Asphalt modified race cars are designed to optimize performance on modified asphalt surfaces. These vehicles utilize specialized tires and suspension systems that enhance grip and stability on high-friction tracks. The asphalt or bitumen modification processes involve adding polymers or rubber to the asphalt mix, improving its elasticity and durability. This results in a smoother racing surface that reduces tire wear and enhances traction, ultimately allowing race cars to achieve higher speeds and better handling during competitions.
