Sounds to me like you're spinning out because the tight middle is forcing you to use too much throttle to get the car around on exit. The LF spring would not be your problem, I'd say it's due more to too much spring across the whole front. Soften up the fronts to help mid turn, and take some rear% out to help rear pivot eaiser.

The spin coming off is the result from the slow middle corner speed of the push, try to take a little cross out and try to run front stagger as close as possible to even this should free the car and equel weight trans . good luck

On a dry slick track you should be running with less stagger than on a wet track..

I run a 3/8 high bank with 1 in. stagger in front and rear. Car weighs 3300 lbs. I run a 406 a powerglide in drive and a 5.83 gear
I turn 6500-6800 rpm`s with an 87 in. roll out..
springs are
lf-1100 rf-1300
lr-300 rr-250

rear 52%
left 54%
cross 51.5%
If i`m off the gas in the corner the car is tight and wants to push, but if i stay in the gas tha car is great going in and all the way through the exit.. try staying in the gas and see if that frees your car up..

my car was really tight through the middle and i softened the left rear speing and it fixed it immediatly. you can also take some cross weight out or soften the rf spring. basically anything you do to take cross weight out will help this problem. of course this is just an opinion but it works for me.

move left rear wheel out if you can should free up in and center and tighten off hope this helps. p.s. it worked for me

(handicapping gets worse the better you do and it gets harder and harder to get to the front the further they put you back)
