Limit your Prodigy's rear chassis compression travel with a set of bump stops. These bump stops are 3D printed from a soft durable resin that allows for soft dampening effect that will not upset the chassis. The thickness also sets the chassis position as such that the side spring tension is not needed to hold the rear of the chassis up allowing spring changes to be used specifically for dialing in the roll/side grip of your Prodigy F1 & WGT-R.
These are specifically made slightly taller for the additional weight of these cars and should not be used in the Prodigy 12.
