I have a stock wheel on my track bike right now with 6 swing arm. The spacers are not a problem, but if you use a stock rotor, you wont be able to use the zx6 rear calipar, as it wont clear by about a 1/4". The rotor is just a fraction bigger. So what I did was modify the calipar holder. If you have acces to someone who TIG welds aluminum it is a very easy fix. I will take pics tomorro and explain the process. But for now the one pic is obvious, thats how much you cut off of a stock axle. (the 6 axle bolts right in no mods). In the other pic the lowwer calipar mounting hole needs to get modified by a 1/4". You just cut out the bottom hole,leaving the bottom part of the sadle as a guide to weld the eyelet for the new location. It sound complicated but its not. Tomorro I will explain more.

I have evrything ordered to do your swingarm swap but I'm wanting to use my stock wheel. Besides shortening the stock axle, do I also need to modify the wheel spacers and if so, by how much?
