This started happening a couple days after I replaced my 16" kosei k1's with the 18" v710s I got from VMR.

So last saturday I lifted the car up and replaced
~Driver side Control Arm
~Driver side Control Arm Bushing
~Driver side Inner & Outer TieRods
#Checked stabilizer link (great condition)
#Checked wheel bearing (great condition)
#Checked sway bar (great condition)
#New Yokohama tires and VMR wheels (just mounted and balanced 3 weeks ago)

I am out of options and dont know what the source of this problem could be..
However I am suspicious of the Steering Rack/Column.

If any of you guys experienced a similar problem please help me out. I am going crazy as I just spent another $300 in parts. (second time i replaced a control arm and a bushing in 10 months)

What could it be?
Actually mine did that after I got my rack re done.

First, DIY some things, pull apart your wheel and brake assemblies, it's not necessary to clean up the Calipers and pads, but it is something I would do while your there, most people use a wire brush, I used a Bench Grinder with Buffing attachment then used a wire brush for the other hard to get to areas.

Then with Brake & Parts cleaner and the wire brush, clean all contacting surfaces, Hub surface, both rotor surfaces and the wheel surface, ensure a nice, clean smooth surface, and reassemble. Obviously do this to all wheels.

After you've done all that, see how you go. One thing DO NOT overlook this step, think of a lever or a see-saw, the smallest inconsistency on any of the surfaces can cause some problems. Then make sure you do that Rotor locating nut up nice and tight and then redo the wheel nuts to torque.

If that doesn't fix the problem, take it to the best wheel shop in town, get them to do a full alignment and balancing, front and rear, as well as check for rim damage and flat spots. Obviously make them aware of your problem and that they need to fix it. My tyre shop actually got me some steel shims, that slot over the hub area, and the wheel fits snugly over the top and centers properly, get them to fit some of those, as they will properly center your wheel.

Do all of that, and see how you go.
