Steering Dampener Lock-Down

Problem…                                                 One day I was doing some R&D work on our WRX and noticed how sloppy the steering felt when the car was in the air. For whatever reason I was turning the steering wheel back and forth quickly and I could feel a strange rubbery feeling to it. This rubbery feeling drove me to look at […Continue Reading…]

Hella Horn Brack.... I Mean Fog Light Bracket

The Idea A while ago, a customer said something to me that made me think about a better purpose for the PERRIN Horn Bracket. I mean everyone loves a good horn and loves that look of the Hella horns behind their bumper. But really, who uses their horn enough to warrant that. For a matter of fact, why not just install some red circles behind your grill Ok, kidding aside, while horns are good to have and I loved my […Continue Reading…]

Gurney Flap for 2015 WRX

See our Poll on NASIOC to help us figure out which style you like!    NASIOC Poll for PERRIN Gurney Flap How This Came To Life Like a lot of parts I come up, it starts with something I make just for my car that I think no one else will want, and then it turns into a real part. This is exactly how the Wing Riser Kit for the 08-14 STI Hatchback happened as well. One day I made a […Continue Reading…]

Firewall Grommet for 2015 WRX/STI

Upon the release of our PERRIN Electronic Servo Driven Gauges, we stumbled onto a perfect part to make, that would compliment them being installed on a 2015 WRX or STI. Something everyone would need and could afford! In the past, we would have to slit a large rubber boot behind the turbo to fish wires and things through to get from the inside of the car to the engine bay. This was a simple location, but the issue is water […Continue Reading…]

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 wandering 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…]
