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

The Turner Motorsport Racing Brake Duct Kit for the E46 M3 was developed for our Grand-Am and SCCA T2 M3s. Our brake cooling kit is complete - scooping air from the front bumper, through silicone hose, and to the brake disc hub via backing plates. The front ducts and backing plates are made from 100% carbon fiber for light weight and strength.

These carefully designed spoiler ducts are shaped like an "accumulator box" - scooping the air as it flows around the bumper. Because we make this from carbon fiber we were able to refine the shape and fitment to maximize the airflow, as well as engineer these to be very light weight and use a minimal amount of hose. They can also be custom trimmed to fit a variety of E46 bumpers and configurations. Because this duct was designed for all-out racecars, removal of the factory washer bottle is required.

The hose we use is a high-strength, 3" silicone hose, and strengthened with wire. High-quality hose clamps are included to attach to the bumper ducts and backing plates.

The carbon backing plates are one of our best sellers. These backing plates fit easily onto the back of the rotor without removal of the hub / wheel bearing. The 3" inlet is smooth and unobstructed, allowing as much air into the rotor hub as possible. And since these are made from carbon fiber they are light weight and will not attract/retain heat.

This brake cooling package fits the following BMWs:

- 2001-2006 E46 BMW M3

- 1999-2006 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi,
only with the M-Technic II, M3 style, or ZHP style front spoiler. These will not work with any other non-M stock bumper.
