So now I've picked up my 3MPS which is hands down the best car I've driven. I'm out wheel shopping, how big a rim can the Gen 2's take I've read up on widths and offsets but not much info on sizes. Ideally I want something black which will look smaller so needs to be 19/20 inch but I have'nt seen any cars with 20's. Also i was advised that the 19's would increase rolling diameter by 2-3% will this affect scrubbing much? or is it mainly offset.
