I wrote a little review after I drove a Cayman S last spring...

I think the Cayman S is "slowed" by the fact is less power then a 911, and not as aggressive of a differential.... ratios may be taller, but for the car, they feel perfect... but I think its just the fact that the S has 295 hp, and the 911 has 320... which does make a difference, particularly from 80-vmax...
