If it is not a big turn stiffening compression on right rear shock may help. Stiffening left rear rebound may also. All of these add weight to the right rear, some all the time and some when the suspension becomes active. Obviously the coil over and ladder bar adjustments are the easier to preform. Don't get crazy, sneak up on it.
Thanks for the reply.........i have another question when measuring ride hieght what do you use as a refernce point and also if the two back tires are at diffrent ride hieght will this affect the way it launchs making it go to the right.........i am kinda lost on chassy stuff never had to touch it before until i put more power in the car.........the car has 70 more horse and about 30 foot pounds of torque more.........but car only ran a little over a 1/10th faster as my 60 foots have went down from 1.40 to 1.45 i am guessing part of it is from going crooked and also my torque convertor is from my old motor and i looked at both motors dyno sheets and seen that my new motors torque is peaking later so it is affecting my stall which needs to somewhat higher..........old motor with no pill in 2 step with trans brake on would rev to 5300 rpm and new motor will only go to 5100 rpm new motor is peaking around 5200 rpm for torque........i have 32 inch tire and with the 5.14 gears i am at 7000 rpm probably 300 feet from finish line and car maybe gets to 7200-7300 rpm so it is laying down some so i am going to change the gears to 4.88 and see if maybe it will make the convertor work harder and pick up time and also not run out of gear on the top end.......my peak horse power is around 6600-6700 rpm........thanks sorry for being long winded
