I have the Prodrive suspension set up in my car(Bilsteins/eibach)
Unfortunately One of the rear Bisteins is leaking.
Went to Performance Subaru to get a replacement but they said I had to buy the complete set,Springs and all.Is this true?
Or could I go to a bilstein dealer and get a replacement there?
Or does anyone know where i could get a single one ,new or used?
Would be very grateful for some help

You should always replace dampers in pairs. I suggest you go to your nearest Bilstein dealer, rather than pay the cost of a full set.

I had the rear Bilsteins on my imported WRX overhauled by Eibach UK.
Peter Kenney, senior Damper Technician, 01455 286524
Insert overhaul @ £55 per unit
Case overhaul @ £55 per unit, cases probably won't need done.
I sent both rears to him and the car felt much better when they were refitted, i hadn't realised the drop in performance.

Could you tell me the part number or the retailer reference/name of the Bilstein Shocks from the Prodrive WR Sport Suspension.
So the question is this how can I buy the same shock if I do not buy the Prodrive WR Sport Suspension.
Thank you.

Unfortunately mate the Prodrive suspension is made by... Prodrive and don't match with any other Bilstein/Eibach product. I have the part numbers (Subaru and Prodrive) but is useless to search it, believe me!
You could find the P1 shocks similar to the WRs and the Prodrive springs with the Eibachs, but not completely.
In real world it is a very good suspension but not for bumby roads and bear in mind there are two types, the WR and the professional one which is stiffer and includes also a smaller rear anti roll bar in order to reduce the excessive oversteer (wet roads etc).
Of course this is MVHO.
