Although I agree the difference is almost unbelievable, the merit of lighter wheels is not just in overall mass decrease. Lighter wheel needs less energy to spin up (and require less energy to dissipate while slowing down) ...
Sparoz is the fuel consumption gain is still in effect and from your POV related to the light weight wheels?
OP, nice wheels and in spite of their price: tempting, ... thx for posting.
