Not that I've any experience with that.
If I'm not mistaken, the launchbar code takes the position from the ground cache, but the carrier position is not updated there neither. So it does extrapolation anyway. I tried the same thing already but there was much jitter also. I guess the launchbar isn't that sensible about the jitter, but the friction "spring" is only 1cm long and the jitter is bigger than that. So the dynamic friction kicks in and the sliding comes back.
