Mainly bushes and spring plate mounts.... the things that degrade.... any pointers would be appreciated

I dont have the exact prices to hand but can give close approximates. All the bushes I have used are Powerflex, and all the mounts are standard Porsche
Bushes (Powerflex)
1. Spring plate bracket to body £40
2. Trialing arm inner to torsion tube £40
3. ARB bushes £40
Mounts, there are 4 mounts one each side for vertical movement and one each side for horizontal movement. For the later there are stiffer version for the 951 I bought these at £55 each (about £11 per side more than the standard ones). The ones for vertical movements had a very large price difference for the left and right one was £64 the other £140. Apparently the later is newly made stock and the former old stock.
Springplates, three options
New from porsche £285 each
Remanufactured from WPO germany (ebay) £200 for a pair
Refurb yourself and just replace the bushes (pig of a job) various suppliers for the bushes WPO or Powerflex or States £60
ARB droplinks
Porsche standard £125 each
After market adjustables £85 - £125 for pair
Standard non adjustable Sachs rear shocks £60 - £85 each depending where you buy (tip search on part number as they are often listed as 924 shocks but are the same for 944)
So, basically to do a complete refresh it aint cheap. But, if you want it to drive like a porsche and go round corners quick its worth it.
