Summer wheels back on + new brakes = vibration and bump steer

I've put my 18" Hamanns with Nexen tires back on over the weekend. I've also replaced my front brakes with cross drilled rotors and Axxix Ultimate Ceramic pads from r1concepts. I've bedded the brakes correctly. Also, since my tires are directional, I could not rotate them so I just put swapped the fronts and the rears.
The OEM sway bar end links appeared to be leaking - I think they may be incorrect length since my car is lowered. I've installed new Meyle HD FCABs last summer and got an alignment done at that time as well. The car appeared to pull to the left slightly when braking so I assumed it was the brakes.
Right now, when braking over uneven surfaces, there is a slight vibration in the steering wheel (not the pedal) and the wheel will jerk to the right a bit over bumps. It might jerk to the left as well, but I have not driven it that much so I am not too sure.
Any ideas? Should I swap the wheels back? My tie rod ends are still the stock ones, could they, coupled with sway bar end links be causing this?
