If your car did not come with the sport package and you are going w/ H&R's you risk damaging your rear subframe as the stock non-sp shocks will not be able to handle the drop, in turn stressing the subframe. Invest $ in a set of Bilstein Sports or Koni's. You shouldn't have a problem with rubbingbeing that the fenders will be rolled. For further info do a search on rear subframe.:thumbup:
