Xray X12 ‘Black’ C=1.1 Front Coil Spring
Extending its range of front coil springs for its X12 1:12 pan car, Xray has added this new Black C=1.1 option. For pan car front suspension with 4mm king pin axles, this option is the softest of the range and like the other 3 available springs is powder colour-coded for quick & easy identification. Developed through extensive testing and racing experience, the 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.
