Show original supplier description
The ACS Composite C7 Stingray Coupe Rear Widebody Conversion Kit is engineered to significantly enhance the aesthetic and functional capabilities of your C7 Corvette Stingray Coupe (2014-2019). This true bolt-on kit is designed with precision, utilizing GM's OEM zero spec data to ensure a perfect integration with your vehicle's existing structure. It provides an additional 40 mm of width on each side, specifically enabling the fitment of larger wheel and tire combinations like 20x12 wheels with 335-25-20 tires, which can improve traction and acceleration. The RTM (Resin Transfer Molding) process uses high pressure and heat to create solid, smooth fiberglass panels that are stronger than traditional hand-layup methods. The kit includes essential components such as driver and passenger side quarter panels, rocker extensions, rear quarter upper scoops (Five1 model), a rear fascia extension, and splash guards, all designed to work harmoniously for a cohesive widebody appearance. A key advantage of this ACS Composite kit is its user-friendly installation. Unlike other wide body kits, it does not require the problematic and costly process of ungluing OEM rockers from the car's aluminum rails. The estimated installation time is approximately 4 hours, making it a relatively hassle-free upgrade. The kit comes with a primer surface finish (RPO: PRM), ready for custom painting to match your Corvette's aesthetic. Tools required for installation include a 7mm socket, M6 socket, and a pry tool.
