SO it is desirable if fitting wider wheels to try and find relatively lightweight wheels and tires.
Caymans come with lightweight forged rims among other stock features that enhance performance.

you're thinking acceleration from standstil
the drag due to friction is what's gonna slow the car down in the straights, too much straightline grip, the actual weight will become somewhat irrelevant for accelration at over 100mph
