Here is where I found the PP2 offset info...maybe a current owner can verify?

Hard to image that Ford would make special larger fenders just for PP2's but I suppose anything is possible.

Update to this thread. I installed lowering springs since above picture. The tires and wheels fit well lowered.

Got a reply from a PP2 owner that the front wheels are 19 x 10.5 +24, and rears 19 x 11 +48. Kind of aggravating that the wheel-size.com website published wrong numbers.

So... still wondering if anyone has tried OEM GT350 wheels on their GT PP1?? Looks like the fronts would not stick out as much as the PP2 wheels, but the rears would extend an inch farther in towards the wheel well so I'm wondering if there would be rear clearance issues.

Plenty of inside room at the rear. And rear fenders are the same size for all s550 Mustangs. Fronts are wider for Shelby's. And based on PP2 offset, possibly on 2018+ cars.

GT350 wheels have been reported to work on a GT. But some say you need a bit more camber to tuck the top of the tire so it doesn't poke out on the front (2015-2017).

I can confirm those are the correct specs on the PP2 wheels. And, fender liners are different on the PP2.

The 19x10.5 ET 30 and 19x11 ET 50-62 work as well for those looking for options.

In case anyone was wondering about more exact numbers, I took some measurements to see how much stock GT350 front wheels would poke out on a GT...

My PP1 front wheels are 19 x 9, +45. The stock GT350 wheels are 19 x 10.5, +30. This works out to the GT350 wheel rim/edge sitting almost exactly 1.5 inches farther out than the PP1 wheels.

So I made some 1.5 inch spacers, put one at the top of my wheel and one at the bottom, and held up a straightedge. With my stock alignment and suspension, the GT350 wheel edge would be about 0.400 inches out past my fender edge, so between 3/8" and 7/16".

From pics of the GT350 front wheels and tires, it looks like the tire sidewall slopes back in towards the car, so the setup may look pretty close to flush if the suspension and alignment are stock.

UPDATE: The wheels are installed and everything seems to work great. No TPMS warning lights, although I did confirm that these sensors were 315 MHz before buying the wheels. They only weigh about 2-3 lbs per wheel more than the stock PP1 wheels and tires. The front sticks out a little as expected, although the tire sidewall does slope inwards so the tread itself is flush with the front fender. I used the stock lug nuts too. The car handles GREAT now! I was going to install a bigger front and rear sway bar but now I don't think it's necessary; it's like a go-cart and the steering response is also great. The downside is that it's harder to drive, the front wheels seem to want to turn left and right following road imperfections, but since this is not a daily driver I don't regret making the switch.

So I was looking into a set of 10.5" front wheels but noticed that PP2 offset still pokes. Does anyone have a revised offset (other than the +24)?

Eventually I'd like to run a 305 up front.

Yes, I don't know why the PP2 has LESS offset than the GT350.

Use the +30 of the GT350 and maybe add a bit of camber to tuck them.

Get your hand behind the PP2 wheel and see how much room you have between the tire sidewall and the strut. Its probably slightly more than 1/4”. Anyway thats the room you have to work with if you want an offset to move the wheel inboard.
