We have long loved the ease of upgrading to larger Competition Package front rotors on the E46 M3, but have not loved the price! Designed in-house at our Wadsworth, Ohio facility, these brackets allow for an economical upgrade to 345x28mm CSL/ZCP Competition package front brake rotors. Utilizes your stock brake lines, calipers, and brake pads, while allowing for extra brake torque and heat capacity.
Use with our ECS 2-piece brake rotors, Genuine BMW rotors, or any 345x28mm E46 M3 rotor. Functionally identical to Genuine BMW part number 34112282619.
