Alright guys, I finally have a vid of my car running at RTTH from the outside (many thanks to leadSSled for the vid), and I am still learning how to get the most out of my current setup, but I'm hoping wiser eyes can help me go from here.
So here's the vid....I'm not at 10/10ths here because it was my girlfriend's first ride in the car and she was freaking out on me, but there's still enough that I think some good analysis can be made.

and here's what I notice immediately:
--the front looks to be having trouble transitioning from turn to turn and recovering after a turn--there's a little extra bouncy-bounce after each major front suspension event.
--there's a lot of body roll in the back (so much so that both tires were scrubbing, hence the ridiculous jacked up stance to keep the fenders off the tires).
--The back is sticking all day long and the front is pushing.
Setup: ridetech shockwaves with their newest shocks (master series double adjustable), but the non-remote reservoir ones. SPC ucas. Ridetech lcas. ridetech airbar rear, prodigy bar brackets, air ride front swaybar, no rear swaybar.
alignment: -.75* camber, 5* caster, 1/32 toe per side
shock settings: front 95 psi, rear 85 psi (110 in this vid, but normal setting is 85), I lost my actual setting log on the shocks (will check my backup files tonight and hope it's there) but the fronts are at 3/4 to 5/6 of max compression, 1/2 to 3/4 of max rebound and the rears are at near-max to max compression, around 3/4 rebound (compensating for rear roll)
Based on what I'm seeing:
--a rear bar would help with rear control, allowing me to stop overcompensating with too much spring and shock in the rear.
--more camber would help with the understeer
--I need a little bit more rebound on the front? This one I'm least confident about. More compression and spring too? Or even more bar?
Does this sound right to you guys? What else do you see?
