Read various write ups on this and since purchased a set of rx1 skis. I assume the spacers on either side of the spindle bushings will have to be eliminated? What do u read for carbides? Writeups say to make an additional spacer under the ski mount, my rx1 carbides barely have any thread left to be able to do this... Just want to know what I am getting into before pass point of no return, modifying these skis
