The all new ROTARY FORGED Series are manufactured
using a highly advanced production technique called rotary forging.
The rim of the wheels is forged at high pressure while the wheel is spun at high speed.
Our Rotary Forged process impacts the microstructure of aluminum by utilizing three hydraulic rollers to apply pressure to form the inner rim area. The rollers move down the barrel applying pressure to compress, stretch, and form the entire wheel barrel producing optimal weight savings while improving material strength. This process actually alters the grain of the aluminum to produce a wheel barrel that is significantly lighter with enhanced strength comparable to fully forged wheels.
ESR Rotary Forged Series helps reduce the weight up to 25% when compared to a standard cast wheel through this finer and more even aluminum structure
