Mine is very mild and runs standard front TBs, variable rate rear springs (Kings - I believe are ultimately about 20% stiffer than standard, but don't have the specs), standard rear bar, 24mm front bar and koni yellow.
On the road it has mild understeer. On the track it has chronic understeer. Still quite quick and drivable, but constantly having the ease on the steering and feed in the power to avoid toasting the front tyres (which is a real culture shock for me coming from 105 which has the exact opposite problem).
I am now trying a 22mm front bar, but have yet to take it to the track (next event not until June
). Feels a bit more pointy on the road so hopefully will be better on track. Worry is that increased roll will cause front tyres to fall off their contact patches (we'll see).
If that happens, plan B is to re-fit the 24mm front bar and put on a rear bar from a 75 (bit bigger). However, plan C could be a roll centre adjustment - either front or rear...
