BMW E46 M3 CSL 2-Piece Rotors

The E46 M3 is a favorite to many enthusiast with its smaller lightweight design and high revving M powered engine.

The real fun begins when you start installing a few high performance mods to really increase the horsepower - but with all that new power there needs to be an upgrade to stop it.

ECS Tuning found a cost effective option to get our exotic CSL 2-piece rotors on your Standard M3, increasing surface area for greater stopping power. The larger rotor increases the brake torque and reduces the fade - bottom line: consistent, hard braking!
