Achieve rock-solid caliper alignment and zero mounting flex with the XC3 Engineering Caliper Carriers for the AP Racing CP9660 setup. When adapting motorsport-grade AP Racing Pro 5000R 6-piston calipers to the front steering knuckles of your BMW F8X, standard universal adapters fall short. Deflection in a caliper bracket leads to uneven pad wear, soft pedal feel, and reduced total braking force.

Precision-engineered and CNC-machined in the UK from high-tensile structural billet aluminum, these brackets position the CP9660 calipers at the exact mathematical offset required to sweep a 368mm x 36mm ex-BTCC rotor. Finished in a durable hard-anodized coating and supplied with ultra-strong high-tensile hardware, they ensure instant hydraulic response and maximum pad-to-rotor clamping pressure.

FAQ

Q: Are these caliper brackets sold individually or as an axle pair?
A: These caliper carrier brackets are priced and sold as a complete pair (left and right front sides) including all necessary high-tensile mounting hardware.

Q: Will this bracket fit the slightly thicker AP Racing CP9668 caliper?
A: No, this specific part number is machined with the exact radial depth and mounting offset tailored strictly for the AP Racing CP9660 caliper running the 368mm x 36mm ex-BTCC rotor layout. Please check our other listings for alternative caliper applications.

Q: Is modifying or grinding the factory front hub knuckle required for installation?
A: No. These brackets are designed as a direct mechanical bolt-on upgrade, mounting directly to the factory BMW front steering knuckles utilizing the supplied high-tensile hardware.
