Given my shaming (see above). I think I will change my mind and go with 255/35/19 and 275/35/19 PSS's.
My only concern is potential rubbing at the front. I am going with Eibach springs. I am also getting the Avante Garde ZHP M359 reps, as the front 19x9 offset is 18 ET while the factory front offset is 31 ET. (I am going with these as I do not want spacers).
It looks like some of you guys are running 12mm spacers on your front OEM ZHP's, that is the equivalent of 19 ET, correct? And those guys seeing any rubbing with 255/35 with that setup and being lowered?
