ZR1-style rocker extensions for the wide-body C6 Corvette, sold as a left/right pair in four finishes — from unpainted matte black ABS to real carbon fiber. Pre-drilled mounting holes line up with the factory mounting points, so the pair bolts on without cutting or drilling.
ZR1 Style · Bolt-On Pair · Four Finish Options

A wide-body C6 carries a lot of visual real estate between the front and rear arches, and the factory rocker leaves that span flat. These ZR1-style extensions mount along the rocker to pull the side line lower and tie the flares together, so the car reads longer and closer to the ground in profile. The ground-effect shape also manages airflow down the sides of the car, which cuts lift and steadies things at speed.
Four finishes cover the usual builds. Plastic Black arrives unpainted matte for anyone planning body-shop color, Glossy Black comes finished out of the box, Hydro-Dipped Carbon puts the weave look on an ABS shell, and SS-028-BKCF is real carbon fiber under a UV-resistant clear coat. Every finish runs the same shape and the same pre-drilled mounting points, and each piece is fitment-tested for precise alignment.
Unpainted matte black, painted glossy black, hydro-dipped carbon, or real carbon fiber.
The SS-028-BKCF set is real carbon fiber with a UV-resistant clear coat over the weave.
Manages airflow along the sides of the car, reducing lift and improving high-speed stability.
Contoured to the C6 rocker so the extensions read as part of the car, not bolted on.
Pre-drilled holes align with factory mounting points — no cutting, drilling, or trimming.
All necessary mounting fasteners plus an installation guide come in the kit.
