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.
