Default Jag rear in ERA housing

Mr 0077 Here is what I have gone through to get the car to control wheel hop. I have the pinion angle at 3.0 and a shim under the trans to netrualize the angle and have no vibration for the drive shaft. The lower control arm mounts come in 3 different angles, 0,2, and 4 degrees for the control arms. Here is the problem, I have hard plastic bushing in all my joints. The lower arm pivot bolt does not always aline in the 2 lower corner mounts in the cradle. To adjust the rear toe I had to oblong the mounts and install GM shims between the control arm plate and the 2 bolts that bolt to the bottom of the carrier. This was a 3 hour job on the alignment rack. You need to safety wire these 2 bolts after you get the correct toe readings. I talked to a Jag dealer "A" and was told this is what they do on the old cars of the 70'&80's. You have to remember that toe angle and pininion angle is going to change when doing a burnout. If you want to do burn outs you can also raise the rear spring rates and raise the dampeners on the rear shocks. Raise the car in the back an inch will not allow the wieght transfer as much and make the tires easier to spin. A water bar on each rear tires with a 1 quart tank and little pump from a windshield washer kit will also save the drive train from shock when trying to light them up. Rick L.
