Seen some 928s with 19 inch rims, think 19s just look like too much rim and not enough tire. Besides, according to a car & driver test going from 18 to 19 you lose .1 seconds 0-60. The main reason for going to 18 from the stock 17 is better tire selection. And with better tires you can overcome the upsize 0-60 loss with rubber compound.
The lift kit thing has been done...
So has the pickup bed thing...
