[W126 Coupe] Emailing: 500 SEC 02.07

[Divov]

As the rubber bush distorts under load, the rear wheels will move fore or aft depending on accelerating or braking.
I have just road tested the car with the aluminium mounts and on the public road I cannot say what has changed handling-wise.
I can report that it is noisy and you wouldn't want that in your road car.
For track use, damn the noise if it helps the handling - that I will know on Saturday.

The whole object of the exercise was to make the antiroll bar more effective by eliminating the rubber distortion. The wheel stability is a bonus.
I'm trying to counter the "designed in" under-steer characteristics and get more over-steer. I want the rear wheels to do a fair share of the work load.

  If the rubber bushing causes the car's rear wheels to toe in upon acceleration, are you concerned about rear wheel stability or are you adjusting the rears for more toe in?

  I've put a liberal amount of copper-slip in the joint.

  Looking at my oe part, there was a fair amount of rubber transferred on to the antiroll bar. (lack of lubrication)

  I haven't road tested the car with my mod as there is still a bit of assembly outstanding but I am racing this 

  week-end. My guess is that my mod may be a bit noisy for road use. A urethane bush replacing the

  oe rubber would probably be a better fix for a road car. The trick is going to be to get someone to 

  make up a batch... The easy way is replace the oe bushes with new ones and apply rubber grease.

  I am convinced these bushes do a critical job, more than just locating the antiroll bar.

  On many cars (Camaro etc) you can run them without an antiroll bar in place. You most certainly can't do that on our cars.

    The mod looks great. 

    How will you keep the aluminum billet lubricated?

    Do you know if there are there any aftermarket urethane bushings available?

    There is a company called "MetalRubber" in California that will re-rubber any 

    Metal to rubbler bonded pieces. I believe that they also work in urethane. 

    I used them for  no longer available Saab part a couple of years back.

    That's the oe rubber bush.

    I shall try and send the modification by separate e-mail. (I'm too dumb to combine the two!)
