Zhigu's aftermarket wheel rim provides a performance upgrade for OEM wheels, featuring a spun-forged aluminum barrel that replaces the stock rim. Available in sizes from 15-24 inches, these rims reduce unsprung mass by 15% compared to OEM cast rims, improving acceleration and handling. The manufacturing process includes CNC machining with 0.01mm precision and T6 heat treatment for enhanced strength. A proprietary "EdgeGuard" finish protects against curb rash and corrosion, with options for color-matched powder coat. These rims are compatible with most OEM wheel centers and come with a 5-year structural warranty.
