[Shotimes] Gas Mileage and British Sports Cars

[David Rosicke]

The KDW's dropped my mileage at least 2 points over the CompT/A VR4's.  The 15" rim/tire combination should be about 10 lbs lighter/wheel - the VR rated tires are heavy and the 16" rims are a couple of lbs heavier than the 15" basketweaves.  Less rotational mass = better power to the ground and better mileage. Enkei even advertised this with their rims when installed on SUV's.

Your expectations seem a bit high to me for a tire and wheel change. What
your basis for such a large improvement?
