You have 17's with 40 series tires?? you know your losing miles right? Your rims with those tires off set your milage, because your wheel set is now smaller then your stocks.
Anyway, I have 18's with 40's and it's the right hight for a body kit, but I don't know if I was any lower. So I don't know about 17's with 40's. I think it will be too low?
just my .02 cents
