Redneck math is for every 3lbs of rotational weight saved, thats 1 extra wheel HP. So let's say that the 53.5 is split among all 4 wheel perfectly (definitely not the case), that's 13.375 lbs per wheel. The 2 rear wheels are the only ones driving the car, so you're looking at a (VERY VERY ROUGH) 4.5 whp per rear wheel, or 9 whp total difference with the CCB's vs the steels. Now obviously this is crude math, but somewhat gets the point across. The CCB's are only part of the equation too, the CS wheels will be a whole lot lighter than the piggy 788 wheels, which will also help tremendously.
