What is FORMULA 43? - The technology

Formula 43 modular wheel center sections use a Rotary Forged process that results in a superior, tighter and 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 5 degree angle. The material then flows in 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.
