To the eibach users: Anyone have any ground clearance issues with speedbumps with their stillen or borla exhaust? I'm very tempted to get the stillen exhaust next week since the stillen bucks promo is going on where you can get $125 in stillen gift cards. I would maybe get the hawk ceramic rear brake pads with that money. Too bad there aren't any front brake pads either. On a separate note at what mileage are you changing your brake pads? Just the rear pads?
