With a stock width beam you need to watch for wing clearance if you lower it a lot. In my view the rims with most offset are the best choice, the 2l alloys are pretty safe, I think 35mm offset off the top of my head. In my experience the usual empi 8s with 25mm offset is not enough if you lower it more than 1.5". Obviously tyre size/width is important.
