Paragon 6-Piston Front Big Brake Kit – BMW 3 Series, 4 Series, 5 Series, 6 Series (GXX)

This complete, track-ready big brake kit is engineered for BMW 3, 4, 5, and 6 Series models on the GXX chassis platform. Designed to deliver race-level stopping power with consistent performance, it features Paragon’s PA015 or PA035 6-piston calipers and high-efficiency 2-piece rotors. The only difference between the two calipers is the maximum rotor size they can accommodate—giving you flexibility based on wheel fitment and intended use.
