Zhigu's custom racing wheels are precision-engineered for competitive edge, featuring 6061-T6 forged aluminum construction with FEA-optimized spoke geometries that reduce unsprung mass by 22% compared to OEM alternatives. Each wheel undergoes 3D scanning for custom offsets (-20 to +60mm), enabling perfect alignment with wide-body kits. The high-pressure forging process creates a molecular structure capable of withstanding 1200 Nm of torque, ideal for turbocharged engines. Aerodynamic spoke designs reduce drag by 18% and improve brake cooling by 25%, as validated by CFD simulations. Finishes include aerospace-grade anodizing in 12 standard colors or custom Pantone matching, with laser-etched logos and serial numbers. Tested to JWL+R and TUV standards, these wheels are compatible with racing slicks up to 345mm width and come with a 5-year structural warranty.
