Downside of a larger diameter wheel is more rolling resistance, harder to get heat in them and more unsprung weight.
More rubber (in either direction) = more grip.

Gotcha. With the awd 997.2 (like the gts you drove) there's a "trick" to fool the electronic clutch to force the car into rwd. I haven't read about it recently but putting the ebrake into the first "click" would do it.

Probably won't work on 991s given they now use elec. parking brakes

It's only hard to hold these cars in a drift if you are relying on power to do so. Integral to a nice drift is sufficient momentum.

so much for journalist saying the steering is dead.

Sure as heck looks like an amazing improvement to me.

But the shape of the contact patch determines the performance characteristics. Generally a performance tire will have a wider shorter contact patch for lateral grip for cornering while a taller tire will have a narrower but longer contact patch which will benefit straight line stability and responsiveness.

Regardless the unsprung weight of the wheel and the tire increases negating any benefit of an increased in size of the contact patch.

I quite enjoy all the comments about the new 991. It seems that the sky is falling, just as it did when the 930 became the 964, and when the 993 became the 996! I'm in California on holidays, saw the new car at the dealer a long time ago. It looked nice. Went back to the dealer when the 991 was in the Showroom with 997's. Couldn't tell which was which from the front. Had to walk around the back to see the spoiler to tell the difference!
I'm not bothered, I'm so happy with my Cayman S after years of 911's. I do think Porsche engineering has done a good job of detail work to make the car handle better, despite the electric steering!
