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!
The GA1R is designed for racing. It is engineered with a 2100 lb. street-tire load rating (per wheel) to ensure strength and integrity, even when subjected to the massive loads encountered on the stickiest race tires.
The GA1R is produced using our traditional forging method from 6061-T6 aluminum. It is currently available in 18, 19, 20, and 21-inch sizes with a range of widths and offsets. (Please Note: Depending on size, the GA1R may be available in deep, medium, or shallow concave profiles. See sizing chart for details.) And just like any Forgeline wheel, the GA1R is available with fully customizable finish options.
The GA1R is also available for limited applications in Deep Cap (DC) and Extra Deep Cap (EDC) profiles. These Deep Cap profiles employ unique in-house lathe turnings that allow us to position the center cap deep within the center of the wheel and create an exaggerated extra-aggressive concave look. This option is an excellent choice for select vehicles including the BMW M3, Nissan GT-R, ZL1 Camaro, C6 Z06 Corvette (rear only), and certain Porsche models (rear only).
