I'd like to get some new wheels for my 991.1 GT3, and put the GT3 wheels on my 991.2 Turbo S. Methinks they should fit, but I think there's some difference in the offsets. I was wondering if anyone here has tried this,

 

I tried, as I wanted the look of the 991 GT3 wheels for my 991 Turbo S.

They fit, but the rear wheel from the GT3 sticks out a little too much in the Turbo S. It is fine with the 305 PZero tire, but it rubbed with a set of Trofeo R in 305 on a track day.

Official specs:

991 TTS: 20x9 ET51 and 20x11.5 ET56
991.1 GT3: 20x9 ET55 and 20x12 ET47 (the rear wheel will stick out 15mm more in the TTS)

 

Can I get first dib on your .2 wheels if you're doing it?

 

Thanks for the intel. If I do go forward with this, I'd keep the stock wheels. I've found that when it comes time to trade in the car, the dealer wants the factory wheels it came with and could care less about any other wheels for the car. I guess to do the CPO warranty everything has to be as it left the factory.

 

I considered it for a while. It will work. But the fronts will be very tucked. I didn’t like the look. If you could find an RS front, the offsets work better. Your reads should be ok. A little poke, but not too bad IMO.
