He said he takes the cloverleaf on/off ramps at "125 mph" (200 km/h). He said if you take out 600 lbs. from your car "you'll be surprised at how much faster it can go".

He knocked 600lbs out of a TT? That's actually really impressive, although that would take the car from a published 3362lbs (TT quattro 1.8T) to 2762, which still is not very light when compared to prepped cars.

I buy my cars to drive them. I also maintain them in accordance with how they're driven. If you haven't encountered such problems on track in your M3, then you're not driving fast enough. This was all done with far less hp than a G37.

I've completely destroyed several sets of pads and tons of tires on with my M3. I've never once cracked a single rotor though. Not once in my entire life.

I can not crack rotors by swapping the rotors out early, usually.

Cracking 3 in one day was totally unexpected, however. To be fair, that track is the hardest on brakes of the tracks I run at. I still need to install my brake ducts.

Braking zones are from 130 > 40, 85 > 40, 105 > 40, 110 > 40 per lap; basically its a bunch of drag strips connected by (mostly) 90 degree turns.

"medium" heat cycles will do this to your rotor

The heat cycles I was putting the rotors through were just too extreme. It didn't help that it was windy and cold. One of the rotors popped in the pits while I was cooling down after a ride-along.



Where did the OP go?

Also taking a clover leaf at 125 mph is more about lateral grip than how light the car is.

They're directly related... more weight requires more lateral grip to sustain the same rate in change in direction. It's just usually easier to increase grip, than to lose weight.

I need to go on a diet.
