Need a little help figuring something out
Just finished up my first autocross weekend of 2013 and once I ironed out all of the kinks and started to get used to my new setup, I noticed one thing in particular that is slowing me down and I'm not sure why my car does this? Not sure if it is something car setup related or something I'm doing inside the car.
I ran my GoPro behind all four tires over the weekend, the back tires on Saturday during the test n tune session and the fronts on my first two runs of Event 1 on Sunday.
Here's the video of all of them.

At about 1:58 in, you will notice that my right rear tire starts chattering and the rear looses traction. This happened with some regularity all weekend long, and it only does it on left hand turns...the back actually feels real good on right handers. I've got the front sorted out pretty well too, as long as I get it braked and settled before turning it, the front sticks pretty good.
Here's my complete setup as it sits now
Front
DSE upper control arms, DSE 2" drop 575# springs, Edlebrock IAS shocks (5 years old), everything else stock F41 stuff except poly bushings in the sway bar with
245/40/17 Nitto 555s
Rear
9" with Explorer disc brakes, UMI double adjustable UCAs and LCAs with Delrin ends, Hotchkiss 1" solid sway bar attached to LCAs, DSE 2" drop 125# springs Edlebrock IAS shocks (5 years old), 275/40/17 Nitto 555s
Here is the corner weights with me in the car

Here is my current alignment specs

It seems so far like the tires like about 34 psi in the fronts and 30 psi in the rears. Drive train is a carb fed 383 and new this year is a T56.
Here is some in car videos from both days also, I'd appreciate any input you guys have at all. I'm fairly new at this and while not trying to compete directly with all of the Evos and Mazdas out there, I would like to help me and the car run as well as we can without breaking the bank so to speak.

Here's a few action shots of the car from the weekend also.

Not to take anything away from all the other info here but first thing I would do is square up the rear end. Your thrust angle is at .06 which probably doesn't seem like much but that's enough to make a new Volvo Semi have a pull. The rear is pointed to the right so right hand turns are going to feel better than left. Try to get it as close to zero as possible.

Good luck and have fun with it tomorrow !
I hate when guys at alignment shops don't do a complete job, you can tell them I work for Hunter Engineering (the company that built the machine they're using) and I think they cheated you!
By the way my names also Lance!
