Roll center isn't actually a very useful term IMO. Just like we have geometric anti-squat and anti-dive, I think it makes more sense in terms of geometric anti-roll. When considered in that context, the measurements and calculations follow suit. Below ground is pro-roll and above ground is anti-roll. Much like the other anti's, it's also possible to keep raising it beyond 100% anti-roll.

Thank you for all the detail. I'll try to make sure to return to this thread when I am testing, and add a bit more data.

I'm going to be running a 4L60E(I know) at the challenge, but thank you for the info, it may be useful in the future. I'm attempting to get a cheap converter that will give me a few hundred extra RPM stall speed, but there is a chance I'll have to run the stock converter. Rear axle ratio will be 3.42 or 3.73.
Thank you everyone else, too. This has been a good learning experience so far.
A potential stupid thought occurred to me. The S10 Xtreme has a horizontal hop shock running from the rear axle forward to the right frame rail. I am wondering if that could effectively be used to add a little preload to the right side for the drag race. I am assuming there'd be no overall advantage to it during the autocross, but it could simply be unbolted.
The main reason I thought of this was that it would only hit the challenge budget for a total of about $15 for a replacement shock, and a few inches of MIG wire to move the axle bracket to the new rear axle. If I have the time to install it, I may do it just to see what happens during testing.
