OK. Springs are all ok Maybe the light or something in the earlier picture, On the last 2/3 turns of the springs where they meet the top plate, the springs have a thin rubber sleeve over the metal. Hope that make sense. Also had a good look at the front set up, seem similar to the back, red springs and old OE dampers, they actually look worse than the rears. So I'm going to change the dampers alround, if its still bad after that, I'll go back to the orginal wheel /tyre set up. tx Lynn
2 litre fr shocks don't wear as quickly as V6's, just changing the shocks all round could work out expensive because if your springs are worn/weak you would have to pay again to change springs later. You could fit a smaller wheel/tyre combination with just new shocks & still not have the correct ride(too soft but hitting bump stops making it feel hard).
Changing the rear shocks is easy, quick & cheap. If you are then still easily hitting the bump stops(if they are still intact?) the springs are worn, if the bump stops are intact but the tyre still rubs then the tyre/wheel size is a problem(225s might not rub?).
I've just changed shocks, springs & r/bump stops on the V6 I mentioned earlier for a similar problem.
If you get the name & number from the springs you could obtain the unsprung spring length & check this to determine if the springs are worn(too short). You could still fit lowering springs, with new std shocks, they are a lot cheaper than a new set of std Alfa.
Test driving someone else's spider, as long as theirs is set up correctly, or borrowing another set of wheels are the two things I would try & do before spending a load of money.
I wouldn't bother fitting Konis or Bilstiens unless you really want to, you have been complaining of a hard ride after all.
