The Inmotion RS Jet has got very noticeable play in it from the factory. Fix it, starting with this set of shims from PEV Outlet. On the JET, the support bars that run horizontally and vertically through the rear suspension housing are just too small for their holes, allowing the adjustable slider to knock back and forth. Use this kit as shims around the 2 smaller vertical support bars, and through the suspension eye hole. Combined with plumbers tape, a thin copper strip, or even just a shredded aluminum can  in the threads of the main adjustment screw, and you can completely eliminate the play in the rear suspension housing. Bushings are made on-demand per order, and take about 4 hours to print. They are 3d printed using blue PETG material.
