Hey guys. I'm gonna be dropped on unrevised Z springs in a week or so. I know the wheel/tire calculator says to go with 235/50/17 idealy, but how much different will the spedo be if I went with 235/45/17s? If not much I would think to go that route. Seems like 45 series are the ideal sport sedan size, and will handle a bit better but I need some feedback. Anyone running this setup? Any info is appreciated.

 

thats what i run and it is about 2 mph faster when you hit 100 your really doing 98...im not sure if its the same through out the whole speed range. 50 sidewall is just way to big looks like a freaking camery....

You will be fine though dont worry 235/45/17 is great!

 

Thanks Nismo G. 2 MPH is nothing to sweat, I think
