My car is very similar to your setup (my RF spring is 1100, the rest are the same) with the only real difference being my rear weight is 'only' 49.7%. I run at a dry slick 1/2 mile on 8" Hoosier RC4s.
I called Bilstein earlier this year and spoke with a tech. He happened to have run a car & track very close to what we run on. He recommended AK3030Rs for the rear, AK4040F on the LF and AK3050F on the right front. THe first 2 numbers are the rebound and the 2nd 2 are compression. So the 3050 is a super heavy compresion and med. rebound. I must say I've been very happy with them so far.
Daymotorsports sells them, or find a part store that orders from Motorstate Distributing. The AK3030R, AK4040F and AK3050F are all in Motorstate's system now. I was the first person to order them since they're a relatively new part number. They have to be drop shipped from Bilstein, so it takes about 10 days for them to arrive. I won't say what I paid for them (cost from Motorstate) but if your parts guy treats you right you can get them for about the same price as the Afco site sells theirs (within a couple $$$ anyway).
The tech at Bilstein said the other shocks they sell work best on Asphalt cars and the numbers above work best on dirt cars. Espeically on slick tracks.
Oh.. and also check your tire temps. If the LF+RR is higher than the RF+LR, add some cross or tighten up the sway bar. The advice I was given was to shoot for the RF+LR to be 20 degrees higher than the LF+RR. At first I was 30 degrees the wrong way and now have them about equal.
