Ok
I lowered mine by 30mm and it's a perfect drop, in my opinion, this is how the Stilo should come out of the factory.
I sourced the springs (Eibach) from www.motorsportworld.co.uk and they delivered them directly to my door for £90.00 (they list them at £145.00 but email them for a better price). I then got my independent local garage to fit them, they charged me £30.00 and the work took about an hour, 20 minutes to fit the rears, about 40 minutes to do the fronts.
My mate fitted the 55mm springs and the car sits far to low, it's on the floor and he has to watch every manhole cover, speed-bump, high kerbs when parking, etc, a nightmare, and taking passengers in the rear can be a scary experience too!
So there you have it, anything else just feel free to ask.
