YL CALIPERS/DRILLED ROTOR

Rear, 2-piston, balance-optimized, big brake kit for E46 M3. This kit drastically improves braking performance on and off the race track. It features drilled or slotted 2pc Aerorotors (345mm), 2-piston ST22 forged calipers, forged caliper brackets, Sport pads, and DOT-compliant stainless brake lines. StopTech's patented Balanced Brake Upgrade® matches brake components with vehicle weight, master cylinder size, and weight transfer under braking for ideal brake bias and tire contact. Aerorotors have a patented directional vaning pattern that expels hot air to keep the rotor cool and your braking performance on point. ST22 calipers are forged aluminum, center bridge reinforced, and feature vehicle-specific piston sizes with high-temp silicone brake boots. StopTech Sport pads offer strong initial bite and consistent performance through a wide temperature range for street and occasional track use. 18" wheels required. Special Application Notes: not for cars with ZCP Competition Package. These kits have been discontinued by Stoptech/Centric.
