I never realized they were composite. Would have been cool if they were asymmetrical as well.

Looking around, I found this quote, “They aren’t that light. I’ve got a couple of them (both cracked). I’ll weigh them if I ever think about it. For drag wheels there are much lighter options, for autocross/road racing I’ve seen first hand a CSX pull the lugnuts right through the wheel in a turn – really tears up alot of parts on a rare car when the wheel comes off at speed in a corner.”

Ain’t no JWL rating on them.
