Of course we don't know what the life span of FSDs are, my old Konis went soft in less than a year but at least I had the option to knock them up a notch (not that I bothered I just sold it
)
Will the FSD still perform well after 20k? The biggest flaw of my AD setup IMO is that its not adjustable so I can't notch up the dampers to cut out some of the bounce, will these have that problem, I suspect not as these are probably based on the right car in the first place.
It has always been my suspicion in the case of my AD kit that as it wasn't perfect from day one, its good but there are some ride quality issues with the rear end, I reckon they probably based the GT kit on the 147 not taking into account the differing weight bias hence spring/damper combo not 100% and why I got the rear end movement from day one, still loads better than a stock Alfa
