Just to add to that one you might want to experiment with rebound a bit. My first choice of racing is 1/8th Nitro Rallycross and we use rebound a lot more on bumpy and low grip tracks. Reason why is the initial damping (first few mm of the piston moment) is a lot softer until rebound starts to build. This gives you the best of both worlds and is very effective in bumpy conditions.
