I got the Euromax 612's installed yesterday with some General UHP 255/45/18's:banger: The rims are a 18X9 with a 36mm offset and gunmetal in color. I took pics of the caliper clearance and one of the inner rim to show you non-believers that the calipers DO NOT RUB!!! The best part of going to an 18 is that the General UHP tires are about half the price that the stupid Goodyear 225/45/19's run. The UHP's are an excellent straight line traction tire and I ran them for years on my NSRT. One added bonus is that the ride is much more compliant over rough pavement due to the higher sidewall.
