ZR1-style rocker extensions for the wide body C6 Corvette, molded in ABS plastic and sold as a left and right pair. Pick unpainted matte black, painted gloss black, or a hydro-dipped carbon weave — all three bolt to the factory mounting points.
ABS Plastic · ZR1 Style · Three Finishes

This is the ZR1 rocker treatment for wide body C6 Corvettes — a matched left and right pair that runs the length of the rocker and adds a ground-effect edge under the door. The extensions are molded in ABS plastic and shaped to follow the factory body contour, so the extension reads as part of the car instead of a strip bolted along the bottom.
Three finishes cover the usual build directions: unpainted matte black if you plan to spray them your own color code, painted gloss black if you want them ready to mount, and a hydro-dipped carbon weave if the rest of the car already wears carbon. All three share the same mounting — pre-drilled holes (where applicable) that line up with the factory mounting points, fasteners and an installation guide in the kit, and no cutting or drilling. Professional installation is recommended for the best alignment and finish.
