Hey everyone, I have a few wheel questions.

First: I found some nice Volks on eBay for an Is300. Granted they aren't staggered and only 7.5''w, they are good looking GT-7s. Anyways, they are +40 offset. Is that enough for 7.5W all around? And the tires might be a little tall, I am not sure - 225/40/R18. Will they work?

Second: Looking at some GT-Ps on eBay that come from another S2K. They are 7'' and 8'' wide, both with the offset of +44. Is this ideal? And what are the widest rubbers I can fit on these?

Third: This may sound dumb to some, but I was thinking about Powdercoating some wheels. I currently have mine powdercoated, and love the GT-P wheel but do not like silver. Has anyone powdercoated an aftermarket wheels? Specifically a 2-Piece? Would the wheel need to be seperated first? Just an idea. Please share your opinions!

Thanks!!
