So you send sharp shocks of force into the drivetrain and suspension bigger than you get from any normal max-throttle driving. It tears stuff up pretty quickly if you don't recognize the problem and ease off the throttle. The rubber bushings in the diff, trans and engine mounts help absorb some of the shock, along with the rubber driveshaft guibo, but it will find any weak points like bolts that weren't torqued properly.

This is not something you see in normal road racing that you could argue an M3 was kinda meant for. It's also not a fast way to get off the line, so you won't see it often in World Challenge or DTM, even though they have to do a hard launch to start each race.
Are there scenarios where spinning the wheels doesn't cause wheel hop? Are guys doing donuts in parking lots tearing up their rear-ends? What about sliding around on a skid-pad?

Not being argumentative, genuinely curious. I did some reading up and saw some youtubes that showed the suspension components during wheel hop and those shocks looked rough. Got me wondering how much damage kids spinning around were doing.
