I have 245/35 19’s on Rotiform KPS 19” ET45 on my 2017 GTI S. On stock suspension, I had no tire rubbing after doing the fender screw mod in the front, and no tire rubbing in the rear. I have BC Racing BR coilovers on it now, and I do get some rubbing, but only at speed going over bumps and dips. The camber is set at 0, and dampening is set 15 clicks from soft, on a 30 way adjustable dampener. With normal driving though, there is no rubbing. I am going to set my camber at -2 in the front, and am rolling my fenders, and that will easily fix the rubbing. Like I said though, even with the coilovers, it is very very minor rubbbing. Normal driving has no rubbing. Sporty gets some runs here and there over bumps and dips. You should be safe with 245’s on 8.5” wheels ET45. The amount of traction is well worth it, over 235’s.
