The GPM MIF009F front arm plate is a CNC friendly aluminium upgrade engineered to stiffen the rear gearbox junction on the Kyosho Mini Inferno ST. Precision machining reduces flex and improves load distribution across the gearbox mount, extending service life of mating components and providing a firmer platform for suspension tuning. Designed as a direct fit, the plate maintains factory mounting points while delivering measurable gains in structural integrity.
