The HPI racing clutch is a straight bolt on, remove the stock, and replace with the new one.

I haven't notice any improvement vs the stock clutch, then again I've changed, and tried so many settings, I don't no if I coming or going anymore.

I'm still using the clutch one the first hole, I'm tempted to cut it, and try the 2nd hole.

Has anyone cut it and tried different holes, any benefit, improvement????????
