Do you notice this in all gears? I don't have the vibration at 100mph in 5th, but if I do the same speed in 6th, I get the vibration too. Nevermind, I'm retarded, didn't notice you had an auto. Still weird though.

I didn't say -2 was for the drag strip. And yes, one degree can make a difference in vibration, I've been there..
The reason you buy an "adjustable" TA is so you have contol of your pinion angle, which for most people is used at the track. You see people at -3 or better is because the rearend lifts more dramatically when you launch hard especially on slicks which brings you closer to the "0" degree mark instead of the pinion actually going up to the positive side like you might do if your on the stock -2 degrees. For your daily driving, I like to go with the stock setting. Another thing, those dial indicaters they ship with the TA's are horrible and not that acurate, they could easily be off a degree. that's why I now have a digital one.. I'm just throwing an idea out there that I think has merrit for the vibration your talking about. Since all you did was change the TA right?

I say yes, because with the Spohn TA, your rearend probably won't move as much with just those poly bushings mounted to the center cross bar. What does spohn recomend the pinion angle to be? As far as the vibration goes, just re-check your pinion angle and try it to see if it helps, should only take ten minutes to adjust it. The angle is probably the only thing different than before the swap..
