Thanks for your inputs Weasel, 40/60 might be just right.
FYI, I run mostly trails and have fun on the rocks. I'm riding on 33's with ome leaf pacs, coils (zj), and long travel shocks. I want to keep my center of gravity low and maintain a good balance of compression and extension on my shocks. I think, with the right sized spacers on the coils, and the right shackle in the back I might be able get to the desired ratio of shock compression vs extension. I'm just curious what might be. I'm thinking 30% for compression, which would be around 3.25 inches of up travel, and 70% for droop, which would be near 8 inches of down travel. Is that too radical?
I'm wondering what others run, or if people don't concern themselves with this.....just get the lift they want and forget about it.
