The Forgeline GA1R is a fully-forged one-piece monoblock wheel that utilizes much of the technology and design of our very successful GA3R racing wheel, including our "I-beamed" spoke technology. The concave design of the GA1R not only looks great, but allows plenty of room for caliper clearance and extreme brake fitment, while the one-piece monoblock forging and I-beamed spoke design yield a wheel that is extremely stiff with fatigue strength equal to our proven GA3R. And yet despite the strength and stiffness, for most applications and sizes, it also delivers a high-performance weight reduction - making it perfect for motorsports and racing applications or the discerning street enthusiast who demands the ultimate in performance capability!
