Zhigu's lightweight alloy wheels leverage forging technology to achieve industry-leading weight reductions, with 18x8J rims weighing as low as 7.2kg (25% lighter than equivalent cast wheels). The weight-saving strategies include: optimized spoke geometry (hollow spoke design), thin-wall forging (wall thicknesses as low as 2.5mm), and flow forming for material distribution. These wheels enhance vehicle performance by: improving acceleration (0.3-0.5s faster 0-100km/h), reducing braking distance (1-2m shorter at 100km/h), and enhancing cornering grip (5-8% better lateral acceleration). The lightweight design also improves fuel efficiency by 2-3% and reduces suspension wear. All lightweight wheels meet JWL/VIA standards, with additional high-speed testing at 300km/h for stability.
