Product Description
The SEAT Leon Cupra 5F is a capable performance platform, but repeated hard braking on road or track can quickly expose the limits of the standard front brake setup. Higher power, sticky tyres and longer sessions create more heat, more pad demand and less braking consistency.
The XC3 BTCC Big Brake Kit solves this by combining motorsport-derived 368mm x 36mm floating rotors with AP Racing CP9660 six-piston calipers. The larger rotor size improves heat capacity, while the floating bobbin assembly allows controlled rotor expansion under temperature. XC3-designed bells and caliper brackets ensure correct fitment, caliper alignment and pad sweep on the Leon Cupra 5F chassis.
The supplied rotors and pads are inspected ex-BTCC components. This allows customers to access high-level motorsport hardware at a more cost-effective price point than a fully new equivalent setup. Some cosmetic marks and signs of previous motorsport use should be expected.
