In the interest of future knowledge, who sells the harder rubber versions, what sort of cost, and how hard are they to install?

chris walrod

I believe Elephant Racing offers these.

Thanks Chris. After installing two of your kits I would find it hard to imagine the rubber ones could be any better. The transformation in road feel and responsiveness is excellent and I've not noticed any increase in harshness.

chris walrod

Thanks for the nice words!

Here is a link to the rubber bushings:

can these be installed DIY with standard tools or will need a press or special tools?

chris walrod

For the rubber bushings, a press is needed for installation.

Chris, Would the warn front control arm bushings give you a shimmy at 55? I have had my wheels balanced 3 times and they are perfect and true. I put a large screw driver between the frame and the front part of the control arm and there is more play that I would thik there should be. BTW 46,000 miles.

Thanks , Mike

Oh, BTW....still in limbo on the tranny...House has not sold... argggggggg

Hi Mike, Actually, yes -- this is the primary symptom -- also random brake pedal judder is a secondary result of torn or cracked bushings.

As Chris says Elephant Racing has the rubber bushes for front and rear

I pressed mine on(only the fronts, oe RS was used in back) w/ a bench vise & socket.

The thing about rubber and what may be causing an issue for all of those that have lowered cars is that since the rubber bushes have no moving parts they must be indexed to the ride height. If stock rubber bushes are not reindexed(and nobody does) then they will be stressed beyond their design limit and will subsequently deteriorate much more rapidly

Just something to think about on a lowered car.

chris walrod

Bill brings up a great point and one that is overlooked often. Once a ride height change has been made, one needs to loosen the front wishbone mountings, set the car at ride height and re-tighten. Technically speaking, the same should be done for the rears when using rubber bushings.

There is stored energy (i.e. additional and unwanted spring rate) in the bushings once a ride height has been changed, in a static state. Dynamically, there isnt a way to get around the stored energy in rubber bushings.

That works for the rear arm bushings, but on the front control arm the rear bushing is keyed to the subframe so it cannot be adjusted to match a lowered car.
The RS front control arms come with the bushing inserted at a different angular position to accomodiate the lowering.

That's not an issue w/ the Elephant bushes

chris walrod

It can actually -- only because the femal slot is much larger than the male tang and at that pitch radius, not much room is needed.

Thanks Chris.... Can you PM me with the cost of exchange arms for the TT?
This will now be on the list..
