Dave,
You are running the same set-up in terms of springs and shocks I was with my ITC car with a locked and open diff. The only change I had to make was I removed one of my two Shine Tubular sway bars to keep it from oversteering to much. UnfortunatleyI found out what happens with to much over steer at NHIS.
As for driving style be prepared to do all your braking in a straight line because if you are not on the ags the car is going to push like a pig. It is very easy to drive once you get used to getting on the gas to get the car to turn for you. I loved the locked diff. even better than the quaife. Hope this helps.
Sam
