Ok fellas I'm new to this so bear with me.We have a 68 chevelle chassis and over the winter we have set it up(with a lot of help from this site)we are running 3307lbs with a 900lf 1100rf 250lr 225rr we have 53.6% LEFT 49.2% CROSS and 52.4%REAR and 100lbs left rear bite the car has a torque link and it is at 12 degrees up in the rear the lower control arms are 12 degrees also we have 1/2" stagger in front and 2 1/2" stagger in the rear. we practiced for the first time and the car was great the track was wet and very tacky and the harder we drove the car the better it handled then this week the track went dry slick and the car pushed bad seemed like it would turn in and then push in the middle and be loose out.what would you fella's try. the track is 3/8 mile high banked and we run racing tires, thanks

What kind of tire pressure are you running on the dry slick? I would say to put more lr bite in it when it drys out. Maybe reduce the stagger in the rear. I would also maybe trying a 300 in the lr and like a 250 in the rr(if you have springs). Just a few things i can think of. Hope it helps a bit. Good Luck!!

Everything looks like it ought to be pretty close.
I pay attention to shock travel and tire temperatures too. Do you have any of that information.
Might check toe settings and especially look for a bind in the suspension. In the wet tacky conditions you were probably throwing the car into the turn, in the dry you drive into the turn.
Your springs are good and soft, which is good, but maybe laying over on the RF in the middle of the turn. Bad push is slow, then the driver is really giving it the boot to get out of the corner causing the loose condition.
Fix the push first.

I would say that you have to much stagger in the car the rear end is trying to pass you comming off the corner OR spinning the wheels comming off making it seam loose does it push every where on the track in the middle as far as being high or down low cause a push in the middle of the corner will make it loose comming off

One more thing to try is put more cross in it that will help take tyhe push out of the car in the center
