Ok I got a good deal on a set of wheels and tires. But the tires are a 215/45/17. The tires are fine on the car untill I fill it with people or hit some nasty bumps. then It rubs. I have a stock suspension right now. I was thinking I could spend some cash and get tokico ilumina shocks to stiffen things up or I could get some correct tires. What do you guys think?
