massive - performance brakes exclusively for BMWs

brake systems for the track

We design our brake systems for the harsh track environment around 4 and 6 pistons calipers, using thick 1.25" (32mm) rotors to improve brake cooling and avoid fade, while our competitors use only 28mm rotors with 16mm pad thickness. Our race calipers use full size 20mm pads.

Will the kit fit my wheel?
For checking if a kit fits your wheels, download the profiles in .pdf format. Profiles can be printed on 8 1/2" x 11" paper and test fitted against your wheels. Be aware that the e30 318-325 kit requires race wheels with a lot of room behind the spokes (Kosei K1, Team Dynamics Pro Race).

1. Print the profile
2. Cut it out
