I am lowered 2" all around making the appropriate angles even more difficult to achieve. After adjusting pinion angles a dozen times and having my driveshaft balanced by 2 different shops the solution to my problem was a new driveshaft from The Driveshaft Shop with a front CV joint. Haven't had a reason to take the car over 100 yet but smooth as glass up to that point now. It's a tough $800 pill to swallow but after paying the money I was finally able to enjoy driving the car.
Ive definitely considered it and just might bite the bullet. I just want to eliminate every other possibility first before dropping $800 on a driveshaft

a cheap way to test is to throw some "tire beads" in them one at a time. if it goes away or moves the vibe to a different speed/rpm/accel then you have a likely culprit
