Need Traction

[84LX89GT]

If you are in a situation where you just don't want/can't install quad shocks (like i am becauese of the different mounting of my T-bird Turbo coupe rear) you basically need to address the weaknesses of the stock bushings.
After pulling out my control arms and looking at them it's a wonder how even quad shocks could cover up how bad the bushings are. At least in my bushings i could compress them quite a bit with just my fingers, which is scary because of how much torque/force is generated through the differential against the frame.
I would highly recommend at least polyerethane bushings if not control arms as well (you can get a set of MAC for around $200 for both uppers and lowers).
I'm also going to be running slicks with my Moroso drag springs and 70/30 struts which will help transfer weight to my rear tires.
As stated a good set of tires and subframe connectors will help a little bit, but the bushings are so weak they tend to defect and the quad shocks are there to dampen them (just like how shocks dampen springs, the quad shocks dampen the "springing" motion of the bushings).
Another thing that can cause wheel hop is incorrect pinion angle from ride height alterations or component wear (such as bushings). The farther off pinion angle is the more oscillation there is in a driveline and this can cause there to be a vibration under accel or even wheelhop while spinning the tires.
Hope this is of help, good luck.
