A selection of different size Shock Springs are available for the Hellfire.
The different springs have different stiffness and will make the suspension harder or softer depending on which spring is used. This offers a wide range of tuning of the suspension to the surface to improve the handling of the car on a variety of tracks.
The different sizes relate to the thickness of the wire used to make the springs. The thicker the wire or a lower number of coils mean that the spring is stiffer than a spring with thinner wire or more coils. Each spring features black plating with painted markings to help identify the different spring rates.
Each spring is rated in GF/MM and comes with a handy Spring Chart
