Shimming the stock rear shock has minimal effect but it is an improvement. I had GMD Computrack in Atlanta set up thge chassis on my RC51 which involved a Penske shock and an adjustable shock link. Seat height is raised 25mm. The result is dramatic improvement. Moriwaki make a link but it is not as a big change as GMD mods. My RC51 is as nimble as a 600 without significantly effecting stability.
