hi will
i still think the fronts are too soft your front bilsteins are gravel spec you need tarmac spec anything from 420/150 to a max 500/200 for the front
this will give you a good balance for the road and track use it sounds hard but isn't that hard
put it this way my rs2oo omk5 with 500/200rebound/ bump with 650lbs springs was still too soft for track use and the rs2000 is alot lighter than a cossie
