^^^ ouch. Yeah, that's from a GT2 and kerbs. He was hitting he kerbs hard because the CF can take it. Guess the center was a different story. I'm told he had a crack in one of the wheels but ran it anyway, and still used the kerbs. Scary, but he got away with it. Yes, the new Dymags come with a compound they call Magnalium. All the strength of aluminum alloy with the weight saving of Magnesium. I'm told under 14 lbs front and under 18 lbs rear in GT sizing.
I doubt the HRE's will be much heavier, but they will have the solid advantage of far more rim options!!!
As an example of light, when I was picking mine, the REARS were super easy to pick up with ONE hand, like a bicycle wheel!!! They were significantly lighter than the 10 spoke forged BBS which previously felt unbelievably light to me. :thumbsup
