With some rotors, that's also a good way to get them warped and out-of-round....sudden applications at high speed causing a lot of heat buildup very quickly, in a couple of seconds. That can mean either new rotors or a trip to the brake shop to get them turned, if there is enough metal left on them to do that safely.
That applies to steel rotors, of course.....ceramic rotors can usually take much more abuse without warping.

Normal cars you only need to do 3 60-30s at moderate/light then 3 40-5 hard braking followed by a nice cool off.
My X5 has developed a small oil leak, so I brought it to my mechanics shop last week, and much like I suspected it is the upper oil pan gasket. He's going to be fixing it, I have no idea what it's going to cost, but I found a video of what it takes to get it done.

Cool, they look great. I imagine replacing pads eventually but the rotors I'm sure are good for many, many thousands of miles.

Yeah, not gonna be cheap as you already know.
Most of the cost will be probably be labor.
Looks like he pulled the power steering rack and engine cradle to get clearance and move all suspension components out of the way. Yikes!
I'd get a new OEM oil pump while he's in there with all new O-rings like in the video.
Didn't know BMW's run a chain driven oil pump.

Ceramic rotors have their own problems. They are extremely expensive, they can chip or ever crack, and they get damaged by all the reagents sprayed on the roads during the winter. They are really mostly made for race tracks, they are not practical for street cars.

High end steel brakes can take a lot of abuse, the brakes the LSs come with are considered a high performance option on something like a Mustang or Scat pack that requires you to pay more or get one of the high trims. Lexus always provided the flagship with opposed multi piston fixed calipers and very heavy/durable vented rotors.

^^^^Yes, I'll agree with the race-track statement. Though I could be wrong in my memory, the first ones I can recall on street-legal cars were on the Porsche GT2 and GT3, which are often driven on tracks as well as the street.

It's an expensive option on any car, and unless the car is taken to a track for high endurance racing where it brakes hard many times in a row, regular steel brakes will fare better due to concerns I listed before. Most people just get them for bragging rights.

The perfect solution IMO is Porsche Surface Coated Brakes (PSCB), which are a much smaller upcharge when new, and have a similar longevity/low dust properties with their PCCBs (The calipers are painted white to underscore this point), but are comprised of tungsten-carbide-coated iron rotors and specially-formulated pads to achieve those results. They don't have the insane heat capacity or lightness that CCBs do, but they're not brittle and absurdly expensive either. If I bought a car that had these as an option, it would 100% be the first box I checked.
