Well they fit. Have yet to get tires on them. will probably end up being some cheap tires cuz i splurged on the wheels and i'd like to get some lift and a few other things need addressing. They fit on the hub and everything and has about an inch and a half clearance on the back to the upper arm which i assume is good. I've figured out that they are about a quarter inch wider on the inside so i doubt that will cause problems? Oh and my stock 18's say the have an offset of 38mm as well. Any other ideas or input that i may have over looked before i plunk down the money for tires?
