MPSS (of course!), but then it was on these from day one (or day two, after I picked her up). The car was absolutely fantastic on the OEM suspension in terms of feel into a corner, there was just too much body roll hence me changing it for something better. Well, and the fact that 100k dampers are clearly not going to be as good as new ones anyway. I was able to walk away from my mate with the Gallardo in Wales such was the confidence I had in the car, but I've really struggled to get that back ever since. All my little tweaks (adjusting the front ARB, adjusting the balance front to rear on the dampers, adjusting the toe/camber) have helped, but I'm still not there and I'm fed up of faffing
It's the one drawback to doing too much at once: You don't know what caused the 'problem'. I did wheels with spacers, dampers and ARBs at the same time, so I don't really have the time to fiddle with each one to get it right.
Funny you mention the 888Rs though, as I'll be getting a set for mine once the MPSS run a bit lower. I suspect it'll be superb fun
