majority of owners will never race their C7 Z06, so they will never have this problem, or they simply won't notice. GM has said that there are aftermarket products you can purchase that will allow for you to override this feature in the ECU.

Some have said that the reason the ECU pulls back timing is because of the heat soak. The ECU sees the supercharger getting too hot, so it pulls back timing to prevent any engine damage. The real reason is still unknown, but those who are getting their C7 Z06 Corvettes dyno'd will soon test to see if the ECU pulls back timing when the supercharger air temps reach a certain temperature to cause heat soak.

If anyone has any data to prove either of the above, please contact us and we can share it here, so we can get down to the bottom of the power loss in the new Z06.

2013 Subaru Forester XT Sleeper with COBB AccessPort


When our customer, Will, told us he was building a sleeper 2013 Subaru Forester XT Turbo, we were intrigued! Check out the modifications below that allowed for him to create 228 horsepower at all 4 wheels, and a very impressive 351 ft/lbs of torque! All of this through a stock exhaust, with minimal mods. The COBB AccessPort is a great tuning device, and we covered it in this other post previously.

Cobb Accesport
Cobb Downpipe
Cobb Intake with box
(Stock exhaust) - Sleeper!
Whiteline 22mm swaybars and endlinks
Dyno tune by PIA in Tacoma, WA

I looked long and hard for a 2013 Forester XT Touring with low miles, finally I tracked one down 175 miles away. It was well worth the search amd the wait. Before I even had license plates I had to fix the body roll and release the power held back by restrictive parts and tuning. It's now making a peak of 351awtq and 228awhp running 16lbs of boost on a custom map from PIA in Tacoma, WA. I kept the exhaust stock for road trips, and so my wife wouldn't kill me. My 16 month old daughter loves the car and makes growling noises every time I start it up. Thanks to Redline360 and PIA for the amazing customer service and mods. It's truly an amazing sleeper, and handles perfectly for daily driving and the ocassional (okay, more than ocassional) hard corner. I would highly recommend both Redline 360 and PIA to anyone looking for their car to perform at its best!

What an awesome daily driver! What do you think? Let us and Will know in the comments below!

Ultimate Guide: Subaru BRZ Lowering Springs and Scion FR-S Lowering Springs Reviews


We have a lot of customers with the Subaru BRZ and Scion FR-S asking us what lowering springs we recommend. It's really difficult to say as the brands we carry are all high quality, so the decision really lies in the drop you want, and the spring stiffness. It also depends on what type of driving you will be doing. So what we did was put together a list of the Scion FR-S Lowering Springs and Subaru BRZ Lowering Springs that we carry to help you decide on what is best for you.

We'd love to hear your reviews and feedback in the comments. Let us know what your favorite springs are for your FR-S or BRZ.

B&G S2 Sport Lowering Springs
B&G S2 Lowering Springs Scion FR-S (2013-2014) 92.1.101
B&G S2 Lowering Springs Subaru BRZ (2013-2014) 86.1.030

Lowers in the front: 1.4"
Lowers in the rear: 1.4"
Spring Rate: Progressive
Warranty: Lifetime

Review: B&G Lowering Springs are nice for those who want to lower their BRZ or FR-S but maintain a good ride. B&G offers almost a 1 and a half inch drop front and rear which is more geared toward the aggressive drop.

Eibach Pro Kit Lowering Springs
Eibach Pro Kit Springs Scion FR-S (2013-2014) 82105.140
Eibach Pro Kit Springs Subaru BRZ (2013-2014) 82105.140

Lowers in the front: 1.0"
Lowers in the rear: 1.0"
Spring Rate: Progressive
Warranty: Million Mile

Review: Eibach Pro Kits are great for those who want to reduce some of the fender gap, but don't want to be too low. One inch drop front and rear is considered minor, but it's good for those who don't want to worry about rubbing aftermarket wheels and tires on their fenders. Of course it depends on what size aftermarket wheels and tires you run, but this is a generally a safe bet. Great ride.

Eibach Sportline Lowering Springs
Eibach Sportline Springs Scion FR-S (2013-2014) 4.10582
Eibach Sportline Springs Subaru BRZ (2013-2014) 4.10582

Lowers in the front: 1.4"
Lowers in the rear: 1.4"
Spring Rate: Progressive
Warranty: Million Mile

Review: If the Eibach Pro Kits didn't lower your car enough, the Sportlines might be for you. Eibach Sportline is made to lower about half an inch more than the Pro Kit, so you get a more aggressive stance and clear up even more of that wheel gap.

H&R Sport Lowering Springs
H&R Sport Lowering Springs Scion FRS (2013-2014) 54408
H&R Sport Lowering Springs Subaru BRZ (2013-2014) 54408

Lowers in the front: 1.0"
Lowers in the rear: 1.2"
Spring Rate: N/A
Warranty: N/A

Review: H&R Sport Springs give you about the same drop as the Eibach Pro Kit, but lower a bit more in the rear. H&R prides itself on offering a good ride, and many of our customers give their Sport springs great reviews.

