Superstrong parts
Advanced forging processes now yield parts with directional strength and high impact resistance. A thin-walled ring takes shape on a ring mill. A spindle has been forged and is now being planished under the press to achieve a smooth surface, keeping stock allowance to a minimum. The open-die

Racing to tech transfer
the production version, in this case a 2006 Z06." Suspension attach points, for example, must stay within a 25-mm-diameter sphere compared with stock. And race cars can be only 100 mm wider than their stock counterparts. The C6-R is about 25 mm wider than a stock Z06, mostly to accommodate wide racing
