I was wondering if you can shim the compression spring on the
formula RER clutch? There is already a plastic shim between the
cam and the spring, could you put a thicker shim in there to add
tension to the clutch?

Has anybody tried this? Dynamo Joe???

sure you can, if you remove it some sleds like it some don't but for the sleds it works on you will see an increase in top end.
