Zhigu's 2 piece wheels with a 4x100 bolt pattern are engineered for compact and sports cars, offering a balance of performance and style. The forged 6061-T6 aluminum center and spun-forged rim reduce rotational inertia by 20%, enhancing throttle response and braking efficiency. Available in widths from 7J to 10J and offsets from +20 to +50mm, they accommodate a wide range of tire sizes (195/55R16 to 255/35R18). A proprietary corrosion-resistant finish combines e-coat primer, powder coat, and clear coat for 750-hour salt spray resistance. These wheels are certified to JWL standards and compatible with OEM TPMS sensors.
