The original brake ducts from the EVO3 M3 were a highly sought after upgrade, both for appearance and performance. These parts, however, have been discontinued by BMW for many years, leaving M3 owners with only make-shift and custom options for brake cooling from the bumper. TMS has taken the original kit, made some improvements, and has re-introduced the kit for the BMW market. The TMS kit is higher quality, looks better, and even fits better than the Original BMW kit ever did. All while still retaining a factory Sport Evo appearance.
We have molded these parts from 100% aerospace pre-impregnated carbon fiber and cured in an autoclave for highest quality. Unlike other carbon products, these do not use any fiberglass or fiberglass resin which weakens the final product and makes it heavier. The bumper ducts can be painted if desired for a factory look.
One of the biggest improvements is in the fitment of the inlet ducts to the bumper. The Original BMW kit used spring clips that did not keep the duct positioned in the bumper very well. Other aftermarket kits used a universal duct and required you to fabricate a bracket. Coupled with poor quality plastic ducts the result had gaps, mis-aligned parts, or the ducts falling out altogether. The TMS ducts are held in place with hidden hardware from the backside of the duct. This keeps the duct securely in place at all times and has a cleaner appearance.
These EVO III Brake Ducts fit the following BMWs:
