I have a 32 GTR with Tein Monflex coilovers. They are a lot dearer than Tein S/S but are well worth the extra you pay.
If you are looking for compromise between track and street then these are a good option.
My car is set up for track, and i,ll admit doesn't do as many track days as it should, but still sees a reasonable amount of street use.
On the street i set the EDFC on the softest setting and the car is great (don't need a kidney belt).
However the whole balance of the car comes down to the bars, and the EDFC just allows a little more comfort when the car is not at the track, as well as allowing adjustment on the day-depending on the track and the conditions, tyres ETC.
If you are street driven over 90% of the time and set the car up so, you have a lot on your plate trying to adapt the car at the track - it really needs to be the other way round.
To be honest most of the cars i see these days that have had suspension mods done (unless they are serious) look like bouncing bricks on the road (and very uncomfortable as well).
If your streeting most of time go for a softer bar and coilover setup - and your ride will pay you back in kind, however if you want to run at the track - then spend the money and live with a little less comfort on the street.
Cheers!
