When I hit the gas, my car pulls to the right... As soon as I get off the gas, it makes a dramatic correction and almost throws me into on-coming traffic... Even when I accelerate slightly, I can feel it... What should I check?

Damn good explanation, I was gonna take mine off until I read your post. They are squeaky as a hundred mice, guess they need to be replaced.Clarification: The quad shocks are there to dampen fore-aft motion of the rear axle on each side and are needed because the front bushings are so soft and pliant -- as they need to be to allow the 4-link to operate over its range of motion without binding.
If you've replaced the control arms with, say, Mac parts like these:
you don't really need the quad shocks because the front bushings are so stiff. But that raises another problem: binding. The control arms at the back are fixed at both ends to what are effectively rigid bodies. The uppers and lowers swing in different planes and being different lengths, they travel in very different arcs. Without compliance in the bushings to allow for these rigid arms fixed to rigid bodies at either end to swing through different planes and arc radii, you'll get binding and worse, you can put excessive stresses on the arm mounting points. You'll not likely hurt the lower control arm mounts in the frame nor the mounts on the axle. It's almost always the upper mounts on the body that get hurt because of binding. Add in the stress of drag radial launches at the strip and you may well be looking at upper control arm mounts tearing away from the floor pan. Since the upper arms are primarly the ones that give side-to-side axle location under the car, if they're going away you can get odd geometry changes in the back when you apply torque that can make the car rear-steer and be dangerous...
Get it up in the air and carefully check the upper mounts for tears in the brackets, broken spot welds and the like.
Well I just got the car off the lift and discovered some distubing damage! All of my bushings are shot! The lower control arm bushings took it the worst. One of them is actually in half. The other one is close to gone too. The upper control arm bushings are in the best shape, but they are on their way out. So, what do I do? Am I able to get replacement bushings for my MAC control arms? Or should I research a new set of uppers and lowers? Possibly change to a torque arm setup?? Any advice on where to go from here? It's clear that the MAC control arm bushings can't handle the power I have. I need something better. Thanks!!
It's what you call rear-wheel torque steer. That's what you get when you break stuff... It's the wierdest feeling EVER when the rear of the car steers and your car starts to "crab walk"....
I've got all kinds of terms you never hear of...
What is your main purpose for the adjustable control arms. I'm just trying to find the value in getting those. That is almost the exact setup that I am going to buy once I get the cash.
