Ok, to demystify some of the information I have been gathering up over the last few months, I want to try to clarify backer shims. I have read that : *Backers limit the travel of shims above them to some extent *Backers on the other hand allow more travel of the shims above them OK with that being mentioned, lets look at two similar fork stacks: Stack A: 24x.1 (3) 12x.1 22x.1 20x.1 18x.1 16x.1 14x.1 12x.1 8x.30 base plate Stack B: 24x.1 (3) 12x.1 22x.1 20x.1 18x.1 16x.1 14x.1 12x.1 8x.30 12x.1 16x.1 base plate With the addition of the two "backer" shims in stack B, would the face shims in stack B open farther before touching the top out plate under the 16x.1? Reason I am asking is because I have seen different set ups listed where some tuners add in backer shims and say that this will have a different effect on damping charachteristics. I'd love to hear what you guys are going to say! BTW, Restackor will not work on my computer.
