Abstract
Abstract The present invention relates to a vehicle wheel and more particularly to a light-weight wheel for high performance cars such as racing and sports cars. The wheel is constructed from wrought metal, which is better able to withstand stresses than the same metal which have been cast, by securing together, base to base, two generally dish-shaped members with a light-weight spacer means located between the bases.
