Poly strut bushings.

I thought about doing that, my opinion is, it's already creating resistance and making it thinner would just create more. I'm sure yours works fine, not questioning how you solved yours.

It's an arbitrary number, the amount that needs to be removed, since I have not found that number I would just be guessing. I have QA1 upper control arms with heim joint, getting the correct caster, camber etc shouldn't be a problem, it's the added resistance that bothers me. And that I've seen too many people having to replace the Poly bushing. Not wanting to replace the bushing later is more the issue.

I don't enjoy doing stuff twice.
