Regarding the "turbo wheels" question - I would not use them. With so many great aftermarket wheels, why try to make your 997S look like an (imposter) turbo? I also don't like those who use 997GT wheels/spoilers/etc on the Turbo. IMO it simply cheapens the car.

However, it is your car and you should be happy with it. Do as you please.

Just my $0.02. (since you asked).
