Advanced Manufacturing Technology:
Forgestar's proprietary Rotary Forged Flow Forming process uses specialized equipment that spins the initial casting, applies heat to the outer portion, and uses steel rollers pressed against the rim area to shape it. The combination of heat, pressure, and spinning creates a rim with strength similar to a fully forged wheel. The pressure applied during flow forming changes the mechanical properties of the cast rim, so its strength and impact values become comparable to forged wheels, resulting in up to 15% less weight compared to standard cast wheels.
Performance Benefits:
- Lightweight construction ideal for street, drag racing, and track applications, with Forgestar's process delivering a wheel that's 15% lighter than most standard cast wheels
- Weight savings of approximately 6-10 pounds per wheel reduces unsprung weight, improving handling, braking, and acceleration
- Deep concave design provides bold styling and aggressive stance
- Compatible with tire pressure monitoring sensors (TPMS) and allows clearance for most high-performance brake caliper upgrades
- Load rated at 1520 pounds per wheel, considerably higher than typical cast wheels
