your E46 M3* to CSL levels of performance is a lot easier and
cheaper than you might think!
In Europe, BMW released the ultimate
E46 M3 badged the "CSL" after one of the greatest performing BMW's
of the 70s. This latest CSL car was completely reengineered on the
Nürburgring Nordschleife, one of the longest most abusive
racetracks on earth. Part of the CSL's reengineered design was
incorporating 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 design to allow the disc to expand evenly
for consistent stopping and less pad 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 co-efficient. This braking system makes a
noticeable difference in brake feel and prevents fade compared to
the stock system. Incorporating this kit with a quality Performance
Friction pad set is the best way to reduce stopping distances and
increase the ability to stay on the track longer!
The kit consists of all parts
necessary for a complete upgrade to the front braking system
including both directional vented rotors, larger caliper carriers,
and rotor retaining screws. Brake pad options are available
including our premium line of Performance Friction brake pads
ranging from performance street to aggressive track. The CSL
braking system uses the same pads as E46 M3s and fits within
factory 18" wheels.
Note: Matching rear CSL Rotors are
Made in Germany

Competition Package. Competition Package cars already incorporate
The CSL braking system.
E46 M3 OEM Front Brake CSL Upgrade Kit.
From HPDE User of SOCAL, California on 11/4/2014.
Purchased the larger rotors due to a lack of availability of the OEM Euro rotor. Slightly larger than the original size they provide greater swept area for the stock calipers. The new mounting bracket supplied with the kit is a work of art. Very nicely machined and coated ! The new rotors, new HP Plus pads, and replacement Z4M rear rotors have the car stopping great. Highly recommended upgrade from the factory that will have your nose on the windshield in a panic stop.
