    I had a stock IRS with a billet flow brace and leave at 4500 RPMS on slicks and it has survived many high 10 second runs with 1.60 60's. No wheel hop with the stock bushings and ET Streets or Drags.

    Drag radials well that is a different story. It would hop with those tires.

    The 03-04 IRS shafts are stronger. the 01 shafts are stronger. The stock 99 shaft is not so tuff. Just my two cents worth.
