not reading 6 pages, so this may have been said, but changing the offset, will throw off your alignment my car came with +40's on it, and there was nasty camber, switched to the Mz3 wheels 52.5 offset, no camber wear issues. same with my snow tires which I believe (but don't really care) are 50 offset. I'll be running FDs with 3mm spacers (I think) next summer, for a 47 offset when all said is and done. you CAN run whatever offset you want, but anything below 42 (so anything over a 13mm spacer) on stock size tires and you'll probably be chewing on tires with your fender unless you roll them.
