Firstly - can this please remain in the 147, 156 & GT lounge not Tuning & Upgrades, as it is mostly about standard suspension parts that I need to fit and how.
Right, as you all might be aware I'm removing the FK coilovers from my car and fitting it with Eibach Pro springs and Koni FSD dampers. As I am starting from an unknown position with the coilovers having been fitted by the previous owner, I started with taking them out, to see what was there, and if the new shocks and springs could go back in straight away, or if I would need to buy some standard parts to make them fit, which now appears to be the case.
Here is an exploded view of what I am trying to put in the car at the moment:
As you can see, there is the possibility of me needing two rubbers for each of the front corners, which looks like it is suggested by ePer.
After speaking to a very helpful bloke at EBSpares
it seems that the Eibach springs do not need a lower rubber due to them being 'sleeved' in a flexible plastic coating. But I will need a rubber from the top, and it is a dealer only part, due to it not being an item that wears out, needing frequent replacements.
As for the top:
It definitely needs a ring (how ePer describes it) made of rubber, to allow the spring to safely be compressed by the top plate that bolts under the arch.
The suspension fork what holds the lower end of the damper was looking worse for wear, so I cleaned it up and painted it in some spare time:
I also took these photos to compare the FK coilovers and the Eibach springs and FSD dampers that are replacing them:
As you can see from this picture the Eibach spring is much longer, and has more coils. It is easy to compress though, so should give a softer ride.
The damper shoulder that holds the lower end of the spring is higher on the FSDs than where the adjustable shoulder was set on the FKs, so if the springs were the same this should raise my rideheight by a fair bit. In reality, I expect some of the extra compression of the Eibach pro spring to reduce the increase in ride-height by a bit.
The damping part of the FK coilover is noticeably wider than the FSD. What effect will this have on its damping properties? The FSDs are noticeably softer than my coilovers, from when I tested a car fitted with them back to back with my own.
The rod of the damper is also longer in the FSD.
Just waiting for the rubber rings and protective damper-rod gaitors from Alexander Alfa Romeo in Thornaby before I can carry on putting it back together.
