This 10-gram rear chassis weight is a vital tuning component for 1/8 scale off-road buggies, specifically designed to enhance the performance of the Kyosho MP10 series. Crafted from high-density brass, its primary function is to strategically shift the vehicle's center of gravity towards the rear, optimizing handling characteristics for competitive racing. By adding this precise amount of mass to the rear chassis, drivers can experience improved rear wheel traction on loose or low-grip surfaces, enhanced stability through bumpy sections, and a more planted feel during acceleration and cornering, allowing for meticulous fine-tuning to suit various track conditions and driving preferences.
