Ok, because the only thing better than not knowing what you are doing is not knowing what you are doing, but with technology to quantify your ignorance, I have purchased a Quarq ShockWiz.
I now need some advice on volume spacers - which ones do I need for:
Fox Float Performance EVOL SV, 115mm Travel
Fox Performance 34, Float, FIT4, 3Pos-adj, 120mm Travel
And what tool/s do I need to get into the shocks to fit/change the spacers?
