I can't see why Porsche gave the new GT3 a 12" rear wheel while the turbo got the 11"?? You would think the flagship/most hp Porsche would get the widest wheels??

 

I think that GT cars are the flagship even if they don't cost as much. The GT3/GT2 has always had better wheels than the Turbo... And in the GT3 all of the power goes to the rear...

 

are you sure about that.

 

Yes....I have checked a number of sources.

 

480hp to four 11" wheels is much mo grip than 415hp to two 12" wheels.

 

I think the fronts are 8's or 9's.

 

Yeah but they don't get much of that power...

 

The Turbo has a new intelligent AWD system, so don't expect the power to stay in the back most of the time. Torque transfer 100% at the front is possible too or maybe at 1 wheel only

Turbo & GT3 use 19 x 8.5 in the front.

 

The 997TT is an all wheel drive car, while the GT3 is a real wheel drive car. So the porsche uses all four wheels to maintain traction, while the GT3 only has 2 wheels to do so.

 

I think he hit the nail on the head... Smart man.
