Steering wobbling at speed Options

[PaukST]

Ok, so I just replaced my ST's front brake rotors, and now I get some ferocious steering wobble whenever I'm driving 35mph+. They're Beck/Arnley, got them off RockAuto.com. I swapped one of my old rotors back on, and the wobbling lessened dramatically. I took them both to O'reilly's and had them turned, and the guy running the machine said that one of them (not the one I swapped back out for my old rotor) was definitely warped. You could hear it going ksssh---ksssh---ksssh on the machine. So they finished them both, and I just got done reinstalling them and I still have the same wobble as before... It starts wobbling by 35mph, and gets really bad by 60mph. I'm probably going to cut my losses on these and get a new pair from Advance or something. Does anyone have any thoughts on this? I'm already way screwed on this I think, but it would really suck to replace them yet again and find out I still have this wobble.

Oh, and it may be worthwhile to mention that I changed out the old rotors because I got a lot of pulsation in my brake pedal when stopping. I never had noticeable steering wobble with them. I also recently started noticing a vibration around 60mph which would slowly sweep back and forth through the car. I'd feel it vibrate in my feet and it would move its way to my seat, and back.

With the new rotors I don't get pulsation in the pedal when I brake, but now my steering wobbles constantly while driving, the faster I go the worse it gets. I don't know if the aforementioned sweeping vibration is still there, because I rarely take it up to 60 with the amount of wobble I'm getting, and I probably wouldn't be able to notice it anyway. I got an alignment the first day with the new rotors, didn't fix it, and had my tires rotated and balanced the next day, which didn't fix it either.
