It just seems a little unholy to not have a rear sway bar at all, and a number of experts (including FM) suggest having a rear sway if at all possible. Eventually I'd like to do the tried-and-true RB tubular front sway and stock rear sway.
The rear sway can almost certainly be made to work on tracks where, at speed, it's harder to get the rear to rotate. FM doesn't really have much focus on autox. What front do you have? I'm running no rear + the RB big f**k off "race" front sway. Tune the rear with springs if it needs to be stiffer, because keeping the drive wheels independent is good for going fast at an autox.
I'm planning on leaving mine disconnected all the time. Not over-steering on the street is probably more important than during autox. From a 'keeping the car not crashed' perspective anyway (I don't mean that as a dig at you, I mean that in a 'I saw my fiance get sideways on an entrance ramp when the turbo spooled up and I didn't really like it' sort of way).
Agree with all of that.
