Here's my first hack at trying to get a compatibility list going. I'm posting it here for review. I tried to reference forum posts where part numbers and/or howto documentation are given. Please review and verify thoroughly if you would like to use this information and please don't sue me if it's incorrect. Specifically, killernoodle, FAZR6, jcaeser, segue00, 04Fizzer, DefyInertia, Randomchaos, wavex, if you have some input, I'd appreciate it. I know I might be missing some things that could be compatible with various R1 models (rearsets, shock) and some of the things that have been done mods that are not necessarily easy to replicate.
