That RUF RT12 is just awesome mate! Seriously cool collection you have there
I'm really curious as to how you gel wit the Ohlins R&T's. I'm actually tossing these and JRZ RS1's up at the moment as I too feel that the damping is the biggest issue with the car. When I first got it I was actually reasonably happy with the suspension for OEM stuff, but after driving across some more roads in less than perfect condition it's really showed up it's high speed damping.
It seems as though they may not have quite had the impact you were hoping for?
