Picked them up used off a Kumho race car, got a good deal. New they are the same price from everywhere really £340. Fitting is very simple, just unbolt the old one and bolt the new one on. I did end up having to undo the rear shocks and take the springs out to get the drop links in and out but that's hardly a major operation. If you intend to use the existing links then use a ball joint splitter to get them off the old bar, they were stuck on TIGHT. Easiest to take the nearside part over the exhaust pipes toward the centre of the car. Do it with a helper if you can, it's an arse on your own.
Anyway, I did take it out in the end. Lets just say the car is on another level now, feels super stable, like it's really unlocked the potential of the suspension and tyres. Hopefully I'll be able to take Redgate without the catastrophic power oversteer I had last time. Superb mod and I'd recommend it to anybody who wants a serious handling E36.
I'm still running it on a supposed junk setting too (hard rear and soft front) so there is more potential in it to come, i'll change the setting at the weekend.
