RB1

The Forgeline RB1 is a fully-forged one-piece monoblock wheel that utilizes manufacturing technology similar to our very successful GA1R wheel. The RB1 features a concave 10-spoke design with a subtle directional twist on each spoke, so each set includes unique left and right versions. The RB1 also utilizes Forgeline’s I-beam technology along each spoke and along the front lip between spokes to reduce mass and enhance strength & rigidity. And our one-piece monoblock forging and computer-simulated FEA design process yield a wheel that is lightweight, extremely stiff, and has excellent fatigue strength. 

The RB1 is machined from a single forging of 6061-T6 aluminum. It is currently available in 18, 19, 20, and 21-inch diameters with a range of widths and offsets. (Please Note: Depending on size, the RB1 may be available in deep, medium, or shallow concave profiles. See sizing chart for details.) And just like any Forgeline wheel, the RB1 is available with fully customizable finish options.

The RB1 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).
