Okay, I am going thru this slowly in my mind......the front is not "limited"but even when you jack it up, it only drops 2.5". Which compound rubber are you running and what is the springrate "and" the Caltracs rated at? You have good stuff under there. It appears the tune is not right and I wish you could shock the tires harder but if the rubber ain't there, it ain't happenin'. Could you spend some time with this car this week and find bar angles to determine instant center. Find a way to get the travel you need for your preffered front lift to help the rear. I am not going to go into squat and anti-squat at the rear yet because it seems it's not loading it up yet. If you could scale it for corner weight, great, if not don't worry about it now. Everything you mentioned for components can work and are very adjustable, don't give up and start back to basics. Tire compound is a good thing to know. Sometimes using your tracks to back up into works great and sometimes backing up into the previous run's tracks makes the thing hook super well. Depending on the compound of your tires.
