So after some horrible times with this crazy engine combo, I've realized its time I get serious with the rearend mods. Right now I have the stock sway bar, new rearend bushings, eibach lowering springs, BBK upper/lower control arms, and 26x8.5 slicks. The car has 2.3 60's and breaks traction in 1 and 2 and sometimes 3rd. If I get on it on the street at speed it breaks free too and gets a little sideways. I know I need more tire so I'm stepping up to 27x10.5 hoosier to keep me in 3rd in the 8th and give me more footprint off the line. As for the suspension I need to go adjustable to fix the pinion angle but what should I get. I was thinking I only need the upper adjustables with the solid links. Do you really need both upper and lower adjustables to setup the rearend? I was thinking bigger tires, same lowers and adjustable uppers should do the trick. What do you suggest or know that works. Also, do those panhard bars helpout.
