Serpent have introduced new Cobra buggy rear springs. The new springs have less coils, less wire than before while retaining the same length. The new configuration means a more progressive character to increase steering, especially on corner entry, and also feels more stable on landing. Each spring is ground flat, individually checked for straightness, paired in sets of 2 and are color coded as before. The springs will fit many other brands of cars with 16mm big bore shocks.
