Perrin P.S.R.S. clearance issue - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

15limited · 05-09-2017, 10:06 PM

After installing Perrin offset control arm bushings I've encountered a problem with clearance between the ball joint end of the control arm and the inside of the rotors. Has anyone else had this problem, or could think as to why I might be experiencing this issue? Lowered somewhere between 1 to 1 1/2 inches on Fortune Auto 500's with -2.5° of camber, Buddy club extended ball joints and Perrin poly bushings, stock rotors.

You can see the scoring of the rotor circled.

Not yet, I've only been able to find a couple of threads of people using the part. The forum seems to be the largest wealth of knowledge and much quicker then contacting the manufacture directly.

Huh? I'm not sure waiting for an answer here beats a phone call. I am assuming you are in the U.S. given PNW.

I'm not going to leave the problem unresolved for weeks on end, and I don't usually have time to call them during the day.

When I'm off work, yes. Thanks for the advice.

Where was your camber added? Camber plate, or at the knuckle? If you add a bit of camber at the knuckle (either a crash bolt or slotted upper hole), you'll move the rotor away from the LCA a bit. You won't get a ton of clearance, but enough to not rub.

Yeah I maxed out SPC crash bolt on the bottom which I think was good for about 1.5° and another degree on the camber plate
