    Install NEW brake rotors, be sure no rust or other objects between NEW rotors and hub! Torque wheels to specs. and in proper sequence.

    ok if the rotors turned propely with no defects like heat spots or anything whats your opinion on the abs sensor in the hub itself causing a grabbing feeling as if it isusing abs when it shouldnt be being the vibration? its possible a sensor issue could cause this issue?

    No! ----I think you still have excessive rotor run out or trash behind rotor and hub! New rotors are fairly cheap. Lug nut torque and sequence are very important also. ABS light on?

    Have ABS system scanned to see if any codes are present. You should be able to tell if it is warped disc brake rotors or ABS activation as there is a very distinct difference!! Sensor will not cause the same effect. If all else fails, let a mechanic drive your car. I can't!!
    Good luck with it.
