Mick, we were tuning our launch a little at the weekend at the pod (not a good thing to do when your running in brackets I know) We had 12.5 psi cold and we need more looking at the photos. We got it down to a 1.37 when the front touched before the 60ft lights and 1.48 when they didn't. Car wants less ext damping and more compression damping at the front along with more rear tyre pressure, lots of wadding on launch and darker at the edges on the contact patch.
We're just creeping up on it as a friend of ours with caltracs got all 4 wheels off the floor this weekend and had some damage
