BTCC Big Brake Kits

Explore XC3 Engineering’s range of BTCC Big Brake Kits designed for serious fast road, track day and motorsport use. Built around motorsport-derived BTCC brake components, AP Racing calipers and XC3 precision-engineered mounting hardware, these kits deliver a major upgrade in braking performance, heat capacity and consistency over factory brake systems.

This collection includes complete big brake kit conversions for selected BMW, VW, Audi and SEAT performance platforms. Our BTCC brake kits are designed to improve stopping power, reduce fade, increase consumable choice and support repeated high-temperature braking during hard driving.

Using AP Racing CP9660, CP9668 and CP9449 caliper options, floating BTCC-style rotors, XC3 rotor bells, caliper brackets, braided lines and motorsport pad choices, these kits give customers access to proven race-derived braking performance with vehicle-specific fitment and XC3 engineering support.
