The Serpent SER401802 is an Arrowspace magnesium upgrade aimed at drivers who want a lighter, stiffer base for their Project 4X PRO EP machine. Its construction focuses on trimming mass while keeping structural integrity for race work.
As one of the lightest engineering metals, magnesium lowers the car's mass without sacrificing rigidity. That translates to snappier acceleration and a more reactive feel under steering inputs, useful when pushing in traffic or tight sections.
Designed specifically for Project 4X Series cars, the chassis installs using the factory mounting points for minimal fuss. It is ideal for drivers tuning balance for mixed indoor and outdoor club tracks.
A sensible upgrade for racers wanting a lighter baseline to develop handling and setup choices.