H&R Sport Lowering Springs
H&R Super Sport Lowering Springs Scion FRS (2013-2014) 54408-77
H&R Super Sport Lowering Springs Subaru BRZ (2013-2014) 54408-77

Lowers in the front: 1.2"
Lowers in the rear: 1.4"
Spring Rate: N/A
Warranty: N/A

Review: H&R Super Sport Springs are for those who want to be a bit lower than what the sport provides, so these lower the car an extra .2" front and rear.

Hotchkis Lowering Springs
Hotchkis Lowering Springs Scion FR-S (2013-2014) 19445
Hotchkis Lowering Springs Subaru BRZ (2013-2014) 19445

Lowers in the front: 1.0"
Lowers in the rear: 1.0"
Spring Rate: N/A
Warranty: 3 Years / 36,000 Miles
Made in the USA.

Review: Hotchkis springs, made in the USA, are designed for comfort in the mind. Minimal lowering, but enough to close the gap.

Megan Racing Lowering Springs
Megan Racing Lowering Springs Scion FRS/Subaru BRZ (2013-2014) MR-LS-SFR12

Lowers in the front: 1.75"
Lowers in the rear: 1.25"
Spring Rate: Progressive
Warranty: 3 Years

Review: The Megan Racing springs are for those who want a serious drop. These are designed to go low, but still offer a good ride. One thing common with springs that have big drops is they tend to sag even more over time. Megan Racing springs are unique in that they have a very high tensile strength steel that resists this premature sagging pretty well.

RS-R Super Down Lowering Springs
RS-R Lowering Springs Scion FR-S [Super Down] (2013-2014) T065S

Lowers in the front: 1.1"
Lowers in the rear: 1.3"
Spring Rate: N/A
Warranty: 1 Year / 12,000 miles.
Made in Japan.

Review: RS-R Springs, made in Japan, are arguably the best riding springs we sell. RS-R really takes the daily driver into consideration to create a lowering springs that works with the OEM geometry, lowers just the right amount, and maintains a comfortable ride. These springs are actually designed to be used with the factory shocks.

Tanabe GF210 Lowering Springs
Tanabe GF210 Lowering Springs Scion FRS/Subaru BRZ (2013-2014) TGF166

Lowers in the front: 0.6"
Lowers in the rear: 0.9"
Spring Rate: N/A
Warranty: N/A

Review: Tanabe GF210 lowering springs give you the least amount of drop that we sell. This is good for those that want to lower their car a little, and want to keep as much of the factory ride as possible.

TEIN HTech Lowering Springs
TEIN HTech Springs Scion FR-S (2013-2014) SKSA0-G1B00
TEIN HTech Springs Subaru BRZ (2013-2014) SKSA0-G1B00

Lowers in the front: 1.0"
Lowers in the rear: 0.8"
Spring Rate: Progressive
Warranty: 1 Year

Review: TEIN HTech lowering springs, also known as High Tech, are TEIN's luxury springs, which are designed to give you a modest drop with maximum ride comfort. Good for those who are all about the ride, and just want to close some of the wheel gap.

TEIN STech Lowering Springs
TEIN STech Springs Scion FR-S/Subaru BRZ (2013-2014) SKQ54-AUB00

Lowers in the front: 1.4"
Lowers in the rear: 1.2"
Spring Rate: Progressive
Warranty: 1 Year

Review: TEIN STech Lowering Springs are a relatively aggressive drop, but still offer much of the benefits of a more luxury spring as ride comfort is key. TEIN STech's are a popular choice as they have a drop that most customers are looking for without being too aggressive.


Review: TEIN STech Lowering Springs Scion tC – TEIN SKL52-AUB00

For more info or to order: Click here

Here we have the TEIN S-TECH Lowering Springs, part number SKL52-AUB00 for the 2005 to 2010 Scion tC.

These springs lower your tC, 2.4 inches in the front and 2 inches in the rear.

What’s nice about the S-TECH lowering springs is they are progressive design. This means as the springs compress, their spring rate goes up. So under normal daily driving, the springs will feel softer and have a better ride. Under compression, they will stiffen and give you better handling. This is a great spring for those who want to lower their car, but maintain a good ride.

These springs come with this silencer rubber to prevent any unwanted noise and have a 1 year warranty against defects and sag. TEIN guarantees they won’t sag more than 5mm

These springs work well with the factory shocks, or with performance aftermarket shocks.

We have these on our site and they include all 4 springs for a complete setup, plus warranty information and TEIN stickers.

Review: RS-R Lowering Springs Lexus IS250/IS350 Part # T195D

For more info or to order: Click here

Here we have the RS-R Lowering Springs, part number T195D for the Lexus IS250 and IS350 rear wheel drive.

These lowering springs lower your Lexus 1.2 inches to 1.4 inches in the front and 1 inch to 1.2 inches in the rear. They generally settle at about 1.3 inches front and 1.1 inch rear.

RS-R designs these springs to give you exceptional ride quality and comfort, while lowering your center of gravity and improving handling, braking and overall performance.

