X2010 Suspension Tuning for Sarthe 24 hr

[SirAlanClive]

Does anyone have any advice on how (much) to 'soften up' the X2010 for the Le Mans 24 hr? It's quite disconcerting to drive for hours at a time, the car being so jumpy on that track. I know that the car requires as much contact as possible with the road because of the suction factor, but as Sarthe is mostly straights I could live with taking the corners slower if the total experience was smoother.
Thanks in advance.
