Rick, I had to give the high roll center a try and I'd have to say that although it would seem that I should loose what little traction I get on our very bumpy parking lot track but quite the opposite happened. I went from the lowest roll center to the 2A all around with short links you had posted from the nats. Traction is still good but the car feels more responsive yet balanced and seems to respond to other small changes with a lot of predictability. I like it!
Running my leftover powers 36s from the Reedy event and people are amazed at how much better my car is hooked up than theirs. At night by the way, temps in the high 60s. Thanks for sharing this find.
