No. Actually, it's the other way around. Heavy rear weight bias makes for excelent turn-in characteristics when braking to a corner (you can carry a lot of speed) whereas under acceleration the car will naturally understeer as the weight shifts rearward and downforce on the front wheels is decreased. See the above vid when Tiff says 'Wait for power... wait for power... wait for power' while pushing the Cayman because it will also understeer.

The Cayman's factory fitment is 205/55/17 front and 235/50/17 rear which is ok for the 265hp even without the optional LSD.

It's not for chance that Porsche will only allow the fitment of the LSD from factory with 18 and 19" wheels.

Yes. One thing called economy of scale. That's the reason why this car is a joint-venture project between Toyota and Subaru.
