YL CALIPERS/DRILLED ROTOR

This is a front, 6-piston, weight-optimized, balanced big brake kit for the BMW E82 135i. It features 20% lighter ST60R forged calipers, 50% better cooling airflow in Aerorotors, hard-anodized coating on calipers and rotor hats, forged caliper brackets with mounting studs, and includes brake pads and stainless steel brake lines. These kits are optimized for exclusive track use, offering uncompromised braking performance, reduced fade, and model-specific piston sizing. 18" wheels are required for clearance. There are two versions: Trophy Sport (with dust boots for street use) and Trophy Race (without dust boots, for racing/track only). Periodic rebuilds and regular fluid changes are recommended. Calipers are available in a dark-grey military-spec hardcoat.
