If you look at the prelims top 20 times in each class in March and compare to top 20 in April, we see that Unlimited had a perfect shift to faster by better than 0.01 sec across the board. The top 7 in Eliminator did the same. BUT__ only a modest improvement in SPRO, and with the exception of one or two cars, all the best SS had slightly worse times. SO, what are your thoughts on what can make the razor wheels run faster while slowing down the 4 wheelers ( and the magic buried wheel design was not hurt as much)?
