With lots of racing years under our belts, the feedback from our team is that most failures in lines occur near the caliper, where the Teflon liner is baked by 1,000F+ rotors radiating heat. To prevent the issue, we have added a protective heat shield on each of your caliper lines that reflects radiant heat, a solution proven through years on our in-house racecars.
As in any performance application, replacing squishy rubber parts with a performance piece will increase response and feel - brakes are no different. Stock rubber brake hoses (4-6 per car) expand under pressure, requiring increased fluid volume and increased pedal movement for a desired stopping force. Constructed using top quality components, our braided stainless lines reduce this slop dramatically.
BimmerWorld V2 lines feature a non-expansive Teflon® center core, surrounded by braided stainless steel for durability and abrasion resistance. V2 lines incorporate a coated alloy attachment sleeve for added strength and chemical resistance. Lines are sheathed with an attractive blue plastic cover for a clean look and to prevent debris from working into the stainless braids.
Line end fittings are a heavy-duty steel with a durable zinc plating. In our years of experience in racing and the performance BMW industry, we have seen several specific failures from typical stainless brake lines. Our fittings are designed to eliminate the common stress/failure point. Additionally, the hydraulic crimping method used in manufacturing our BimmerWorld V2 lines leaves a smooth transition between the filling and line, which is yet further protected from stress and abrasion by a flexible rubber sleeve.
Finally, all of our BimmerWorld V2 lines are tested to at least 3,000psi, and stamped with our DOT approval number. This DOT stamp is the government's approval that our manufacturing process produces lines able to endure rigorous testing that simulates road use. This 3 digit stamp on each of our lines ensures that every line is made and tested to DOT standards, with the DOT stamp of approval - not just "made to DOT standards" or "DOT compliant" like many other brands.
Custom line sets also available, including partial sets to compliment big-brake kits and AN lines for racing applications - please inquire.
Includes replacement M10 copper crush washers.
