Zhigu's forged wheel rim represents the pinnacle of strength and lightweight design, forged from 6061-T6 aluminum using a 15,000-ton press. This process creates a grain structure 50% denser than cast rims, resulting in a 30% strength increase and 25% weight reduction. Available in widths from 7J to 16J, these rims support extreme offsets (-40 to +60mm) and concave depths (up to 4.5 inches). A proprietary heat treatment process increases fatigue life by 40%, critical for high-stress applications. Each rim is X-ray inspected for internal defects and certified to FIA standards for motorsport use.
