Higher power, sticky tyres and longer sessions create more heat, more pad demand and less braking consistency.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe supplied rotors and pads are inspected ex-BTCC components.
