Would anybody know if the stock 997 GT3 wheel fit ; a 997 carrera or 997 C2S. If not what can you do to make them fit. Thankyou for your input.
997 C2 and GT3 are both narrowbodies - slight differences in wheel widths and offsets but the GT3 wheels should fit no problem.

Hi,
were you able to put 997 gt3 wheels on the C2S? any issues ?
Re: Will GT3 wheels fit 997 Carrera or C2S?
I had seen this done on another 997
Finally got around to the install
More than you wanted to know below
Front Wheel/Tire
Stock 19x8 Offset 57mm
GT3 19x8.5 Offset 58mm
Changing from Stock to GT3 moves outer rim out 05mm or 0.2In
Changing from Stock to GT3 moves inner rim 07mm or 0.3In closer to suspension
Measuring actual wheel/Tire setup (Front)
Outer tire face is 1/8In or 03mm further out
Inner tire face is 1/8In or 03mm further from the Suspension
(I know - But that is what I measured)
Each Stock Front wheel with tire mounted weighed 46 lbs
Each GT3 Front wheel with tire mounted weighed 50 lbs
Rear Wheel/Tire
Stock 19x11 Offset 67
GT3 19x12 Offset 68mm
Changing from Stock to GT3 moves outer rim out 12mm or 0.45In
Changing from Stock to GT3 moves inner rim 14mm or 0.55In closer to suspension
Measuring actual wheel/Tire setup (Rear)
Outer tire face is 1/8In or 03mm further out
Inner tire face is 7/8In or 22mm closer to Strut
Each Stock rear wheel with tire mounted weighed 55 lbs
Each GT3 Front wheel with tire mounted weighed 64 lbs
Other Stuff
Total Weight added = 26 Lbs for 4 wheels and tires
The mounting flange on the GT3 wheel is slightly thicker than the stock flange

Quote:Cast wheels are usually heavier than forged plus the GT3 wheels are bigger (more mass) - 8.5 v. 8.0 and 12.0 v. 11.0

The GT3 wheels and tires add 26lbs! Wow! If anything you would have thought it would have been the same, less, or maybe just slightly more.

I didn't know the GT3's wheels were cast.
That's odd. Usually forging (or milling) yields a stronger, lighter well.
There's nothing overly complex about the shape. I wonder why Porsche decided to cast the wheels.
Don't know either - seems like the only 997 forged wheel is on the TT.
