My car has done 68k miles, and is almost certainly on the original suspension. I would like a little advice on which of the following options is most recommended (And if anyone has any experience with any of the options). My car is only used on the road, so I am not wanting to spend too much cash on coilovers or bilstein B8's etc. All going well, I would plan to hold onto the car for a few years yet so am prepared to invest in more parts if it is definitely worth it.
Option 1: As long as shock absorbers are not damaged, replace only the front springs with Eibach's and have the rear beam lowered to match.
Option 2: As option 1, but upgrade rear shock absorbers whilst they are lowering the beam.
Option 3: Eibach springs, new Bilstein B4 front dampers, new bilstein rear dampers, lower rear beam.
Option 4: As 3, but also change to larger diameter rear beam torsion bars (306 estate etc.)
I know this has been covered before, and I have read through other threads on the subject. I guess my question is whether there will be a noticeable ride difference between (1) just changing the springs and (2) replacing all dampers with new bilstein equivalents aswell as the new springs? Also, is it much extra work to change the rear shocks and/or torsion bars whilst beam is being lowered?
Thanks!
