Vision Racing have introduced this motor centering kit for the Losi XXX-SCT and all XXX series chassis that use the black ball differential transmission. The kit shifts the motor to the right 3mm or 6mm to help cancel counter torque effect and improve left to right balance. The set includes two 3mm quasi-ply carbon fiber plates, longer screws and 6mm slipper shaft spacer. Read more and see some photos of the kit installed via the source link.
