Koni's did the trick for me ... I was rubbing the fender in the back forever when I got my 18's, until I got the Koni's and made it a stiffer ride. Now, I do not rub on anything. I'd also recommend getting the Ground Control Coil Over kit so that you can customize your ride level. This combo worked wonders for my suspension department, and the car looks fat as hell now.
