I am swapping my 99 GS-R blades with my friend for his 17" Racing Hart C2's for about a week (he really wants blades). Having the 17" rims seem so big to me, but maybe its just cuz I'm used to the 15's...I know the blades are 16 lbs, anybody have the specs on the 17's? I tried looking up on the internet only specs I could come up with are 18" c2's that weigh around 21 lbs. Don't really notice any difference in acceleration on the streets, but as for performance, I notice more traction off the line. Any help would be appreciated

 

The reason you feel there is more traction is because the C2's are probably a 7 inch wide rim, where as the blades are only 6 inches wide. Therefore you have more contact patch on the ground, cauing you to have more traction.

And i tried searching for the weight of the 17 inch C2's, but couldn't find anything. I only came up with the 18's and like you said they are 21.5lbs.
