Without doing any measurements myself, is it possible to have a +40 in the 9" with 255 without it hitting the struts? My car is a standard GT and trying to avoid modifying it to decrease comfort (already have a modded R32 GT-R, which I used to daily at one point with 265/35/18's and TEIN coilovers, was painful on Sydney's shitty roads and traffic).
I don't mind rolling the guards, but would like to avoid any more modification.
Yes, I'm after max tyre width under stock guards hehe. Have 275/35 under my R32 on 18x10+20 wheels, still a tad too much stretch for my liking (Hankook Z222 tyres).
P.S. those mud flaps work very well visually (and I'm sure practically too).
