To be fair, the issue became noticeable when I upgraded to the LG Z28 20x10F, 20x11R wheels. I think the weight of the wheels and tires may be "stretching" the suspension a bit. I just bought a bumpsteer correction kit today that replaces the front/outer tie rod.
I'm getting deflection under hard acceleration and braking. The car also tends to tramline quite a bit on uneven roads. Tires are 275F and 315R.
The size and weight of the wheels will effect the suspension a bit but it shouldn't be as noticeable as you are saying. Have you gotten under the car and inspected everything to make sure nothing is loose or looks out of place.
With the new wheels/tires that have the bigger contact patch I am not surprised that you are noticing it tramline a bit more than it previously was with the factory wheels/tires.
