The E46 M3's S54 is one of the most responsive naturally aspirated engines BMW ever made. Its braking system should match that level of feedback — and stock rubber lines are the limiting factor. Goodridge's G-Stop kit replaces every rubber line with braided stainless steel, eliminating line expansion and delivering a firm, consistent pedal whether you're on a canyon road or a track day.
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.
