I have wondered that too, I just bought it the other day and it is comfortable but it is not great on corners and I struggle with traction even on straights. I have lowerred it with the 250 lb springs and the back is stiffer and down 40mm today too so, if after driving it around for a few days, if it feels alright, taking on the track with just the 250 lbs is not unsafe? Basically I don't want to conme off on every corner!
I have also put on better wheels to try and help traction, could be I am usewd to having to boot the 1.4......
