: Hard to account for some differences, there can be so many factors. Are your rear tires 235's? That's definately not going to help 60 ft times. : Good luck on your coolant leak. well actually the rears are 18x9 wrapped with 265/35/18. What I am saying is, is that normal for a stock TT 300zx. It just seems very slow. I have seen guys run high 13's.
