Serpent S400 Aluminium CVD Shafts
New for the Serpent S400 are these anodized aluminium CVD drive shafts. Super lightweight, they are 3 grams lighter than the steel versions, giving a saving of 12 grams when used throughout the car. This weight gain means reduced rotating mass, which translates into faster acceleration and top speeds. Sold in a set of 2, they are suitable for the front and rear of the car, but due to the current power being delivered by modern electronic equipment it is advised to use them only the rear, as when used on the front they may wear quicker than the standard steel versions.
