About the bottom plate...
I'd love something similar to the NTC3 RPM bumper for the Xray... saved me a fortune in parts for my TC4, granted the Xray is tougher, but where theres a wall theres a way....
I use green slime on all the shock O-rings, only issue I have is that I think it makes the bleeding abit more time consuming as the seal the greenslime makes is pretty good.
