Weds Sports, a Japanese wheel-maker, has created a full carbon fiber wheel -- rims, spokes, hub, everything -- that weighs 2.76 kg. Coming out to about 6.1 pounds, that's about half the weight of the Dymag carbon fiber wheel with a magnesium rim that you'll find on a Callaway Corvette, and just over a pound more than Dymag's all-carbon race-specific front wheel for a motorcycle.
According to a rough translation of Weds' literature, they use a dry carbon fiber process that makes the wheels strong enough for... well, we're not really sure. While the rims look absolutely ace, we can't find any other company that makes an entire wheel out of carbon fiber, and Weds apparently hasn't yet put them in production, which leads us to think that these babies were meant only for the scales at the Tokyo Auto Salon. But if you have $12,000 for a set of four, and you live in an area with no potholes and no curbs, these could be the rims for you.
