The natural enemy of braking performance is heat. When temperature levels reach critical levels, a thin layer of gasses actually prevent the brake pads from making complete contact with the rotor friction surface. The addition of cross-drilling the friction surface promotes the evacuation of these gasses and improves stopping performance and pedal feel. TMS cross drilled rotors and AXXIS brake pads result in improved braking performance and look great too!
All TMS cross drilled rotors are made to exacting standards by the worlds leading brake manufacturers. Each part is then analyzed for its specific application and design. Engineers then determine the optimal drilling pattern to maximize stopping power. These patterns are then cut into the rotor using today's most advanced CNC machines. This level of quality control ensures that each TMS High Performance rotor will perform to the highest levels every time under all driving conditions. All TMS cross-drilled rotors feature counter-sunkholes that reduce stress risers and fractures.
Available for the following BMWs: (click icon to change BMW)
Cross-Drilled Brake Rotors - Front - E39 540i (up to 3/00), E38 740i/il, E31 (pair)
(more info) Direct replacement FRONT cross-drilled brake discs for the E39 540i, incl Touring (up to 3/00), E38 740 -12/00, 850 -8/93, 850CSi These rotors feature a unique black electro-coating that is designed to prevent corrosion. Each rotor is e-coated then double-ground and balanced to ensure an even surface with no vibration. The e-coating is the best anti-corrosion protection currently available in replacement rotors. Most aftermarket rotors are not coated, allowing surface rust to form right away, which is unattractive when brakes can be seen through your wheels.
A cross-drilled rotor helps to release gases that build up between the rotor surface and an out-gassing brake pad. Without an escape, this thin layer of gas will cause a delay until the pad cuts through gas layer. The holes in our rotors allow the gases to escape, giving better braking performance and a sportier look.
This item fits the following BMWs:
1997-3/2000 E39 BMW 540i sedan & wagon
1995-2001 E38 BMW 740i 740il
