AP Racing CP9665 Front Big Brake Kit - BMW M2 / M3 / M4 (F87 / F80 / F82 / F83)
This AP Racing front big brake kit is built for the BMW M2 (F87), M3 (F80) and M4 (F82 and F83). It pairs AP Racing's CP9665 6-piston radial-mount caliper from the PRO 5000 R range with Paragon 378 x 36mm floating rotor rings, for strong braking torque, thermal stability and a consistent pedal under track conditions. The CP9665 takes AP Racing's 25mm-thick CP6230D54 pad, giving more pad material than the CP9660 for longer sessions.
The CP9665 is a forged two-piece aluminium alloy caliper with AP Racing's asymmetric design, differential-bore stainless steel pistons (27.0, 31.8 and 38.1mm), high-temperature seals and 7 lb anti-knockback springs. Each caliper weighs 3.1 kg without pads. The Paragon rings are CM-250 high-carbon cast iron with 72 directional vanes and a slotted face, on a 240mm PCD with 12 mounts.
Note: The top tag of the CP6230D54 pad must be removed before fitting. Check wheel clearance before ordering. Kits are made to order. AP Racing's CP9665 installation drawing is available here (PDF). Installation by a professional is recommended.
