FSDs\ Eibachs are not cheap, but cheaper than most decent coilovers is the perspective I have formed from the threads. You may have read my report having had this kit installed (not by myself), but I do not know what the problem is with the front v. back clearance- mine have settled nicely (and probably will do so more), may have something to do with parking it on a downhill drive over a period of time, who knows.
As for the concerns:
- I drove a Brera S on Eibach springs for a few months, that was far too rigid for my liking, the FSDS\Eibach on the GT are more supple, but tighten-up well round corners, under acc-\deceleration, braking and so on, but less inhibiting and just SOLID.
- the FSDs\Eibach give superior comfort to STD setup, no doubt it's well worth the long term investment in the structural integrity of the car
- like the V6, I imagine the heavy 1.9JTD engine will work well with the better support at the front.
- I drove my GT for 50 miles everyday to work on this setup, for 3/4 year, it was divine. However the roads are now so bad I use my older 156, but it still hurts a lot to have to drive over the poor roads round here.
- you will be amazed at the improved control with the high torque of the JTD, however, if you do not already have the mechanical Q2 this would be advised as a first on the shoplist, since when you do a suspension upgrade you will feel and appreciate the different benefits of the upgrades.
Just my thoughts, I am sure there will be some different opinions.
