Wider tires on a GT3

Tire size
Yes I run MSC2’s 265-35-20 and 325-25-20. There’s rubbing on the L front primarily. It has slowly rubbed a hole in the plastic fender guard near the reflector and now it doesn’t hardly rub. I have not had any significant tire issues that either I or the Motorsports shop I work with can tell. Have done 3 track weekends with this setup and I like it a lot.

Post pictures if you can please.
How much Camber are you running up front?

I don’t have any static pictures, but car looks awesome with better fill of the wheel well. My car is currently being transported for track weekend at Road Atlanta. I have some action pictures from Barber. These are 20 inch CL OZ rims that are same specs as factory 20’s that I am running with the above mentioned tires.

Camber settings are max factory settings which I believe are 2.25fr and 2.5r.

If you want a quick three seconds per lap just drop down to 19" wheels and run Hoosier R7's...265/35x19 up front, 325/30x19 in the rear.

Hard to say... I got the car in July and went directly to this setup. I just did my best time ever at Barber with a 136.06. Perfect conditions and had a passenger in the car. Had a good clean lap. No traffic. Fastest posted time is 135.7. So I think it makes a difference.

+1 Based on my friends experience with his 991.1 GT3 in running this setup it's what I have purchased for my 991.2 GT3 (for when the snow melts at this point). The only additional item is some thrust arm bushings to adjust the front castor. As one poster has already noted there can be some rubbing in the front once you add in camber with the 265's. Easy fix with Tarett thrust arm bushings if needed. Some 19 inch rims will also require trimming the rear control arm bolt. Amazing grip from what I see.

If you have the correct custom offsets from an aftermarket wheel brand like HRE you will not have any rubbing issues whatsoever using the 265 & 325 setup. We've even done 335's in the rear on HRE's with no issue.
