I have not touched any part of my suspension or rims yet. And yea it has scraped before. If i get springs and shocks like you say it weill scrape all the time. If it scrapes occasinally now imagne how bad it will be with the car dropped and a body kit? I want air so I don't tear the crap outta my body kit. Whenever i need to drive up my drive way or over a bump i can jsut "air up". Seems liek the perfect solution to me cept for the highway driving thing. Why would it bounce like that?
