This bolt-on, deck-mounted Corvette Rear Wing Spoiler provides a more sturdy fit because the feet of the spoiler are finished to the exact dimensions of the wing moorings. These wings are produced using the World's finest high tech fiberglass process, known as Resin Transfer Molding (RTM). Fits 1984-1990 coupes and convertibles with slight modification. The RTM process does not use gel coat to help smooth the glass as it hardens. Instead, the fiberglass is molded over a foam core in die molds. Resulting in a Lighter yet Stronger Fiberglass!
