The stock spring will only last two race days at the max. After that you will find that your car will start to bog coming out of the turns and seem to not really clean itself out until the straight.
If you want the correct spring from the start use the MSR spring. This spring will only last at most about five races. They get heat cycled and loose their spring pressure.
