RWD auto burnouts
Discussion
Im sure plenty of folk here have seen super muscle cars on discovery. Anyway he always does a huge burnout on a brand new crate engine - break em in hard.
The tactic I understand is to put it in drive handbrake off foot on footbrake then floor the throttle. The torque will make the rear wheels spin with the brakes on fully.
This looks stunning mega burnouts until you can barely see the car and ten you ease off the brakes while keeping the throttle wide open and spin further as you go along
Question is isn't tree a big risk of tempering the discs? Couldn't you ruin a set of pads and discs very quickly? And if so on that American show he always does mega burnouts does he then change discs and pads or.. Assume tempered discs are acceptable for future owners

If you have a line lock fitted you isolate the rear brakes so no rear braking
Otherwise you the discs ca get overheated
But say I went to McDobalds in my normal production BMW and wanted to burn out isn't how I described it the only way?Otherwise you the discs ca get overheated
Also for those f you who go to car meets do auto drivers ever burn out?

That would be the way to do it. Either that or put the car hard up against a building. Also for those f you who go to car meets do auto drivers ever burn out?

Lol up against a building brillient. Is it also important to select first gear and hold it at full revs rather than D or DS? Or is 2nd gear held at full throttle ok - just thinking the exit would be superior if in 3"2nd good for 60mph than mid 20's for 1st.
Last car I did it with had rear drum brakes that were easily overcome, they still wore out though. I remember being stopped at a set on lights during winter with my foot on the brake and the rear wheels continued to spin on the ice just with tickover power. 
If you are having trouble getting them started because the rear brakes are too powerful, just ease pressure on the brake pedal for a fraction of a second, enough to get slight forward movement, then reapply the brake. That momentary pulse is usually enough to break the rears loose.

Just leave it in D, the box will change up as usual when it wants to. I have seen a stationary 120MPH+ when doing a particularly savage burnout. In my defence I was a reckless teenager at the time in a £500 banger.

Brillient. That's what in talking about. He tempered those discs for sure - is there a risk he would melt/damage the alloy wheel too if it's gets too hot?
I imagine he would pop a tyre before it got to alloy melting point.
Just re-reading that it's a BMW, you do know to switch off the DSC fully (long press of button) before trying don't you?.
Also don't worry if the ABS light stays on after, it will go out after you have driven a while and the wheel speed sensors/ECU re-calibrate themselves. I was in a bit of a panic after putting my car on a rolling road and thinking I had stuffed something up with the ABS ECU or something else spendy.
