To lower or to anti-sway?

[Tessie McMillan]

I was going to take my sluggy little 80Q in to be lowered this week, but a
friend with an S6 Avant just emailed me: "Audis suffer from poor suspension
geometry when they're lowered; not enough camber to keep tire wear
reasonable". He suggested I get a rear anti-sway bar instead.

Any opinions out there? When I drove this car at the track mannnnnny years
ago (it is stock, as far as I can tell), I was nearly sea-sick from the body
roll. I thought lowering just a tad would help. Would an anti-sway bar work
better? What about a strut-tower brace? I'm going for cheap here, guys.

Thanks! (again with the hit n run questions...)
