Brand new M4 totaled already
I usually got the euro rotors (floating and x drlled), SS lines, ATE 200 Gold
I stuck with oem pads: easy on rotors and good cold bite though dusty
Never got fade even on long downhill runs
The do have a bad rep for track use though, deserved or not
I think a lot of it is the use of single piston sliding vs multi-piston fixed
Without a starting a raging debate floating have their advantages but look cheap or low tech
Not 'cool'
Having said that the AMG ones look much better but the M felt as good, in large part to better wt distribution and the suspensions anti-dive geometry
Cars weigh about the same
M3 is a little faster
M3 e9x
F 360x30
R 350x24
Both are floating and cross drilled
335i
F 348x30
R 336x22
Niether are floating or cross drilled
Those are substantial differences
The Best of Mercedes & AMG
1) Pad / Rotor Compounds
2) Calipers / Swept Area
3) Brake MC / Proportioning Valve
4) ...
it has larger rotors, basically the same material
larger pads and more aggressive on the M3
crossed drilled, better heat dissipation
floating, better heat dissipation
much larger swept area, the fronts alone 15% or so
plus since the caliper is at greater radius (larger disc diameter) more brake torque (T = F x radius)

Yes, on paper BMW will always make sure the M3 wins.

Even with the e46 m3 saw lots of complaints around the brake setup at the track, per what H20 MRV said...
Plus modern cars are designed to crumple. It doesn't look like it was that hard of a hit, but regardless you'll see that the A-pillars and windshield are still intact. Passengers probably opened the doors and stepped out.
I think the new M's are ***. They keep going less is more, trying to convince people that plastic is weight savings. Garbage! and a crappy exhaust note too.
That was a severe impact against an immovable object
And he walked away
$$$ for the car or the hospital/undertaker??? Lol
Old volvos had a system of cables & pullies
Engine to seat belt tensioner in opposition
As the engine was driven back it pulled on the belts
The weight backwards of the engine was used to negate the forward motion of the occupants
Slick
Then airbags came along
