Vibration when accelerating between 45-60 on 1995 BMW 525i

I have a 1995 525i. It vibrates when I am at speeds between 45-60 then it stops vibrating and returns when I am slowing down between those speeds. I have replaced all 4 tires with balancing and laser alignment. It has new rotors and brake pads. Any suggestions?

Check your flex disc in the drive shaft, there is component called a 'hardy' disc that can vibrate at certain speeds, it then causes the whole drive shaft to be imbalanced and that can cause vibration. That is one thing that I would check, I have replaced several.
