Couldn't load pickup availability
The Forgeline GA3C-SL Stepped Lip is derived from our GA3C Concave wheel—designed 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.
With the same race-bred styling and a standard stepped lip design, the GA3C-SL Stepped Lip features unique full-length spokes that extend beyond the rim register and over the step in the outer rim.
The GA3C-SL Stepped Lip is engineered with an aggressive concave center profile, I-beamed spoke technology, and generous caliper clearance for extreme brake fitment.
The GA3C-SL Stepped Lip is available in deep and shallow concave profiles.
The GA3C-SL Stepped Lip is a precision-machined 3-piece wheel, made using our traditional forging method.