Unlike other lowering springs, RS-R designs these around the OEM suspension geometry, so these springs take full advantage of your suspension to make it handle even better. You’d be surprised how some other lowering springs feel like they improve handling, but actually show worse track times because balance is thrown off.

These springs work great with your factory shocks and are designed and built in Japan.

These are some of the best quality springs we sell, and we highly recommend them for your IS250 and IS350.

We’re an authorized RS-R dealer, and offer these new with manufacturer’s warranty. Check them out by clicking here.

What are Coilovers and Coilovers vs Springs Explained


What are coilovers?
By definition, a "coilover" is short for "coil spring over shock". All this means is you have a coil spring literally sitting over your shock or strut. Other suspension systems such as leaf springs, keep the shock and spring separate. When discussing performance suspensions, people refer to coilovers as suspension systems that are height adjustable and include both the shocks and the springs, usually pre-assembled, paired perfectly for each other and ready to be bolted on.

See the various brands of coilovers.

Coilovers vs Springs
Before we get into more detail on coilovers, we wanted to explain the difference between coilovers and lowering springs. Many of our customers are undecided on which route they want to go with their suspension. Some just want to lower their car, while others want the ability to adjust the height, while others want even more flexibility with rebound and compression adjustments on their shocks. Lowering springs simply let you lower the car, but do not offer you any adjustments. Lowering springs have a pre-set amount of drop, and you buy the springs based on the amount of drop that you are looking for. You can use them with factory shocks, if your factory shocks are still in good shape or your car is new, or with a performance shock. The problem many people run into is that they buy one brand of springs and one brand of shocks, and they are not always a good match for one another. The springs might be too stiff for the shocks, or the shocks too stiff for the springs and you run into a condition that your car is low and "feels" like it handles better, but in fact actually handles worse than stock. Happens all the time. This is why when it comes to coilovers vs lowering springs, if budget allows, we always recommend to go with the coilovers.

So then there's the question of - well, which coilovers do I buy? Which coilovers are the best for my car? Are cheap coilovers as good as expensive coilovers? What's the difference between cheap coilovers and expensive coilovers? Am I just paying for the name? All very good questions, and we hear it often enough here at Redline360, that we decided to write a blog post about it.

Coilovers come in all shapes and sizes. Everything from sleeve type coilovers, to full bodied race coilovers with separate oil canisters for the ultimate adjust-ability and performance.

Here are some of the most popular types of coilovers:

Coilover Sleeves
Coilover Sleeves are essentially one step above lowering springs. These are height adjustable, and come at an entry level price. Some customers really like that they can pick their springs rates and length of the springs.

  • Price: Lowest
  • Includes Shocks: No
  • Height Adjustable: Yes
  • Works with Stock Shocks: Yes, but not recommended
  • Camber Kit: Not Included
  • Top Mounts: Usually Included
  • Example: Ground Control, Megan Racing Slip Over

Non Shock Adjustable Coilovers
Non shock adjustable coilovers are considered entry level. These coilovers come with shocks and are height adjustable, but you are not able to adjust the stiffness, compression or rebound of the shocks. Depending on application, most are pre-assembled and include top mounts, and are ready to be installed. Excellent choice for those who want to lower their car, have ability to adjust the amount of lowering, and want something reliable.

Shock Adjustable Coilovers
Shock adjustable coilovers are like the non shock above, except they have better shocks that you can set to really dial in your suspension. Many of these are our most popular selling coilover, and allow people to soften the ride for daily driving, or stiffen it up for track use.

Shock Adjustable Coilovers with Camber Kit
These coilovers are the best balanced suspension upgrade, and include height adjustable coilovers with adjustable shocks, and front camber kit (sometimes also rear camber kits are included). So this way, not only are you getting a full suspension setup, but you don't need to buy a separate camber kit.

Are all coilovers made the same?
We get many customers asking us why some coilovers are so much more expensive than others. Some coilovers on the market are dirt cheap, and while this is good for the consumer to have a variety of options, you need to be careful when it comes to coilovers. Keep in mind that coilovers are one of the most important suspension components, and safety and performance need to always be a concern. Cheap coilovers are typically built with the worst materials, and while they do provide you the same functionality, they do not offer you the same longevity, performance or safety of a quality coilover. If you are not sure what's right for you, ask below, or send us an email and we can help guide you to the right setup for you, depending on your needs and budget. Sometimes if the budget doesn't allow for a quality coilover, it might be best to wait until you can save, or you might just have to go with a completely different setup.

World’s First Nissan GT-R Sedan? Check out this GT-R 4 door!


A 4 door Nissan GT-R?

A customer asked this this today. When we told him there's no such thing as a 4 Door GT-R, he showed us this picture he found online. Of course, if it's on the internet, it must be true, right?

Looks to be a sedan of some sort that was converted to a GT-R by way of a body kit. The kit looks to be pretty well done, and the body lines even line up. Could be photoshop, but I think this one might actually be a real body kit. Looks like someone really went out of their way to do this.

Can't tell what kind of car this started off as, but if anyone knows, tell us in the comments below.
