And as a final update, finally had a chance to go hit up a bunch of gravel and dirt roads that I know well, and know the limits of the car on pretty well.
Final setup turns washboard roads into rumble strips, is the best way I can describe it. Interior isn't jouncing around all over the place, and places I felt like I was losing control even trying to get to 25 before are smooth cruising at 30 and skittish around 32-35 now since the whole car isn't being tossed about.
Also much more comfortable on a decently banked for drainage gravel-over-hard-packed-dirt road I know. I used to have to watch my line like a hawk on that stretch and the roughness of the road made it a PITA to feel what I was doing but now I could feel the whole car shift over and dive into the corner a lot more easily.
I really need to book some time at the local banked dirt oval, and go with someone with more experienced lingo, as I'm realizing I'm encountering things now that I lack proper terminology for. And someone with more experience will likely have good suggestions on how to tweak the alignment better than 'stock' does.
And that's the last update I'll stick on this thread, sorry if I spammed folks up a bit.
