Well, drifting with ebrake while in gear, power slides, anything that makes a sudden change in motion to the drive train. Such as hitting the ebrake while in gear... I suggest you slam the stick forward into neutral and give it at least a couple seconds for it to fully disengage before you hit the ebrake...
Don’t drop it from neutral to any gear, wither it's accidental or not. That’ll really $#&#$ up the transmission, differential, and anything else in-between, much more so in an auto than dropping a clutch in a manual. Many manual clutches have springs to absorb some of the shock of such engagement, (excluding performance clutches and maybe even BMW's, they might not have said springs but it’s still not as bad as doing so in an auto)
Try not to power slide into a curb... or anything for that matter. Your wheels, axles, differential, and tires don't like that.
Get a LSD if you’re going to drift, otherwise doing so might tear up an open diff from all of that torque going to one wheel, plus it will be a lot easier to drift. Best if the car doesn’t shift gears while mid-drift, the transmission wont appreciate it when it shifts, the wheels suddenly gain traction and stop spinning mid-shift, and it fully engages into 2nd or 3rd with power being applied at relatively high RPM’s. Guess what you just "dropped the clutch" again. Be sure your able to force the gear shifts with a manual button or whatever.
Avoid jumps or getting the wheels airborne more than 6 inches, you slam your suspension among other things. Take a look at my sig, that car was royally messed up after they filmed it.
I guess DRIVING it on like a course is fine, although still stressful its much better than hitting the ebrake around corners and all the crazy & stupid crap I do.
I think I reduced the value of my car by about 10,000 after I have driven it for like 7 months...
I want new: engine, transmission, differential, headlights, and shocks. Thats a lot of work and probably less expensive just to by a new friggin M3 or somthing.
