964 suspension upgrade results
Discussion
Some may remember I thought I'd economise when replacing my old worn shocks by using a set of ex-993RS items:

This proved to be a saga of epic proportions, but at long last I have the car back from AmD, where Andy Fearn has put in a heroic effort to upgrade my (somewhat unusual it turns out) 964C2's suspension from it's thoroughly sh4gg3d Boges (over 120k miles) and Fulger aftermarket springs (anyone ever hear of these?).
After much general faffing, playing around with 993RS kit and problems with wrong parts supply from Bilstein we eventually managed to get the correct HD 'Yellows' to fit (rear mounts proved problematic as this is a _very_ early 964).
Matched to this is a new (and more expensive than I'd budgeted for) set of Eibach progressives. Andy has set up the car with AmD's laser 4-wheel alignment kit with a fast-road/occasional trackday bias - I'll post the settings if anyone is interested.
Just about every bush in the suspension has been replaced it seems, but then at 15 years and >120k miles that's no great surprise, except perhaps to my poor wallet!
Result: The handling of the car is totally transformed! The previous 'nervousness' has been eliminated - which was good news as when we had that mad bout of snow in London earlier this year as that translated to a several disconcerting moments of 70mph opposite lock merging from the M4 onto the M25...
Any tendancy to tramline at speed has now almost completely disappeared, high speed stability is of "hewn from a chocolate megalith" proportions and the M25E -> M11S 'corkscrew' is now faster and more reassuring than before with none of the sudden eye-widening 'sproiinngg' that happened before in the rapid R->L direction change.
All in all: one very happy (and poor) customer!

964C2
I spotted the Leda post on the Rennlist 964 forum too - after I'd already bought the Bilsteins 
However, I console myself with the facts that I'm not really at a level of experience where adjustables make sense yet, and Bilstein will revalve my shocks to custom specs for 50 quid a corner
I'm looking forward to hearing about peoples experiences with the Ledas, and am also looking forward to testing out the new suspension on track, probably Bruntingthorpe or North Weald...

Hi, this may not be relavent to the 964 but a friend of mine recently installed the 24 point adjustable coil over Ledas to a 944 Turbo. One thing to watch is that it took Leda over 4 months to manufacture the things, so it may be worth asking them what their lead time or stock level is for 964?
The suspension itself seems top notch. We had a play with the shocks set at level 4 (1 being full soft) and the car felt planted yet smooth to drive and soaked up normal roods with ease. We then set it to 20 and OMG
was that stiff. Roll, lift and dive were reatly reduced, but on poor surfaces the ride was incredibly harsh and we discovered new rattles and creaks that the car did not have before. The point I'm trying to make is that the adjustability was very noticeable and did affect the handling, it was not just for show or 'brag factor'
