There was actually a post a little while back of someone who installed some really nice looking $6500 magnesium wheels that weighed less than the OEM Carbon Fiber wheels. I believe the magnesium came in at 16.8pounds which is less than the OEM Carbon Fiber. This is the route I will be taking eventually for even more unsprung weight.Well! Already have cup 2 tires on the car so 12000+ 57000= 69,000 4500 miles on the car I have not seen an R with those miles under 75,000. The Carbon fiber wheels are great but not in a hurry to drive on 3 to 4 thousand dollar wheels and get them damaged
Many r owners store the factory wheels.
Just my thoughts!
