ACS Composite Wide Body Conversion Kit for the Chevrolet Stingray C7 Convertible 2014-19 

ACS pride themselves in offering premium, quality engineered parts that are imbued with the attention to detail that reflects their passion.  ACS is constantly working on new innovative solutions to provide the greatest options for Corvette enthusiasts everywhere. The latest creation is a family of panels to widen and enhance the already great C7 Stingray.  

Designed from the ground up utilizing computer-aided engineering, GM's OEM zero spec data and manufactured in RTM composite, ACS parts dispel the myth of poor-fitting aftermarket parts. Panels are sold fully prepped and primed, and ready for trial fitting. The final result is a widen C7 Stingray rear delivering an aggressive visual appeal and extra clearance for massive 12” wheels fitting P335/25ZR20’s.

The wide body conversion extends the rear quarter kit by almost 2 inches per side to add some oomph and swagger to any Stingray, for both coupe and convertible. Larger wheels and tires means more C7 power can get put to the ground and stick!

The added benefit of the ACS widebody is that the OEM rockers do not need to be unglued from the car's aluminium rails. This is an extremely expensive and dangerous procedure that would require the door removal, which is likely to lead to the distortion of the aluminium chassis. Every detail has been addressed: From wheel liners to fasteners, and even new rear rear splash guards that comes to finalize the new widen rear!

A scooped version, like the Z06 is available with functional brake cooling ductwork, or a refreshing conservative smooth version for the stealthy cleaner appeal. Both version are bolted and quickly installed for a perfect fit and finish.

The scooped Convertible version can be found here

  • The addition of 40mm width on each side. 20x12" wheels and P335-25-20 tires can now be fitted.
  • Side rocker extensions (driver & passenger).
  • Rear quarter panel (driver & passenger).
  • Rear Fascia extension (driver & passenger).
  • Rear Wheel liners (driver & passenger).
  • Rear splash guards (driver & passenger).
  • All necessary hardware.
How difficult of an install is the widebody? Can I do it myself, or should I seek a professional? Do any extra modifications need to be done to the car to get this to fit?

The widebody is more of a lengthy install than it is a difficult one. Professional help is always great, and takes the burden off the customer! But, everything is included to install it yourself. Detailed instructions guide you through the entire install. No extra modifications are needed to get the widebody to fit (i.e no cutting extra panels, trimming, sanding down body lines etc).


Does the widebody come prepainted?

No. It comes in a primer finish. This is a to-be-painted surface that will require a final sanding prior to paint. We offer paint matching with select C7 colors. It is an additional $1,750.00 to paint all pieces. Please email order@acscomposite.com for more details


Does this wide body widen the front wheels as well?

No. This widebody is for the rear portion of the car only.


Can I keep the rear wheels and tires that I have now?

Technically, yes you can retain your tire and wheels; however, it will look odd! Your rear fascia will be wider than your wheel, and therefore you will not be able to see your tire and wheels. It is highly recommended to upgrade to a 20x12" wheel similar to the Z06. ACS offers a selection of wheels that can be viewed on our configurator. Please contact us directly at order@acscomposite.com for pricing.
