Steering wheel/seat vibration when braking and not braking!!

NOLA

I have checked the forum for an answer. None are solid answers IMO.

I have a 2010 Nismo (stock suspension, wheels, stock akebono, and factory size tires) and I have steering wheel and seat vibration at certain speeds when NOT braking, and while braking. The car pulls right as well when braking. Here is what I have done to try and fix the problem:

New tires
Road force balance
New rotors and pads
New brake fluid & several bleeds

To answer any obvious pieces of advice:

I've ensured tire pressure is always the correct pressure
I've had several alignments and tire balances.
The old rotors/pads had this problem and now have been replaced.
New Rotors/pads were imbedded properly.
Pads have even wear as far as I can tell.


What is next in figuring out how to fix the steering wheel/seat vibration under braking and not braking? As well as the pulling right under braking.
