I have a 1997 Jedda GT 2.0 8v, with 17 inch rubber rollers. How far should I lower the car without tire rubbage? Can 1.5" be done without any problems? I don't want to roll the fenders, and I never have more than me, my wife, and my baby boy in the car. Any ideas? Also, where is a good place to buy a set of springs. This will be done for looks only, I'm not a racer.
