I, like my old buddy Merls, have Teins on my R33 GTR. I actually have Ohlins on my R34 both height and damper adjustable BUT I actually prefer the teins and I have just received a brand new set of Tein coilovers for the R34 GTR which I am replacing the Ohlins with, they are that good. Having said that my Teins are HA's which are quiet a but stiffer than the super street so if your looking for a good street ride then I think you are going for the right option.
Also if you check the tein site (tein.co.jp) you will find the spring rates for all tein models.
