Spoiler Blade 70 Deg 5in IMCA Stok Car

The Spoiler Blade 70 Deg 5in IMCA Stock Car from FIVESTAR is purpose-built for competitive short-track racing where aerodynamic efficiency directly impacts lap times and fuel economy. Designed specifically for IMCA (International Motor Contest Association) stock car regulations, this rear wing element addresses the fundamental physics of vehicle dynamics—generating controlled downforce at the rear axle to improve traction during acceleration and cornering while maintaining the stock-car aesthetic mandated by rulebooks. Racers and suspension-tuning enthusiasts rely on this blade to balance high-speed stability with low-speed maneuverability on oval tracks.

The 70-degree blade angle represents a critical design compromise in racing aerodynamics: steep enough to generate meaningful rear downforce on straightaways and high-speed turns, yet shallow enough to minimize drag and comply with IMCA technical specifications. At 5 inches in height and weighing just 2.037 pounds, this blade integrates seamlessly into compact vehicle platforms without excessive weight penalty—a vital consideration in spec racing where every tenth of a pound affects acceleration and braking performance. The lightweight construction and narrow 0.75-inch profile reduce wind resistance while the 28-inch length spans most stock-car roof or deck mounting points, ensuring consistent airflow attachment across the entire rear surface.

This spoiler blade is engineered for drivers competing in IMCA-sanctioned classes where aftermarket aerodynamic upgrades are permitted and where reliable downforce translates directly to competitive advantage. Installers should verify local tech inspections and rule interpretations, as IMCA regulations occasionally vary by region and division; the blade's dimensions (28 x 6 x 0.75 inches) fall within standard allowances for most oval-track formats. Whether you're tuning a weekly short-track racer, building a weekend warrior, or developing a car for endurance competition, this FIVESTAR component delivers measurable aerodynamic function within regulatory boundaries.
