Produced from a single piece of aluminum alloy, these wheels are forged under high temperature and pressure to ensure exceptional strength and rigidity. Using techniques derived from the aircraft industry, the use of one-piece forgings eliminates the possibility of porosity and allows for the most efficient use of material for low weight and maximum visual appeal. These exceptional wheels are produced using a highly labor intensive polishing process which achieves a mirror finish from the base metal. The process incorporates both hand polishing and ceramic ball polishing, which is derived from techniques used to produce components for high-performance Formula 1 engines. The meticulous craftsmanship required for the production of these polished wheels offers customers a compelling alternative to standard chrome wheels This rim style was launched on the Rapide S.
