Newer to the Scion world.... I wanted to do a 17" wheel, but not sure which tire and wheel size combo to do???? at least a 17x7 maybe 225/45-17?? my current suspension drop are Tien S tech spring and AGX shocks, so with the stock steelies, it's a nice drop. I don't wanna change the camber much, but I want it as flush as I can go without rubbing issues... so which Offset is the next question. PLEASE HELP
