Lowering springs on 991

[Pit991.1]

Hi guys,

I am considering putting lowering sprigs on 991.1 with Sport PASM suspension, either Eibach or TechArt (would drop the car by approx 10mm as already 20mm lower to standard Carrera).

Does anybody have any experience with lowering the car with springs only? Is it wort it at all, how would ride quality be affected if at all? Would it affect the future sale i.e. viewed as negative, "cheap" modification?

I can see a lot of information on US forums but not much in the UK.

Any opinions appreciated.
