Mini Inferno ST Precision Spring Kit 12pc MIF-001A by 3Racing  [MIF-001A]

Technical overview for MIF-001A springs

The MIF-001A spring kit provides a direct-fit 12 piece front and rear assortment for Kyosho Mini Inferno ST shock assemblies, offering discrete soft, medium and hard rates. Designed for 1/18 scale applications, the kit lets tuners alter static and dynamic spring rates without replacing shock bodies or pistons.

Service procedures follow standard shock maintenance: remove caps, extract original springs and refit the selected rates while preserving spring orientation and preload settings. No specialised machining or modification is required; standard shock tools suffice and the springs are intended for coil-over style shocks on the Mini Inferno chassis.

From a setup perspective, use softer springs to improve tyre compliance and mechanical grip on uneven or low traction surfaces, and employ stiffer springs to control roll and speed up transient weight transfer on sealed or smooth layouts. Evaluate front to rear combinations methodically, record lap-based feedback and iterate to converge on the desired balance.
