konis
Koni's are a good shock if the valving is right, just don't bottom them out or you will smash parts inside of them (spring choice and bump stops are critical). I have found that the standard off the shelf konis are allright, but after having them revalved specifally to suit my cars and my needs, they were great. This was on both an A spec vr4 and an 323 familia.
Although,,,,,,,, on my Gemini rally car, the rears required a reco yearly, A fellow gemini competitor has been using Bilsteins for the past three years without a rebuild yet. I have had the Bilsteins for one year now and won't look back (anyone want some koni's for a Gemini?), The Bilsteins have better traction, more travel and a softer and more controlled ride.
