The wide body conversion kit will add some oomph and swagger to your C7 and installation, with the added benefit of allowing for larger wheels and tires, letting get the C7 power to the ground and improve acceleration times. Crucially, the OEM rockers do not need to be unglued from the car's aluminium rails - an expensive and dangerous procedure that would require that the doors are removed and potentially, through heating, distort the aluminium chassis. Fitting is estimated at 4 hours.


    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.
