I need help with fitment options.
Lowered with stock wheels and tires. Then ordered these BBS with 295/30/20 on rear. Rubs only when I accelerate hard or hit bump. Options please. 285 does stretch the tire and probably won’t completely correct issue with the offset. Should I raise with adjustable springs?

Strange, you must have purchased an aggressive offset for the rears. I ran the same set up with a 20x11 ET40 and had more than enough clearance while lowered. Do you know what offset? If too aggressive the most realistic option would be to raise the car otherwise customize the wheels which isn't very cost effective.

Please excuse my ignorance. Supreme power set me up with them. 20x10 et 20 pfs5x120

By any chance are you running a spacer? If not, looks like a slight camber adjustment might do the trick.

Ya that's a very aggressive offset. Here's some additional ideas:

-Move down to maybe a 295/25 or even a 305/25 to gain some sidewall.

-Add ~2-3 degrees of camber

-Roll fenders.

-Raise the car.

Can’t roll fenders. Is what tech says.
To raise. KW has adjustable springs.
Neg Camber is also doable. Tech says it will need to raise a little with slight camber adjustment. Just hoping someone else has gone through this and had a sure fix. Eric at supreme. Does this fitment with no problems. Not sure why it’s different with my car.

I have the same wheels with a 285 PS4S. Lowered on KW HAS on the lowest setting in the rear. 295 might be a bit too wide for this offset
