Our 299X32 4 Piston Front Brake System | Competition is designed for customers who want a more period correct looking caliper that fits under smaller diameter wheels while still maintaining a high level of performance. This system uses AP Racing 4 piston calipers and 299X32 60 vane J-hook friction discs. If you have any questions or need any help with assembling your system please get in touch.
NOTE: Kits are assembled upon order which can add 5-10 days to your order, if longer we will update you by email.
ATTENTION: Installation requires slight trimming of the front dust shields.
Additional Information
Assembled 299X32mm 60 vane rotor weighs 12.5lbs vs 12.8lbs for the OEM E28 535i 282X25mm rotor and 19lbs for the OEM M5 300X30mm rotor. Saving .5-13lbs in un-sprung and rotating mass on the front axle depending on model
Disc metallurgy specifically designed to handle competition duty for long term durability. Mounting hats manufactured from 6061 aluminum and hard anodized to MIL-A-8625 Type III in gray with a laser etched Ass to show proper rotation direction
Caliper and mounting bracket weigh in at 5.5lbs per corner vs 10lbs for the OEM E28 535i sliding caliper and 11lbs for the OEM E28 M5 fixed 4 piston caliper. Saving 9-11lbs of un-sprung mass on the front axle depending on your model
Caliper and all aluminum hardware is hard anodized to handle elevated temps. Paint and powder coating don’t handle the extremes of competition
