The F8X platform's carbon ceramic brake option signals who Goodridge designed this kit for — but even on steel brakes, stock rubber lines are the limiting factor in pedal feel. Under hard driving, factory lines flex and expand, softening response mid-corner. The G-Stop kit replaces every OEM rubber line with stainless braid and PTFE, eliminating expansion and delivering a firm, repeatable pedal through a full track session.
Goodridge G-Stop brake line kits are direct bolt-on replacements for all OEM rubber brake lines, with hose ends and brackets engineered to match factory mounting points. Every kit is US DOT certified and TUV approved, and all lines are pressure-tested to 3,000 PSI through Goodridge's 9-point quality assurance process.
