I recently purchased some Rpf1’s (18x9 et35) and i’m running 235/40/18 dws06+. I had some rubbing on the rears and I stiffened up the dampening on my coilovers. However, with passengers in the back I still rub over big bumps. I am wondering if anyone has some advice on how I could improve this problem. I didn’t realize the fitment would be this aggressive. I’ve added -2 degrees camber to the front but i am concerned that adding camber to the back may harm my tires. Should I look into selling the wheels and getting a less aggressive setup? This is the first car i’ve modded and I would appreciate any advice.
