AAF E46 Transmission Crossmember/Transmission Brace

Ideal for the SE46 racing series, the AAF E46 5-speed Transmission Crossmember is a heavy duty and worthwhile upgrade.

The OEM thin cast aluminum cross member has been known to fail in multiple different ways. Firstly, especially when using stiff engine and transmission mounts, the cross member can crack and break around these mounting points. Secondly, the cross member can break from the high amounts of load transferred through the drive train. Chassis flex from hard cornering is being applied through the engine and transmission from the front cross member, and this load is sent from the transmission back into the chassis at the transmission cross member. This is simply too much stress for the OEM cross member to hold up to under the extreme punishment of road racing.

While the OEM piece (22312229198, 22316769911) is made from less than 1/8″ thick cast aluminum at the transmission mount points, the AAF E46 transmission crossmember is completely manufactured from 1/4″ thick heavy-duty aluminum plate. It is designed specifically to cope with hours of endurance racing.

Don’t forget to pair this with our high-quality engine and transmission mounts!

Fits ZF and Getrag transmissions.

Now available for 5-speed non-M, 6-speed non-M, and 6-speed M!
