Our Philosophy: Balanced, Engineered Performance
Power, braking, suspension and appearance—these are the variables you take into consideration when seeking more performance from your WRX. ASR Performance addresses each of these pieces of the performance puzzle, and offers truly balanced performance solutions.

The new-age Subaru WRX is an adequate performance vehicle right off the showroom floor. Sporting 227 horsepower, all-wheel-drive and a sport-tuned suspension, the WRX set the automotive world ablaze when it first reached these shores in 2001. However, like all production cars, the WRX's overall performance can be improved.

The aftermarket exploded even before the WRX was being sold in the U.S. With that aftermarket support came a lot of great performance upgrades. Unfortunately, it also created a lot of confusion.

ASR’s genesis was based in large part on finding the best quality parts and then grouping them into well-thought-out and engineered stages, and in the process, demystifying the performance upgrade process. Our stages use the best parts and processes available. You can rest assured if you’re driving an ASR-prepared WRX, you are in fact driving the very best.

The WRX is not a one-dimensional car, so ASR doesn't offer one-dimensional solutions. Instead, we took a broad approach to WRX performance. We designed each stage as building upon the one previous. Many parts were developed in-house, using the best materials and workmanship.
