Rated M Roadster compared his OEM wheels to his new 21" Forgestar CF10 wheels w/Michelin tires and came up with a total savings of 89.8lbs!
This made me curious, so I weighed my BBS wheels w/Pirellis.
BBS SV weight savings over OEM M299:
I came up with a difference of 40.6lbs combined unsprung weight for all four wheels and tires compared to the OEM setup
Combined weight OEM M299 20" w/ Bridgestone RFT....82lbs front and 89.8lbs rear.
Combined weight BBS SV 22" w/ Pirelli.......................75lbs front and 76lbs rear
Combined weight Forgestar CF10 21" w/Michelin..........61.6lbs front and 65lbs rear
Gixxer - Somewhat disappointed that his weight savings was not as significant as Rated M Roadster, but he did go from a 20" wheel to a 22" wheel...
