I have the TEIN setup on my 92. When I first installed it and drove the car (for about 500 miles) all I could think of was "God damn this thing rides like a brick on skateboard wheels"...
However, that was due to the fact that the suspension comes at max "firm" setting out of the box... after taking 30-45 minutes of "tuning" and driving my car up and down this semi-bumpy road I got it dialed in to a nice, comfortable "bounce" level.
Then I took it out and drove a twisty road digging into the corners. Made a few more minor adjustments on the dial and now Im very happy with the results.
The TEIN is really easy to adjust using a little tool, and the adjustment levels are amazing. It rotates 3 full turns which is about 24-26 "clicks".
After adjusting it out, I found a nice level that is suitable for the street but still provides great support in the twisties.
On the track, im sure my settings would change a bit, but overall Im happy with the performance and would recommend them to others.
The price tag is a little more than a conventional "springs and strut" setup... but you know what they say... you get what you pay for.
