Quote: Yep I understand what you are saying. When I was running 11.0's I had 0 preload on the bars. I took them down to touch the springs and then tightened there. This worked the best for me. When I put preload to them I lost 60'.
Ours has a thickness of a nickel airspace between the spring and crossbolt (static w/driver). When footbraking, it closes up, probably when it is just put in 1st gear.
That's what I was thinking with the air space. If the Caltrac bar is preloaded to begin with, wouldn't that be the same as having it way tightened up on something like a transbrake car?
