Bin fighting this all year. Only difference from last year is the flywheel. Last year and years before I had been running an aluminum wheel. Found it was warped over the past winter. Installed a steel wheel which is about 20# heavier. Now the car blows the tires off at launch. I've dropped my 2 step all the way down to 3K from 5K. I've dropped tire pressure down from 15 to 12 psi. I've loosened the rear shocks from 9 to 7. I can't get the car to plant or even control the amount of off line spin. I'm pretty confused at this time..

car weight with me in 3926#
slicks 29 12.50x15
gears 4.56
Rancho 9 ways out back
90/10 up front
Mopar SS springs

Any suggestion?
