This is an optional Kyosho Soft Short Front Spring Set, and is intended for use with the Kyosho Mini-Z MR-03. This package includes five sets of springs, that are .5mm shorter and softer than the springs included with the MZW410 spring set. This spring set allows optimum settings to be achieved on cars with aluminum front upper arms (MZW415) and the inner tube shock set (MZW416). The magenta springs are soft, the deep purple springs are medium/soft, the light green springs are medium, the dark orange springs are medium/hard and the lemon yellow springs are hard.
