4th Gear Set for Spec Boxster

Fits the original 1999 Porsche Boxster (DVY transmission), per PCA/POC spec racing.

Stock gears break often in racing, and they are no longer available from Porsche. These gears replicate stock functionality with more reliability.

We stayed true to the stock ratio. They are cut helically, but with less angle. Using modern proprietary race-proven profiles, alloys, and hardening, these gears are the ultimate upgrade for your race car.

(CWA variant gears are in the works.)
