I have a Losi A or B spacer (the thicker one) on the inside of my rear shocks and 2 washers on the inside of my front ones. I also wind the bottoms all the way on until they bottom out i.e. not just using sidecutters in the grove at the bottom of the shaft and doing up until they hit that. I do that but then move the cutters up the shaft a mm and tighten, then another etc until they are all the way up. I would also ensure they are then the same left to right. You don't need to worry about damaging the shaft becasue the bit you hold with the cutters is covered by the spring cap when assembled so goes no where near the seals.
