Got bored working the Test & Tune last Saturday (we had a lot of organizers and a bunch of no-show competitors) so another organizer and I decided to tighten the rear sway bar on my Mustang a notch on each side and see what would happen. I thought the car felt pretty neutral before, but I wanted to see if I could get it to rotate a bit more without making it too "loose."
Dang, I should have played around with those adjustments sooner. I have both ends of the rear bar at 2/4, and the car feels perfect. I can put that thing exactly where I want it, and it seems just as neutral as before, but with a slight tendency to predictably oversteer as opposed to understeering.
Based on looking at pictures that some people posted to the club's forum, I seem to still be getting an appreciable amount of body roll, however, especially upfront. But I'm hesitant to tighten the front bar any more (currently at 1/5), because I really like the handling. I'm currently running only ~1.6* of camber upfront, though, so I'm thinking that increasing the camber will give me a bit more cornering grip without changing the overall dynamics of the car.
I also have to redo the bushings upfront this winter, because I have an early build 2011 with the early-design hydro bushings. These things were revised 3 times over the course of the '11-14 model years because they keep degrading and squeaking. The final solution is not only a new bushing design, but also a heat shield over said bushings to keep them from baking from the heat of the nearby catalytic converters. So I'll be swapping to the new control arm design and upgrading to taller ball joints and a bumpsteer kit while I'm at it. Since it'll need an alignment at that point, I'll increase the camber to -2.2* or so. Thoughts?
