Hi Mark,
First let me address your statement about the rear not settling after a rise.
Remember, due to where you are sitting relative to the polar moment you are going to feel that the front is settling quicker than the the rear as you are quite a bit aft of the rotation point. So take this into account as you look to set up the chassis.
The rear spring rate on your chassis is normally 325>375 depending on the track. (The slower the exits the higher the rate.)
I do not know what dampers Dave had on the car. But it sounds to me that the bump rate on the rear might be a bit too high or you are being fooled by the dynamics. John's recommendation of a good set of double adjustables is a very good one as you can dick with the settings and figure out what is going on. (Or you can go so far out in left field that the car becomes undrivable. Has happened to me a number of times.)
Secondly, The web site setup info really speaks to the SWB chassis. The LWB chassis was designed for a 4in. front and a 5.5in. rear ride height. In other words, the geometry (Camber curves) are optimal at that ride height. And as an aside, if you use the undertrays, it is the good for underbody flow and does reduce lift. (But 3 and 4.5 is better for aero.)
The best thing for you to do is to give me a ring and we can discuss what you are feeling in the chassis and I can give you setup direction relative to that info.
Please understand that I like to get feedback on the setup and development work that you guys are doing out there.
After all, that is why I did the car. For folks like you to have fun and go fast.
Send me an email and I will give you my numbers.
