I'm running Caltracs in a 11.0 foot brake car. When setting up the Caltracs, they are preloaded against the spring about 1/4 turn. When foot braking, bringing the rpm up, "preloading" the chassis, doesn't that negate anything the Caltrac preload is doing? Don't the Caltracs get preloaded when it's footbraked with rpm's? I know what I'm trying to ask, I just hope the question acually makes sense.
