GM Wide Body Conversion Kit for the Stingray C7 Coupe 2014+

A complete bolt on Rear Wide Body kit using OEM Panels and an ACS lower rocker integration panel.

The wide body conversion kit will add swagger to your C7 by enabling a wider wheel and tire in the car--Giving it that true sports car look! A wider tire and rear helps to keep the C7 power to the ground and improve acceleration times.

This is the safest and easiest way to get the Z06 widebody on a Stingray. Using this kit, the OEM rockers do not need to be unglued from the car's aluminum rails - an expensive and dangerous procedure that would require that the doors to be removed and potentially, through heating, distort the aluminum chassis. Utilizing mostly GM parts and the ACS lower rocker integrator panel, the kit is a true bolt on making it ideal for any shop or home modder to widen the Stingray's rear. Fitting is estimated at 4 hours. Panels do need to be color matched.

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

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.
