i would put one on because it will last a good bit longer but a ninja has plenty of power even with the shim. we run a JPX 21 in our jammin truggy that everyone says is heavy and we just run 20%. i would get the shim and run 30% and it will have plenty of power.

The engine comes stock shimmed for 30%. do not add the extra shim. yes os stacks will fit... i like the 8mm

Run the extra (2 total) copper shim for breakin...Remove it after the engine loses pinch.
