    Drag Radials will get rid of a bunch on the street.

    At tire like ET Streets or Slicks with a flexible sidewall will eliminate hop at the track

    I have the stockers back on and have a pile of low 11 and high 10 second timeslips.

    Wheel hop kills the shafts.

    The stockers have held up with the slicks? Have you or are you going solid?
