The TMS carbon brake backing plates are made of pure carbon and high temperature resin. Our unique design specifically for the E46 (and non-m Z4) is optimized for 3" hose and allows the air to flow directly to the rotor with no impedance, with a considerably lower weight than competing products. When flow tested compared to a competitor’s product, the TMS ducts flowed twice as much. This greatly reduces the chance of brake fade, boiling the brake fluid, and wear and tear on your brake components. Installation is easy, as it does not require removal of the wheel bearing. We do this by making the backing plate in two parts. The main backing plate and a block off plate that bolt together. Most companies just have a big slot so you can slide the backing plate on, but then it just lets air flow right out of it. We block off the hole to maximizing brake cooling airflow to the center of the disc.

These brake backing plates can be used on the the following BMWs:
1999-2005 E46 3 Series Sedan 323i, 325i, 328i, 330i
2000-2006 E46 3 Series Coupe 323Ci, 325Ci, 328Ci, 330Ci
2001-2006 E46 M3 coupe & convertible
2003-2009 Z4 Roadster/Coupe (non-M) 2.5, 3.0 & 3.0si
