Attention well-heeled supercar drivers looking to shed a few ugly pounds. The design prop-heads at the UK's Project Kahn have come up with a wheel that weighs as much as a load of laundry. It's the RS-X, which sports a carbon fiber rim around a magnesium core. The result is a major reduction in radial inertia, resulting in improved acceleration, and unsprung weight, which affects handling responses. Each set is custom made for each vehicle, and at a price of around
$6000 $4000 per wheel, you might want to hit AutoZone for a set of curb feelers.
