Did u do anything to your suspension? Am seriously thinking of switching out. It works fine for daily runabouts but once for serious sustained highspeed, it is not satisfactory. Ah yes, did you order it from US? They wanted USD4.6K for that & a lot of money for others like their diffuser etc. Am thinking if the one from Techart works. Someone posted a chart on another site which says that there's 18Kg rear & 12kg front @ 240 which I thought isn't a lot.
At 280kmh the car is solid and planted. I don't know if changing the suspension would help... areo dynamics in the right places would probably be more effective.
