Has anyone run 991 GT3 RS OEM Wheels 20/21" Aurum Gold GT3RS 911 991.2 Centerlock Center Lock on their 991.1 turbo S. I like the look but don't want to mess up the AWD system with offset numbers. Anyone have any personal exp with this set up? thanks

I ran a 20/21 aftermarket wheel set up on my turbo without issues, you just have to adjust the tires size to make it work. Below are the specs i had if that helps-

20x 9.5 fronts ET 50 with 255/35/20
​​​​​​ 21x12.5 rears ET 48 with 325/25/21

Thanks, I was hoping to just swap with stock GT3RS wheels.

You can, but you'll have to run different sized tires than the GT3RS sizes. The 3RS 325/30 rear tires are too tall for the turbo AWD system. 325/25 is what you'll want to run.

For proper offset you need to run GT3 RS fronts and GT3 rears. The GT3 fronts will be too far inside the front fenders.

This is so important - I wish I had known this before. I ended up using axle spacers to push out the front GT3 spec wheels by 10mm, but I still think about buying two front GT3RS spec FI-R wheels.

I swapped out my original CL carbon fiber wheels for these GT3 wheels. No problem with fitment.

Except that the fronts have the wrong offset and are too far inboard of the fenders. You can see it clearly from your picture.

Shoot a pict from this angle on your car.
