Gmade does make some really great shocks. I think what they lack is softer spring rates, almost all of their springs are too stiff for a light rig in my experience.
This has been my experience as well.
The GMade 85mm XD diaphragm shock is fantastic. Smooth like butter though pretty large in diameter for a scale truck. The GMade RSD shock I could be nice, but the springs are maddening with how stiff they are. I still need to find a softer spring that fits them.
