Backing Disc 4pk Spoiler Brace

The Backing Disc 4pk Spoiler Brace from LONGACRE is designed for serious racers and high-performance vehicle builders who require reliable aerodynamic mounting systems. This four-pack of backing discs serves as the essential foundation for spoiler and wing assemblies, ensuring that your downforce-generating components remain securely fastened under extreme cornering loads and track conditions.

Manufactured from precision-machined steel, these backing discs are engineered to distribute clamping load uniformly across mounting surfaces, which helps to eliminate stress concentrations that could weaken composite or fiberglass spoiler structures. The dimensions of 5.55 x 7.1 inches with a thickness of 0.5 inches provide the necessary support to maintain alignment under high-speed aerodynamic stress and thermal cycling.

Competition drivers, fabricators, and motorsports shops benefit from the reliability of LONGACRE backing discs, which help to prevent wobble and creep in wing mounts that can negatively affect lap times and vehicle stability. The included four-pack quantity ensures you have spares or can outfit multiple mounting points on your vehicle's aero package, making these discs compatible with most aftermarket spoiler bracing patterns.
