GM Wide Body Conversion Kit for the Stingray C7 Convertible 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 serious swagger to your C7 Stingray. By extending the rear width, new width tires and wheels can be added to truly the your C7's power to the test!

The main benefit of this package is that the OEM rockers do not need to be unglued from the car's aluminium rails - an expensive and dangerous procedure that would require removing the doors, and potentially causing distortion due to aluminium heating. The combination of ACS Composite and GM parts enables a true bolt on widebody that can be easily installed in a few hours.
