Sorry I didnt reply faster, Easter Holiday. Anyway. I cant really see any difference in smoothness. Th car handles 1000 times better though, even with stock tire and rim size, which I must say stinks. Like I said, I bought some Giovanna 17X7.5 Rio chrome wheels and sould be installing them tomorrow (Monday) if everything goes right. I'm sure the ride will be a little stiffer but thats ok, I'm young! Right now, there is absolutely NO tire rubbing, and I have the smallest spring pads on the car. I hope it dosent rub with the new wheels, but if it does, I'll find a way to fix it. Good luck....
