You don't need drop spindles with larger torsion bars. You should be able to just set your ride height with the adjusters. Larger bars = less suspension travel. So, if you match your torsion bars correctly with the ride height you want, you don't need drop spindles screwing up your suspension geometry. Your car sits pretty low, so I would consider going with bars on the larger side of what I suggested. At least the 1.03's. Although I would imagine that your current set up bottoms out all the time if you have /6 bars and the standard spindles now, so anything would be an improvement.
I use Helwig sway bars on my Duster. The front is a hollow bar similar to the Hotchkis bars but at half the price. The rear is a solid bar, but is adjustable just like the Hotchkis bars. Again, at about half the price. I think they work pretty darn good.
