For about as long as I've had them... November or December? Ran thicker oil with stock pistons then 2 stage recommend and went up from there. Went to 45/50 and came down from there to what suited me. Kinda how it find my setting is to go from one end to the other to know where within the range I want to be. Right or wrong, that's how I've found my setups from rc to 1:1 scale cars to moto-x to dh mtb.
Anyway, if I went past what rcshox says is its safe zone, I would not quarrel if it broke... it's not an expensive part. So it hasn't broke so far, if it does Marcus will see another order from me
