I use to run a rear sway bar at the indoor track's older layout that had a large flat sweeper. It gave me more side bite (corner speed) and let me get on the power sooner. Also helps in chicanes. Been running outdoors w/o any but I may try it...I've just been working on my throttle control thru the high speed sweeper..but it'd be great if I didn't have to lift as much to get it to turn.
