Zhigu's forged concave wheels feature deep concave profiles (offsets from -20 to -80mm) achieved through multi-piece forging or specialized monoblock designs. 2-piece models have removable outer rims for width adjustment (up to 12J), while 3-piece designs allow independent customization of inner and outer rims. Made from 6061-T6 forged aluminum, they undergo additional impact testing on concave areas (1.8x standard load). Finishes include diamond cut with a 20-micron clear coat, liquid metal, and custom colors. Ideal for luxury coupes (Mercedes-AMG GT), show cars, and wide-body modified vehicles.
