Tires are good but the brand ive never heard of it before.

For anyone looking to give a hand at solving this, these are his alignment specs (I'm uploading them for him).

Alright, I'll ask it. What are your tire pressures at OP?

Brzlimited661 · 02-06-2018, 06:13 PM

40psi front and rear

I bet the problem goes away when you set them to 35 psi front and rear.

Does this happen turning left and right? I know most offramps are right turns but Im wondering if the caster plays a roll since its so far off? Im kinda a suspension noob and just thinking out loud though

Tire pressure didn't help

Are your rear tires sitting in the wheel wells evenly when you look at from the rear. Are you sure nothing is shifted / bent? What was damaged in the accident?

They do. What was damaged was the front suspension slightly. They needed a camber bolt to get it within specs.

But at least you're now at recommended pressures.

How are the sway bars? Everything look ok on them? Maybe the front sway bar yielded in the accident and now your rears are trying to do too much work?

Thats true thank you
Ill give the front sway a once over i only checked the rear since i thought the problem would be in the rear.

Then it most likely still has something tweaked in the front, which could definitely affect the cars handling.
