No, in a tight autox you want the tail loose to help turn that heavy beast between those cones. And your are under 60 mph so it's more forgiving if it gets unstable.
I can understand that. I'd say that with that stock front bar and the addition of the rear bar you must have been near tail happy - makes sense that you'd need a bigger front bar in that case.
Drove it for almost ten years like that. Wasn't bad at all. I drove it like a madman around town. It's on higher speed corners on a track it's where it would get tail loose.
