What are you planning to do with the car, and more importantly, what's your budget.
If you're talking unlimited budget, we should talk about some Penskes, JRZ, or Moton shocks with some Eibach ERS springs, custom upper mounts, etc. Then again, we're talking $1500 PER shock....
Teins are perhaps the best out of the box, but I would choose a rebuilt/revalved Koni on GCs with stiff Eibach ERS springs anyday. Besides, you can get the Konis rebuilt anytime you need, and you can get them rebuilt to be double adjustable if you like.
I had a set of race valved Konis with GCs and Eibach ERS springs. Bone jarring on the street, but damn did it handle on the track!
I am trying to decide what to do on the Miata, suspension wise as well.

Maybe Advance Design or I might just go the rebuilt/revalved Koni path again.
