Zhigu's 2 piece wheels provide modular customization and performance, featuring a forged 6061-T6 aluminum center and a spun-forged aluminum rim. This design allows for precise adjustments to width (7-14J), offset (-30 to +50mm), and concave depth (up to 3.5 inches). The two components are secured by 12.9-grade steel or titanium fasteners, ensuring a strong and reliable connection. Each wheel undergoes CNC machining with 0.02mm precision and T651 heat treatment for uniform hardness. A proprietary finishing process includes e-coat primer, powder coat, and clear coat for 750-hour salt spray resistance. Certified to JWL and VIA standards, these wheels are suitable for a wide range of vehicles, from compacts to full-size trucks.
