Yep, I run DMS 9kg front, and 5.5kg rears. Interestingly for the 32 GTR this is their (DMS) "targa spec" rates with valving to suit. So more of an all-rounder than a straight circuit setup. You certainly can't afford it to be drifting or spinning wheels in a Targa event I assure you.
And it feels very sure-footed - still with some good compliance.
As Roy points out, a good deal has to do with valving too. I think a lot of people try to 'over dampen' - using the shock to 'stiffen' the ride.
