One of our local customer's here in Detroit Al Sharp and his 67 Camaro with Formula 43 RAD5.
Formula 43 modular wheel center sections use a Rotary Forged process that results in a superior tighter, circular grain structure. The rotary forged center section begins life as a cylinder of billet. The billet is then heated and placed into a die in the rotary forging machine. The die spins the billet at 300RPM while the billet is pressed from above at a 5 degree angle. The material then flows in a circular pattern into the die. The new forging is then heat treated, quenched and aged to T-6061 standards. The end result is a rotary forged center section that has stiffer spoke dimensions, lighter weight and a quicker moment of inertia.
