Red face help with wierd vibration!!!

hey guys i need some help figuring out this vibration.
ok my car is a a4 98 z28 with 3:23 rear.
the car feels fine when wot and just cruizing on the hwy but if im going around 75-80 and put it in 3rd on the gear selector and hold my speed i get a decent very noticable vibration but if i go wot from that speed its fine.
i put it on a lift and it all looked good.
could my drive shaft be out of balance?
