If you want to keep your BMW completely stock, down to the brake lines, we have factory brake lines available. However, if you're looking to improve the feel of your brake pedal and prevent brake lines from expanding when under stress, we highly recommend our Turner Motorsport BMW stainless steel brake lines.
Located at the rear caliper, fits both left & right sides. Replace your old brake hoses before it's too late. A common failure piece after my years of being exposed to the elements. Priced each.
