Wanting a 18x9f 18x10r wheel setup am I crazy?

Well I pulled the trigger on some 18x9" w/6.57" bs and 18x10" w/ 7.2" bs Shelby Redline wheels. Wish me luck! Thinkin 265/35 front and 295/35 rears maybe too.....

I am very interested in this combo, as I am doing the same thing. Are you using a stock, 57 1/8" wide rear for your measurments? Any spacers?
