      Your pinion is higher than your transmission. It will likely vibrate. Raise your transmission as high as you can get it and reduce pinion angle. Ai least that is what I would do.

      Do I need to raise the engine mounts as well?

      Lowering the ride height with coilovers raises the pinion.

      No, just raise the back of the transmission as high as possible, leaving the engine mounts alone. Lowering the ride height in the rear changes the rear operating angle.

      I will test the product when it arrives. "How many times should I do it?"

      Correct. It will not be a big change, but it will be better.
