Im planning on buying new rims for my audi a4 b5 and I don't think there gonna fit without rolling my fenders. The rims are 18x9.5 and the offsets I can choose from are 30 22 15 12 0. Im riding with a two inch drop atm and plan on dropping my car another inch. What offset and tire size will work for my car with two inch drop as well as 3 inch drop. I doubt the 3inch drop will work at all without rolling fenders but can I please get some advice >.<
