Those Cayenne wheels look like the Cayman S IIs that I bought. In real life my wheels are more 3-D than I expected. The rears almost concave and the fronts convex (like those Cayenne wheels, they stick out).
I went overboard, grabbing specs for wheels and tires. Going from the 17s to these 18s I lost weight in the rear and gained less than 1 lbs at the front.
This combo should weigh around 42.2 lbs front and 45.3 lbs rear. These are based on actual rim weights and the manufacturer weight for tires.... so who knows!?!
