Had a chance to get out and wheel a little. Just received adjustable lower control arms will be installing them soon to center the rear wheel and correct the pinion angle at the same time.
You are right. 4.88 with 3.11 are adequate for what I do. Planning an LS swap at the moment and with 4l60 I will have slightly lower transmission ratios. Might do 5.29s later
Will post more in the next week or so. Rear bumper is renewed and flares go on next. Have a short trip planned for this weekend, and will take some pictures there.
