Shifter Stop for 2015 WRX

If you read the entire post from 2015 WRX and STI Exposed article, you would know that the 2015 WRX shifter is one of the things that I feel is terrible about the car. Normally cars that use cable shifters have a very positive feel and provide excellent feedback, but that is not the case for the 2015 WRX. This all started the first day I drove the car for an extended period of time. I first hated how the shifter [...Continue Reading...]

Why You Want A PSRS For Your Car

We can make this really simple. If you live on the east coast and/or  own a 2008+Impreza/WRX/STI/Legacy and have more than 40,000 miles on your car, you need this part. Click HERE! OEM Bushings Will Fail… Ok being serious now, there are many reasons to want this part. They fail, they are super soft, negatively effect handling under braking and acceleration, and can add to wondering of your car from ruts in the road. Secondary reason to want this part is the [...Continue Reading...]

LED Bulb Kit from PIAA

One of the features I really like about the the 2015 WRX and STI is the LED Headlights standard on the STI,  WRX premium and limited models. The headlights are absolutely amazing at night and are far superior to the older HIDs that came on the STI’s. Subaru did such a good job on this car and its hard to find things that are flawed and or need improving. With that said, there is one thing I found. The fog [...Continue Reading...]

2015 WRX Shifter Bushing, 20 Days From Idea To Customers Hands!

4/3/14, We found a part we could vastly improve upon. 4/20/14, We had it ready to ship to customers.  During exploration of the 2015 WRX, we found a part we could make much better than the OEM part and at the same time improve how the car feels. The shifter bushing that controls the front to back action on the transmission, uses a really soft rubber bushing to connect the cable to the shifting mechanism. This soft bushing deflects under [...Continue Reading...]

PERRIN STI Equal Length Header

Updated from July 2010 post with new pics and new data! When Subaru released the Version 8 STI in Japan we noticed how they moved to a twin scroll turbo and equal length exhaust manifold. This is what inspired us to make our first header for the WRX/STI! Would taking the equal length design of this JDM header and adapting it to fit our US cars actually make a difference in power? Would it spool worse?  How would the sound [...Continue Reading...]

3.0" BRZ/FR-S Exhaust Dyno Results and Stage 3 Tune!

We are always looking to push the limits of the cars we build parts for. We have made huge power with the STI’s, WRX’s, EVO’s and then with the BRZ using a Vortech SC kit. In all these situations the cars are boosted in one form or another, which makes it really easy to make more power. Now we want to push the limits of the stock BRZ engine in its naturally aspirated form. In this first post we will [...Continue Reading...]

3.0" BRZ/FR-S Intake Dyno Results

From the very beginning, we were big on making sure people knew that our BRZ/FR-S cold air intakes were safe, wouldn’t throw check engine lights, and/or need a tune. These were very important items to hit on as there are many myths surrounding Cold Air Intakes. Some of these myths are, intakes cause CEL’s (Check engine lights), lose power, only make cool sounds, and require ECU tuning or require ECU re-learning to get the benefits from it. We spent a ton [...Continue Reading...]

BRZ / FR-S Cold Air Intake Design.... Part 2

We spent a long time designing and testing our BRZ intake system to ensure that when our customers recieve the part, it will make the HP we claim, not cause any drivability issues, and be easy to install. After seeing many intakes with bogging issues, drivability issues, and poor MAF sensor placement, I knew that our intake would be a hit. If you missed the first blog post about our intake and design process, you can read up about the initial design in PART [...Continue Reading...]

PERRIN BRZ/FR-S Oil Cooler

It may be obvious to some that you want to keep your oil cool under heavy load and extreme conditions. This keeps your oil from becoming too thin, or breaking down,which makes it less effective and could lead to premature engine wear or even engine failures! Another reason to keep your oil temps down is it keeps other engine components cooler which is good for HP. Until the BRZ/FR-S platform, we never really noticed oil temps playing a role as [...Continue Reading...]

Inlet Hose for BRZ / FR-S

One of the first things we noticed on the BRZ/FR-S engine is that the OEM inlet hose could use some major improvements. From the resonator chamber, and the noise generator tube, to the fact its not very smooth on the inside, this for sure was a part that we could make better and make some HP with. Lets look at the stock part first. You can see below that there are a bunch of extra pieces to the OEM part. You [...Continue Reading...]
