Edited my post for clarity.

I'm sure the Whiteline Roll center kit works just fine with this, I can't forsee any issues.

Jeff-

I'll talk with RCE tomorrow to see if it's worth testing these in delrin.

Do you have a picture of the stock bushing?

I'd like to see if there is a bushing sleeve in it stock. We may be able to make something like this work. I'll email you and Andrew privately to discuss further.

P.S. You'd love my car, I've got a sh*tload of Perrin parts.

It'd be a safe bet to realign the car after installing these.

The stock bushing doesn't really have room to put a urethane spacer or anything in it. And making this part out of urethane would hinder some of its axial motion. So it has to be super soft rubber, or a spherical bearing of some sorts.

The alignment is needed because of how we add caster. The bearing is offset, and when installed causes a toe in/out change.

From the Solo Rules for SM:

"Subframe bushings may be replaced with bushings of any material
as long as they fit the original location. Offset bushings may
not be used."

So SM can use ANY bushing material but the can't use the offset. STU can use the offset but metal content may not be more than stock... Crazy rules.

Oh well. I guess I just have to learn to drive better. LOL

So we could make some with zero offset. This would be easy and satisfy some of the AutoX guys.

Steering Precision kit replaces the bushings holding the steering rack. it also looked like the rack moved up slightly after installation, but i cant be certian as i didnt measure

i believe this replaces the rear bushing in the front lower control arm. i am running the energy suspension poly bushing in this location & the diffrence is definatly noticable

the bushings replaced in the perrin kit are not sub-frame bushings
