Any interest on some Racing duty thrust arm bushings?
I am talking for the Pure drivers who want their E34 to react as soon as they turn the wheel.
Full metal/metal bushing with grease nipple. We could also do excentric bushings for more or less negative camber.
Expect some road noises being transmitted.
We have a set that is on test on a BMW E34 535i turbo on the race track.
So far we experienced with a lot of urethane bushings and none was satisfactory, but the metal bushing is great.
Keep me posted if any of you guys are interested.

I am aiming around 160 - 200US for the set because it will be a limited production.Originally Posted by Incantation
They will be sold as a bushing alone or bushing pressed into the arm (for extra money).

I'm interested. The ride teeth shattering?

Excpect some noise being transmitted but the ride should be the same.
The reactivity of the car while turning will be very quick as there won't be any compliance in the bushing.
There shouldn't be any more bushing to change neither as this is the ultimate radical bushing.
I understand that this bushing won't be for everyone but only the hard core E34 drivers that are going to the track and are tired of changing bushings every year or 2 years (like I used to do).

Bruno,
Would this be a "final" bushing. (i.e. it wouldn't wear out in normal conditions)? Would the non-compliance of the bushing negativly affect the rest of the suspension (control arms, etc...)

The arm is design to flex ( I will have to make a drawing at some point) at the point of the bushing up and down but also a little bit side to side.
I will remove the flex side to side, it will move only up and down.
This won't affect the rest of the car, but the car will react quicker from steering inputs.

Do you have any pics of the bushings Bruno, how to they compare to RRT control arms?
Major Contributor
The RRT control arm is mainly the ball joint. I won't touch that.
I am mainly concerned about the play and the wear on the Thrust arm bushing.
We didn't take any pictures but I will try to get some ASAP.

sorry Bruno. I thought the balljoints on the RRT arms where stock and the bushing's where a spherical bearing type. Here's a pic
