when you lower your car on 'big' rims, the top of your wheel will be more likely to hit the edge of the wheel arches. feel under there now and you will feel some metal, rolling them means, rolling this metal back so there's less chance of hitting when you lower it / go through pot holes.
VIP look aye? you shoulda got a VIP car then like an Accord or Oddysey? I always thought the integra was a Sporty look?
