Brake cooling ducts are a common practice in motorsport. Severe braking conditions create a tremendous amount of heat at the brake pad, rotors, calipers, and wheel bearing hubs. Under normal driving conditions this heat dissipates during the non braking cool down period.

On the track or hard road use the braking is much more severe and the cool down times are much shorter. As the braking temperature increases, brake component service life is decreased dramatically. A standard set of brake pads and rotors can wear out completely during one weekend of track driving. This is due to the material failure of both the pads and rotors at extreme temperatures. Forcing air directly at the core of the brake rotor, which then passes through the rotor vents, will increase the life of the brake components. The cooling ducts direct the air to the center of the bearing hub and brake rotor. The air is then expelled through the ventilation slots in the center of the rotors.

The backing plates in this kit mount behind the brake discs and are connescted via ducting to air ducts mounted at the front of the car, thereby "force feeding" air to the center of the discs to vastly improve heat dissipation and thus help prevent brake fade.

- 2x Backing Plates

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

Brake Cooling Duct Race Kit is THE ONLY complete package that you need for mounting the plumbing for brake ducts to your E46 M3 or Spec E46 Race Car. Our race kit incorporates a powder coated aluminum tube between the inlet and the flex tube where the contact point of the tire would be. This prevents you from instantly wearing a hole in your very expensive to replace flex tube.

SUITABLE FOR BRAKE DISCS UP TO 355mm. This version kit has silver colour backing plates.

Our kit uses a powdercoated metal bracket that mounts to the frame of your BMW M3 which allows removal of your front bumper while leaving the entire kit in place for fast track repairs. No need to fumble with bolts, screws and duct clamps, or unintentionally ripping our your flex tubing in the process.

Our quality ABS molded duct inlets are designed to endure the rigor of racing while saving you hundreds of dollars on your build budget! They're even lighter than expensive carbon fiber and resin alternatives.

This kit requires you to run a E46 M3 Style Bumper. (may work with ZHP and MTech2 bumpers)

PLEASE NOTE : Removal of your your washer fluid tank and AC plumbing is required. If you want to retain these item please check out our STREET DUCT KIT, featured elsewhere on this web section, as well as related items as follows :
- Backing plates on their own, various sizes
- Fog replacement brake ducts on their own

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.
