I wonder what's lightest, Bbs chr or oz ultraleggera ?

 

The 0Z's are lighter but the offset would have required me to put 18mm spacers in the rear just to match the stock Porsche Sport Techno wheels "look" in the rear. Keep in mind the CH-R's like the Sport Techno's are both 11.5 inches in the rear the OZ's are only 11 inches. This is only true for C4S's and C4's not so for C2 or C2S. The CH-R's offset is virtually the same as the Sport Techno's and are the same in all other dimensions.
