Increasing the braking ability of your E46 M3* to CSL levels of performance is a lot easier and less expensive than you might think!

Our E46 M3 OEM Front Brake CSL Upgrade Kit brings your U.S.-based braking up to the high-performance level of the fabled M3 CSL. In Europe, BMW released the CSL as the ultimate E46 M3, named in the tradition of the greatest performing BMW's of the 70s. 

This latest CSL car was completely re-engineered on the Nürburgring Nordschleife, one of the longest, most abusive racetracks on earth. Part of the CSL's design was engineered to incorporate a larger front brake system to increase thermal mass and decrease fade caused from overheating on the track. BMW increased the size of the front rotors from 325mm to 345mm and created a full "floating" rotor design to allow the disc to expand evenly for consistent stopping and lespad wear. 

To offset the weight of the larger size and reduce unsprung weight, the rotor hats are made of aluminum. The OEM disc set is also cross-drilled for better gas evacuation and increased friction coefficient. This braking system makes a noticeable difference in brake feel and prevents fade considerably compared to the stock U.S. system. Incorporating this kit with a quality Performance Friction pad set is the best way to reduce stopping distances, reduce fade, and increase the ability to stay on the track longer!

Our CSL upgrade kit consists of all parts necessary for a complete update to the front braking system, including directional vented rotors, larger caliper carriers, and rotor retaining screws. The CSL braking system uses the same pad sizes as standard E46 M3s and fits within factory 18" wheels, so no other changes are needed. Brake pads must be purchased separately.

Note: Matching rear CSL rotors are also available.

*Kit is not necessary for Competition Package E46 M3s; Competition Package cars already incorporate the CSL braking system.
