Well, it looks like a 4 inch lift is in my future! The only thing I have questions about though, is how much mileage I will lose. With my Helo 20s and 305/55 Nittos, my mixed driving average is 18-19. I was getting the same mileage with my stock 20s and the stock 34" tires also. Should I expect to lose much when I go to a 35?
