I'm riding on 17" that have been lowered 2.5 in the front and 2.25 in the back. It looks really good and I take corners a little better, but when I ride over speed bumps or rough pavement my wheel mostly my back ones rub in the wheel well. Would I need to get some stiffer shocks to resolve this, if that's the case then what recommendation can be offered. Has anyone else with 17's encountered this.
