Bought new springs and going from .46 to .48 as recommended but they came with spacers to equal out the length to the stockers. If I put the spacer on top of the springs the stock washer/collar slides into the spacer but does not reach the actual springs. The washer/collar previously sat down into the springs to keep them centered in the tubes. So does the spacers go on the bottom of the springs? Also race tech suggests 110mm oil height and stock is 132mm that seems like a big difference. I was bottoming easily with the stock springs but they were definately too light. It's a 2011 any oil height suggestions? I race c class enduros and hare scrambles. I need to get it back together right before my race this weekend!
