Subaru spent a great deal of timing engineering the WRXs braking system, and its often easy to upset this balance when upgrading to aftermarket components. The key is to fully understand how the brake system was originally designed, and engineering within that criteria. Born from that philosophy, we offer our Stage 3 Brake Package. A key benefit of upgraded brakes during racing or street driving is not simply shortening the braking distance during only one stop, but instead the ability to brake on the edge consistently and reliably. Maintaining the balance is critical, otherwise the car will get upset during threshold braking into corners – reducing lap times and making the car hard to drive in a fast, repeatable manner. The results from our Stage 3 Brake Package are not only shorter braking distances but better control before engaging ABS, more consistency, and a much better overall balance of the braking system when compared to the other performance brake systems we have tested. Engineered for the demands of everyday use – proven through extensive motorsports activities. Our front brake kit represents the best balance between race-bred performance and daily driven reliability. Due to the care and focus of our design, this kit is completely civilized for daily driven cars. Spared from the many squeaks, rattles, and frequent rebuilds found in other kits utilizing off-the-shelf, race-only parts. The system is manufactured to our specifications by Stoptech and features lightweight aluminum 4-piston calipers, huge 328mm 2-piece front brake rotors, COBB specification front brake pads and our stainless steel front brake lines. The specifications are a direct result of our Subaru-only focus and expertise of the Subaru vehicle combined with Stoptechs expert ability to manufacture the highest quality braking components available At COBB Tuning, we are involved with many race programs as well as extensive street testing. You can be confident that the system has been designed and thoroughly tested in real-world environments, not just on paper or through marketing exercises.
