Transmission Brace, AAF - E46 M3 6MT

The AAF transmission brace replaces the thin cast aluminum brace with a thicker and reinforced aluminum brace. As a true race-developed part this brace design has been properly reinforced for the typical loads and forces from solid motor and transmission mounts. The factory cast piece is known to crack or deform from serious track use. The more rigid brace reduces the changes of mis-shifts too.

This is Made in the USA and a proper upgrade aimed at track use.
