I really like the Tree House Racing front control arm brackets and bushing on my car, but it looks like those are NLA, and Bimmerworld now actually has a slightly cheaper alternative--

They also have a bearing set to replace the rear trailing arm bushings. I don't have any first hand experience with these though.

Before I refreshed the RTABs and put in companion limiters, I got a kind of "wiggle" out of the rear end between when the chassis finished rolling and the rear end took a set. Went away when addressed.
Other track related suspension wear issues I've had over the 90,000 total miles I've put on the car are a rupture in the driver's side strut bearing and the inner ball joint on the same side front control arm-- seems to be more right turns than lefts at the track.
Strut bearing issue addressed by installing adjustable camber plates-- not much to do about the ball joint except replacement. |
Great info. Any idea if there are upgradable diff mounts? Since it will all be apart anyway I would like to be able to do those at the same time.
