Show original supplier description
This cap is engraved with “Forgeline Motorsport” to protect the hub spindle from the elements. Utilizing I-beamed spoke technology, the GA1R Open Lug Cap is engineered for significant weight reduction, with material machined from the center for an aggressive concave look and improved access to lug nuts. Depending on size and offset, it can save up to an additional pound per wheel compared to the standard GA1R. This wheel is built for hardcore track use, boasting a load rating of over 2100 lbs for street tires and generous caliper clearance for extreme brake systems, employing manufacturing technology similar to Forgeline's successful GA3R racing wheels. Constructed from a single forging of 6061-T6 aluminum, this one-piece monoblock wheel is available in various concave profiles—deep, medium, or shallow—depending on the chosen size and offset. Forgeline wheels are custom-made-to-order in the USA, allowing for precise matching to vehicle specifications and intended applications, including custom sizes, lug patterns, and backspacing/offsets. The wheels are finished by hand with a durable powder coat in virtually any color.
