I’ve never had it happen but he was in so lightly the second bulb went out, bumped in again and backed out again. When you hit the transbrake the chassis relaxes so some guys tie in the line lock to hold everything. I’m not talented enough to stage that lightly. In box class if you watch some of the dragsters when they back up the will stop in the prestaged light with their front wheels turned slightly. To fully stage they just turn the wheel.
