Axle tramp is the just the cars tires and rear suspension trying to cope with the power you're throwing at it and get traction at the same time. The tires initially spin, then get traction then spin then traction ...it causes a small chain reaction and you get the rear tires basically bouncing up and down fighting for traction. There are ways to overcome this but short of turning your M3 into a drag car , I'd leave it alone and stop spinning the tires
