Rotary Forged, what is that?
Rotary Forge is an advanced manufacturing process used to produce stronger and lighter weight cast wheels.​
How does it work?
Wheel manufacturers cast the wheel with a narrow barrel. (as little as 4" wide). They then spin the wheel at a high speed, and at a high pressure, forge the barrel out to the desired width and shape.
What's the benefit?
This process alters the molecular structure and enhances the strength of the wheel. It also helps keep the wheels weight down when compared to traditional cast wheels. Most importantly, the weight savings is in the outer rim of the wheel which dramatically reduces rotational mass and enhances vehicle performance.​

TSW has been using Rotary Forge technology to manufacture the Nurburgring and they are now using it to manufacture their New Interlagos as well. Those of you looking for a wheel upgrade that will help enhance the look and performance of your vehicle take a good look at these two options.
