Spiegler G8X M3/M4 Line Kit

Replace the soft rubber brake lines on your G80/G82 M3/M4 with this Stainless Braided line kit from Spiegler The factory G80/G82 brakes are by the best brakes BMW has given a production car to date. However, they still suffer from rubber lines which cause inconsistencies in brake pressure on track and can bulge causing a "spongy" pedal feel. These lines are a great step in the right direction to alleviate this without having to spend for a full AP kit. Better pedal feel Better brake modulation for track and canyon use More abrasion resistant than the factory rubber lines Resists bulging under pressure and heat Works with Standard and Competition package Works with Carbon Ceramic option and Iron option
