I'm burning my right rear tires up

I've been searching high and low for some help with my car, it seems like I've tried everything but I still have not hit the magic setup yet.  I run on a relatively flat quarter mile asphalt track in a super stock division.  My problem has always been loose off, not being able to power off the corners like other cars in my division.  I've driven a friend's car and it is able to get right off the corners like a dream.  My tire temperatures typically look like this: rf 140, lf 135, rr 140, rr 190.  I burn through a lot of right rear tires.  I'm careful to not spin the tires too and still the rr gives up.  I can be fast for a while, but my car always seems to go away and gets very loose on exit.  I run 55% left, 48% rear, 58% cross, I've tried increasing the rear split on springs from anywhere to 25 to 100 pounds, left being higher. My right rear spring is 200 and left rear is 250. I run about an inch and a half of stagger, although everyone else is able to run much more and still get off the corners better than I am.  I've experimented with dropping my front spring rates like Bob Bolles suggests to the 850 to 900 range, everyone else runs a 1600 rf and about 1000 lf.  Sway bars are optional, but I do not currently run one.  I can get through the corners pretty well until my right rear gets hot and them I'm loose everywhere.  I do run nitrogen on Hoosier G 60s, right side pressure at 26 psi and left side at 16 psi.  If anyone could steer me in the right direction I sure would appreciate it.  

First check your rear and make sure that it is straight.  A little toe-in is OK, toe-out is not.  Don't forget to check the camber as well.  Then make sure the rear is centered under the car and pointed straight, or slightly to the left.  You made no mention of what kind of car you're running, but the next step is to check the attaching hardware, bushings in a stock car, rod-ends otherwise.  Any slop must be corrected.  I'll assume that your axle bearings are OK and the flanges aren't bent, because they're fairly easy to notice.  If this all checks out, try softer compression on your rear shocks.  

Hey, thanks for the reply.  This is a 80 Monte Carlo.  I did check the rear end and it is square, everything seems to be fine with trailing arms, bushings, and bearings etc.  I'll check it for toe and camber.  This is the 2nd rear end I've had in the car and it's run just the same as the original rear end.  I run 3030 Bilsteins on the back of the car right now, and idea of where you think I should go with compression from there?  I do appreciate you taking the time to respond.  

3" of stagger sounds more appropriate for a 1/4 mile track.  I know that's pretty hard to get.  Try some dragstrip-style launches with your car.  If you are turning the wheel to the left to keep it straight, your rear is turning the wrong way under torque, correct this by putting new bushings in the left lower control arm.  If it launches straight, then something is holding up the left rear coming out of the turn.  Too much LR compression or too much reverse split on your springs.  You want the weight transfer to go to the LR on exit.  In this case I suggest swapping the rear springs before messing with the shocks.  Where are the frame heights and weights at for your car?  

Move the RR forward slightly, a little goes along way, also QA1 makes great shocks especially when Mike Naake gets done with them, put a 3-5 shock on the left rear, that will tighten the car up on exit, and a 4 on the right rear, also you should really think about putting that sway bar on
