Zhigu's racing alloy wheels combine aluminum-magnesium alloy excellence with precision manufacturing, available in both low-pressure cast and forged variants. Cast wheels (A356-T6 alloy) offer cost-effective performance, ideal for amateur racing with 15% lighter weight than steel wheels and heat dissipation 20% more efficient than OEM castings. Forged alloy wheels (6061-T6) elevate performance further, delivering 30% higher tensile strength and 12% lower rotational inertia, critical for reducing lap times in professional racing. The multi-spoke design reduces air turbulence by 15%, while CNC-machined heat vents enhance brake cooling. These wheels meet FIA standards for load rating (up to 800kg per wheel) and undergo salt spray testing (500 hours) for corrosion resistance. Compatible with racing slicks and semi-slicks, they are available in staggered fitments for rear-wheel drive platforms.
