I've been noticing some steering wheel shimmy with the skinnies on the front but I figured they just needed balanced so I didn't think anything of it. But I just put the stock wheels back on and hello major wobble and shimmy. I hung my head out the window and I can visually see the tire going in and out 1/2'' or so. Now I consider myself a fairly decent mechanic but I can't figure this out. New wheel hubs, tried two different sets of wheels, everything tightened evenly and correctly. Now what can cause this!?! To make it worse, both front wheels are wobbling. Took a dial indicator to the rotors and they are slightly uneven but not enough to cause this kind of visual movement.
