Xray X12 4mm Pin Front Coil Springs

New from Xray for its X12 1:12 chassis and other brands of cars with 4mm king pin axles are these soft and ultra soft front coil springs.  Adding 0.9 Soft ‘Silver’ and 0.7 Ultra Soft ‘Gold’ spring options, the new additions are used for more forgiving handling and improve mid cornering.  Developed through extensive testing and racing experience. Stiffness is controlled by the thickness of the wire and by the number of coils; softer springs have a lower “C” value, while stiffer springs have a higher “C” value.
