Advantages of lightweight flow formed wheelsApril 17, 2009
Forgestar F05 19x10 offset +40 22.6 lbs or in metric 10.25 kg Forgestar Performance Wheels is the leader in lightweight custom flow formed wheels. Forgestar's Flow Forming technology allows us to manufacture wheels that are both light and strong. Flow Forming is a production procedure that turns the wheel (or rim section) over a special mandrel and three hydraulic rollers using tremendous pressure. The pressure and turning then force the rim area to form against the mandrel, creating the shape and width of the rim. During Flow Forming, the rim actually "flows" down to create the full rim width. During Flow Forming, pressure applied to the cast rim actually changes its mechanical properties, so its strength and impact values become similar to those of a forged rim. That translates to up to 15% less weight when compared to a standard cast wheel. Our technological breakthroughs in heat treating allow us to increase dent resistance without having to make the wheel heavier. While many people choose alloy wheels for their beauty, there are equally important performance benefits to be derived including... Reduced Unsprung Weight This is one of the most critical factors affecting a vehicle's road holding ability. Unsprung weight is that portion of a vehicle that is not supported by the suspension (i.e. wheels, tires and brakes) and therefore most susceptible to road shock and cornering forces. By reducing unsprung weight, alloy wheels provide more precise steering input and improved "turning in" characteristics. Improved Acceleration and Braking By reducing the weight of the vehicle's rotational mass, alloy wheels provide more responsive acceleration and braking. Added Rigidity The added strength of a quality alloy wheel can significantly reduce wheel/tire deflection in cornering. This is particularly critical with an automobile equipped with high performance tires where lateral forces may approach 1.0g.
