I'm looking to pick up a set of these for my AP1. Car is lowered on Espelir ASD springs (~1.3" drop) and the tires will mount to wheels with the dimensions: 17x7.5 et 45, 17x8.5 et 48. Tire sizes would be 225/45R17 and 255/40R17. I'm wondering if I will incur any rubbing problems, especially with these springs and offsets? I ask because the sticky states minimum offset 53mm for 225 tire up front, and min 50mm offset for 255 tire in the rear. So these wheels are close, but don't quite make the recommended offsets.

Those tire sizes best match the stock tire diameter, better than a setup of 215/45R17, 245/40R17.. plus I really wanted to run the RT-615s. If you think I will have problems though, I will start looking for narrower tires.

Stock diameters of my S02s in inches:

205/55R16: 24.9
225/50R16: 24.9

diameter of 17" tires, difference from stock, percent error in speedo if both tires were the same:

215/45R17: 24.6 (-0.3, +1.0%)
226/45R17: 25.0 (+0.1, -0.4%)

245/40R17: 24.7 (-0.2, +0.6%)
255/40R17: 25.0 (+0.1, -0.7%)

As long as you roll the rear fenders and rear bumper shaved a little, you shouldn't have any problems. Fronts i'm not so sure about. I'm running the 255/40 RT615 on my 17x9 +45 wheel in the rears and don't rub. You can see my sig picture to get a reference of how low i am too.

I was advised not to run 225 in the fronts on my 17x8 +45 rims unless i get the fenders pulled a little, so you might have trouble too. i'm running 215 in the front at the moment.

BTW, i just got an alignment yesterday and i was at -2.5 degrees of camber in the rear--which aided in clearance.

Ok so you're running 255/40 and 215/45 RT615s? I assume you rolled the rear fenders and shaved the bump, hence the recommendation? Your car is pretty low.. I do not expect mine to be quite that low (the springs are not in yet), but it should be close. Thanks for the input. Anyone else have experience? thanks
