While the original Forgeline Concave Series wheels are designed with a flat reverse lip, the GA3C-SL Concave Stepped Lip wheel uses a standard stepped lip outer rim and unique full-length spokes that extend beyond the center’s rim register and reach over the step in the outer to deliver even more visual interest! This wheel was designed for today's modern sports cars and is a great choice for BMW 3-Series/5-Series, fifth-gen Camaros, Ferraris, S197 Mustangs, Nissan GT-Rs, and Porsche 996/997 Wide Bodies. (Other fitments are currently in development.)
The GA3C Concave combines the race-bred styling and I-beamed spoke technology from our incredibly successful GA1R monoblock wheel with three piece modular construction and a concave center profile to create a wheel with stunning good looks, aggressive character, and plenty of room for caliper clearance and extreme brake fitment.
Like all Forgeline Concave Series wheels, the GA3C locates the pad inboard of the outer rim to deliver depth and scale within the wheel center for a modern muscular look. Available in both deep concave profiles (for the most striking appearance) and shallow concave profiles (to create a staggered look or to accommodate narrow widths or higher-offset applications), these 3-piece wheels are assembled with American-made stainless-steel ARP fasteners in your choice of exposed through-bolt or hidden bolts with Heli-Coil inserts.
The GA3C is a custom made-to-order three-piece wheel that is produced from forged 6061-T6 aluminum centers with heat-treated rim-shells. And just like any Forgeline wheel, the GA3C is fully customizable in fitment and finish, including center lock applications.
