For pilots who like to dial in handling, the Kyosho IFW437-10 Front Knuckle Setting Weight is a handy upgrade. Built for the INFERNO MP9 range, each 10g piece gives predictable front-end mass to help the car bite into corners on carpet or hardpack.
Placing weight on the front knuckle moves the weight bias forward, which can make steering more immediate and cut understeer. These parts are made to tight tolerances so adjustments feel consistent lap after lap.
IFW437-10 suits the full INFERNO MP9 family and installs quickly with stock hardware. That lets you swap weights between sessions to find the best front bias for the track.
