2. Yes, but the GT4RS also runs on narrower tires. 

Do you know tire sizes of 4RS? 

By all accounts it's the same as GT4. So 295 on 11 inch rear as opposed to 305 on 12 inch in the GT3. 

They didn't change the rear fender so don't think wider tire is possible. 

 

You think they widened the fronts (this is where more rubber would help, IMO)?

 

Wider front tires is just going to give it more front end grip and making the rear even more twitchy. Existing 245 tire is more than good enough, especially since the Cayman isn't lacking front end grip in the first place. It has more of it's weight up front, unlike a 911.

It looks like the front fenders seems wider than the regular GT4, perhaps it's was for wider front track.
