One of the easiest ways to elevate both the look and functionality of your C8 Corvette Stingray is by upgrading the factory rocker panels. Our friends at ACS Composite offer three distinct rocker designs for the 2020+ Stingray, each inspired by motorsport styling and engineered for real‑world protection.
Whether you prefer a clean, understated profile, a bold OEM‑plus look, or a dramatic, sculpted design that turns heads, ACS has a side rocker option tailored to your taste. Their 1VM, 5VM, and 7VM Rockers all share ACS Composite’s signature PC Composite construction, Carbon Flash Metallic finish, and no‑drill installation, but each brings its own personality to the C8 Stingray platform.
1VM Side Rockers
ACS Composite’s 1VM Side Rockers take their cues straight from Corvette Racing’s C8.R “barge board,” adopting that same straight‑back, step‑out profile that runs cleanly from the front wheel opening to the rear. The result is a purpose‑built rocker extension that looks factory‑right on the Stingray without shouting for attention. If you want a more conservative, wing‑free aero package for your C8, pairing the 1VM Rockers with the matching 1VM Front Splitter is a smart, cohesive way to go.
ACS manufactures the 1VM C8 Rockers using their latest PC Composite material, which has proven to be stronger and more durable than fiberglass, carbon, or ABS alternatives. The rockers shrug off heat and rock impacts, and the extended undertray shields the vulnerable painted sections along the underside of the car. Finished in Carbon Flash Metallic, they blend seamlessly with the rest of the C8’s exterior trim, and they’re fully compatible with ACS Composite’s C8 Rock Guards for even more protection from road debris.
Installation is straightforward thanks to a supplied rocker bracket and aluminum black split rivets. Unlike the dealer‑installed 5VM rockers, ACS’s 1VM design requires no drilling into the body, which means the upgrade is completely reversible with no visible holes left behind. ACS also provides an installation video that walks through the process, highlights the differences between their 1VM Rockers and GM’s 5VM design, and shows how to remove the OEM Z51 rocker extension before fitting the new pieces.
Designed for all 2020+ Corvette Stingray Coupes and Convertibles, the ACS Composite 1VM Rockers fit both Z51 and non‑Z51 models. Pricing is $1,699 for the pair, and shipping is free.
5VM Side Rockers
If you’re one of the enthusiasts who loves the bold, motorsport‑inspired stance of the OEM 5VM side skirts with those unmistakable winglets ahead of the rear wheels, ACS Composite has taken that look and elevated it with their ACS 5VM Carbon Flash Rockers for the C8 Corvette Stingray. As with the 1VM design, ACS incorporates an extended undertray that shields the rolled, painted rocker surface underneath the Stingray, and they’ve engineered a custom rocker bracket that eliminates the need for the dealer‑required side‑hole drilling found on GM’s factory 5VM install.
ACS already offers their own 5VM‑style Front Splitter, and these 5VM Rocker Panels in Carbon Flash Metallic complete that aggressive aero package. Built from ACS’s ultra‑durable PC Composite material, the molded black rockers are heat‑resistant, impact‑resistant, and because the substrate itself is black, any scrapes or chips are far less noticeable than on fiberglass or carbon‑skinned parts.
Finished in Carbon Flash Black (CFZ), the ACS 5VM Rockers match the C8’s factory exterior accents perfectly, from the front grille and side intake boomerang to the rear diffuser and everything in between. It’s a cohesive, OEM‑plus look that blends seamlessly with the Stingray’s design language.
ACS Composite’s 5VM Carbon Flash Black C8 Rockers will fit on all C8 2020+ Stingrays. Pricing is set at $1,948 for the pair, and as always, shipping is free.
7VM Side Rockers
If you’re looking to move beyond the ordinary and give your C8 Stingray a truly distinctive edge, ACS Composite’s 7VM Side Rockers deliver exactly that. These full‑length side rockers add both protection and presence, showcasing a bold “inverted‑seven” profile capped with a sculpted shark‑fin detail. An extended undertray shields the painted rocker surface underneath the car, and the design integrates seamlessly with ACS’s best‑selling Rock Guards for even more debris protection. It’s an instant upgrade in both style and function for any Stingray owner.
The 7VM Rockers are injection‑molded from ACS’s proprietary PC Composite material, which is exceptionally durable and far more forgiving than carbon fiber when it comes to chips or scrapes. Because the substrate is black, any marks are far less noticeable, and the Carbon Flash Metallic topcoat ensures a perfect match with the C8’s factory accent pieces—from the front grille to the rear diffuser and everything in between.
Installation follows the same proven process as ACS’s other C8 rocker options. The 7VMs use the three OEM mounting points along with a supplied rocker bracket and aluminum split rivets, and no drilling into the body is required. That means the upgrade is fully reversible, with no permanent modifications left behind.
ACS Composite offers the C8 Stingray 7VM Rockers for $1,848 with free shipping. An installation video is available showcasing the 7VM Rockers alongside the matching 7VM Front Splitter, complete with an installation walkthrough from Joseph.
For the ultimate cohesive look, pair the 7VM Rockers with the 7VM Front Splitter, which mirrors the same inverted‑seven styling and features larger, more dramatic winglets. The 7VM Front Splitter is priced at $879 and also ships free.

RIP Accelerate Yellow Metallic. Just the comparison of AYM to the Competition Yellow on the production line in the assembly plant tours article…is a grim, painful reminder of what was lost.
We gave up the most vibrant, pure yellow ever to grace a Corvette–and replaced it with baby-poop-mustard-yellow. Because apparently C8 colors have to be stodgy. And it isn’t just yellow. Amplify Orange became Seabring. Rapid blue is gone entirely. Hysteria is neither Violet nor Eggplant. Roswell is neither Lime nor British Racing Green (after the swing-and-a-miss that was Cacti).
Even Admiral Blue looks better on the INTERIOR of a Super Duty than as a Corvette paint color. There, I said it.
I couldn’t agree more
