I can't even UNdrill my head to think about your query if you're serious. I don't think anyone out here (your there) would even dream to lift these cars. Sorry, we're all in the LOWERING camp. And your installer - telling you to lift the car for a better ride. What's he smoking - send me some. Maybe he has a coil over his head. Oh, and what is a 35 tire or a 37 tire? Stop drilling your head for a sec and help me figure that one out ...
