If you feel it the most in the steering wheel, then most of the problem is in the front wheels. If you purchased aftermarket rotors, chances are they are from china and are warped again and need cut or replaced. What you need to do is make sure the caliper slides are free and move easily and the caliper pistons move smoothly.
Let me know what you find.
