1984-1990 C4 ACI GTO Wide Body Kit without Rear Wing

Transform your C4’s stance and aerodynamic efficiency with this aggressive ACI GTO Wide Body Kit, specifically engineered for 1984–1990 Corvettes. This 6-piece gel-coated fiberglass body kit enhances airflow under and around the car, offering both styling and function in one performance-driven package. While the matching rear wing is sold separately, this version omits it by design to reduce drag and preserve high-speed balance—ideal for street and track use.

Features
• Fits 1984–1990 Corvette C4 models
• 6-piece body kit includes: 1-piece front spoiler, 2-piece side skirts, 2-piece door side panels, and 1-piece rear valance
• Rear wing intentionally omitted to reduce aerodynamic drag
• Improves airflow dynamics around and beneath the vehicle
• Made in the USA with gel-coated hand-laid fiberglass—ready to prep, prime, and paint

Dimensions and Weight
• Kit ships in multiple large-format fiberglass sections
• Total weight: approx. 42 lbs
• Shipping class: Oversize – truck freight required

Because Fit and Finish Matter
This wide body styling kit is designed for real-world builds—not factory duplication. Whether you’re prepping a race-ready street car or updating the attitude of your weekend cruiser, the ACI GTO kit delivers dramatic styling, performance airflow, and a race-inspired look that demands attention.

Gel Coat Finish & Handling of Imperfections
All fiberglass components are shipped in raw gel coat and may display surface variations, parting lines, or minor mold release marks. These are typical of aftermarket fiberglass and are not considered defects. The main thing we would also stress is that all fiberglass parts must be fitted to the car before any paint work is started. As you and I both know, no two Corvettes are the same.

Frequently Asked Questions Regarding Truck Freight

 

Question:  Why do my parts need to be shipped by truck?

Answer:  When Items that are too large to go by our normal carriers, they are shipped Truck Freight.

Question:  How is my freight price obtained?

Answer:  Freight pricing is based on multiple factors such as the shipment's freight class, density, route, and even how the items are packaged.  We contact a freight carrier and obtain shipping costs. We then add this to you order.

Question:  What do I or the freight company need to know about delivery?

Answer: You should know that your address (receiving location) needs to be adequate to accommodate a semi-truck.

 

Money Saving TIP: Typically we encourage you to provide a commercial address for delivery. Commercial locations/facilities can accommodate a large truck delivery and rates are often much less expensive.

Answer: After your order is placed and we contact the freight company for rates, we call you and advise the specific details of the shipment.

Answer: The carrier delivers to your destination and it is available to you at the “end of their trailer”.  It is your responsibility to be able to get it off the truck,

Question: What about heavy items like motors, transmissions and complete front ends?

Answer: If you are going to need a truck with a lift gate, we need to know that in advance of getting a quote for freight costs. If your items are to be delivered to a location with a freight dock, we also need to know that information.
