While the original Forgeline Concave Series wheels are designed with a flat reverse lip, the RB3C-SL Concave Stepped Lip wheel uses a standard stepped lip rim to deliver even more visual interest and weight savings! 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 Forgeline RB3C-SL forged concave stepped lip wheel combines a deep-dish concave profile, a directional 10-spoke pattern (with full-length spokes that extend beyond the center’s rim register), and a weight-saving stepped lip outer rim. And thanks to Forgeline’s unique performance-inspired concave design philosophy and beveled spokes, the RB3C-SL delivers both beauty and performance.

The RB3C-SL is a stepped lip variation of the Forgeline RB3C forged concave wheel that was developed in conjunction with the famous Ringbrothers and installed on their award-winning Producer Mustang at SEMA 2011. It features a unique concave design with subtle directional spokes. This wheel includes separate left and right versions and is available in both a deep concave profile (for the most striking appearance) and a shallow concave profile (to create a staggered look or to accommodate higher-offset applications). This is a 3-piece wheel assembled with hidden stainless-steel ARP fasteners and Heli-Coil inserts - and is also available with the through-bolt option.

The RB3C-SL is a custom made-to-order three-piece wheel that is produced from forged 6061-T6 aluminum with heat-treated rim-shells. And just like any Forgeline wheel, the RB3C-SL is fully customizable in fitment and finish, including center lock applications.
