I won't cut up my DD truck to put a bar in, but can usually run all out at a private track rental. There's one track I go to that will let me TnT without the bar but won't let me compete and then again another track where I pushed my luck too far and tech won't let me back on the track without a bar even when I told them I'd slow it down. Lessoned learned...Never piss off a tech or the track owner. Plus its real simple for me to do a pulley swap to slow it down on race day.
