They are discontinued. I contacted 4-5 places in US, even those that said they had /showed stock. But when I said did you know they're discontinued they said in that case they can't get them. Only place you will find some Is second hand on MR2OC but apparently it was going to cost US$175 to ship, that was last month.

The problem may be your 40 profile fronts. 
 
If you are looking for better ride, rather than Eibach Pro-kits look for some stock 92+ springs.
I have tried both with Koni's and the stock 92+ rode noticeably softer. 
BTW, they each have about the same ride height.
 

 
 Hi RT,
 I am working through problems with the car and now the focus moves to steering and suspension issues.
 Recently you helped me identify the source of some wheel shake, which will be fixed when I get home tonight to hopefully find some hub centric rings delivered. Yay !
I have a series of other issues due to modifications made previously, mainly wrong wheels and suspension. 
I want to check the alignment settings but for now I want to ask you about the post you made above in 2015.
 
I have some Koni inserts (set to softest) with some Eichbach Pro springs. I believe this lowers the car by an inch (?) which in itself does not please me, as I need help to get out of the car :o) but also I have read that lowering an SW20 can initiate issues around roll centre and therefore camber etc.  I like the idea of going back up to the softer stock springs as the Eichbachs are too harsh for Sydney roads, but my q is whether the Konis will lengthen that  inch ? and if so, surely their working range/travel is designed for one spring length than the other ?? seems odd.
I guess the fact that the Koni inserts are inside the stock strut probably means they will lengthen back 1" to stock spring length.  Lastly is there a diff between the stock front springs of a 91 to a 92+ vintage? I guess there would be plenty of sets around with all the coilover fans.
 Another of the issues I have is curious, besides the bump steer of these wide front wheel/tyre with incorrect offset, is that occasionally under braking the wheel is pulling to the left, sometimes. I am sure it is not the caliper or brakes and have check ed them, I suspect it is a worn bush or strut cushion that is altering the caster on one side, or something like that. I'm not really sure how to check those components. Any thoughts ?
 
 cheers,
Nigel

Oops now I notice your last line about the same ride height, doesn't that mean therefor that there is again only another 1" to the bump stop ? which I believe is the reason why lowering springs need to be much higher rated.

Hub centric rings have made a large improvement. No steering wheel shake until I use the brakes and even that seems less than before. Onwards and upwards...
