Couldn't load pickup availability
The Forgeline RB3C-SL Stepped Lip is derived from our RB3C Concave wheel—developed in collaboration with the famous Ring Brothers.
Featuring the same 10-spoke design with subtle directional twist on each spoke, the RB3C-SL has separate left and right wheels to ensure consistency in directional rotation.
Engineered with a standard stepped lip outer and generous caliper clearance, the RB3C-SL is an ideal choice for modern sports cars including, BMW 3-Series, BMW 5-Series, fifth-gen Camaros, Ferraris, S197 Mustangs, Nissan GT-Rs, and Porsche 996/997 Wide Bodies.
The RB3C-SL Stepped Lip is available in deep and shallow concave profiles.
The RB3C-SL Stepped Lip is a precision-machined 3-piece wheel, made using our traditional forging method and assembled with hidden ARP hardware.
