In the world of racing, weight is the enemy of acceleration. For that reason, anything that can be done to reduce the total weight of the vehicle by a reasonable amount usually is. Wheels are often the starting point when it comes to weight reduction and since every pound counts why not make them as light as possible? If you are in the market for extremely lightweight wheels, Weds Sports may have just the thing to satisfy you craving.
Weds is an aftermarket company based out of Japan and he recently developed a set of wheels made completely out of carbon fiber. The total weight of a single wheel comes out to about 6.1lbs. Which means a full set will only weight in at 24.4lbs.
To bring that into perspective, the average 15in steel wheel weights about 16lbs, adding up to 64lbs for a full set. A set of full carbon fiber wheels will save you 39.6lbs. I should also add that the wheels seen in the pictures are most likely larger than 15in. I would guess in the 17in or 18in range.
If you think a set of these are in your future, you should also take into consideration that they cost between $10,000 and $12,000. I guess the cost of winning can get pretty high.
