M Compound Brakes - 380 x 36mm (front) / 370 x 24mm (rear)
M Carbon-Ceramic Brakes - 400 x 38mm (front) / 380 x 28mm (rear)

What's with all these cars in individual colors ? They had a Mexico blue m4 in the last video, now an m3 in some kind of orange and a bright green m4?

How come we can't order them but clearly it's possible? And half the decent colors (frozen gray black orange etc) aren't even available in the USA but are available everywhere else.

I'm guessing it's Signal Green

The front pads indeed are large, which will help with managing brake pad temperatures

I still don't like the rear sliding caliper, but most of the braking is done with the front axle. Hopefully the rear is up to par and can brake well.

Back in the E9X days, the sliding calipers it used held up to track use better than its contemporary competitors like the RS4 and the C63. There is more to brake performance than fixed vs sliding calipers.

So single piston floating caliper on the rear axle to reduce weight and to allow for deeply concave rims...

[BwoodBMW]

that rear caliper is comedic looking

[Jason60051]

That rear caliper has to go...

Interesting how the rear brakes are for financial reasons rather then for performance. Sure front does 60% to 80% braking, but you can go w an optional helper caliber to use as a parking brake. See Ferrari. etc..

[Bumpinjeep]

So the front brakes are the size of the rear brakes on a M2 Competition and the rear brakes are almost nonexistent?
The optional brakes are the same size as a M2C but are ceramic? So bizarre.
I wonder if you can replace the standard M2C brakes with the optional G8X ceramics and they would bolt right in?
Are the ceramics off of the M2CS the same size?

[GOLFFRR]

signal green? that such a great color!

[nicksm3]

Of coarse the front now has a 6 piston setup because the CARS ARE HEAVIER!
Also that rear single piston has me scratching my head..
now the cars are heavier than before, 6 piston front and single rear, in my world that's brake bias issue waiting to happen while on a circuit.

The sliding rear caliper is all about cost savings and easy integration with the electric emergency brake. That's why even the ceramic brakes have a sliding caliper in the rear.

There are not typically weight savings for sliding caliper even though it is less pistons. Often times, the sliding caliper is heavier than the similarly sized fixed caliper.

I do find it interesting as to how many German makers are going to this hybrid fixed front / sliding rear set up. For example, the MB GTR has similar set up. My assumption is again in regards to the electric e-brake.

[PLF69]

I bet 99% of the ppl complaining about the rear brakes is purely for cosmetic reasons and will never exploit the braking capacities of the car on a track. (I have AP racing bbk all around on my M2)

I am just super happy that the pad is bigger on the front and that they integrated cooling ducts. Of course the older rear caliper looked better but I won't feel bad about it and even less while looking at my friend's AMG GTS

[Boostedphil698]

The rear brakes are a joke for the price of the car.

[Peterglen]

All this cost cutting on the most expensive M3/4 ever... I’m glad the Pcar finally got me this time.

[jmg]

All this talk about weight savings and all they had to do was resist the trend to annoyingly make every car bigger than the last. Stop making cars bigger. If I wanted a bigger car I would get a 5 series.

Where's the part where BMW tells us to pound sand if the brakes squeal?

[SYT_Shadow]

I love all the pitchforks when BMW puts a sliding rear caliper on the M3. That the AMG GTR Pro has a sliding rear caliper as well seems to go right over most people's heads. And it costs several multiples of the M3

Also, for the ones who are so aghast at the M3 having a sliding rear caliper that they are 'moving to Porsche'... are people on such heavy drugs that they feel the M3 for 70k is unacceptable but their 4 cylinder Cayman S is somehow better? Or are they buying a car that's 2x the cost of the M3 and surprised it has advantages?

For the street or 'mountain road' use the sliding rear caliper will make zero difference. For heavy track users, such as myself, no OEM brake system would ever pass muster so it's all getting replaced regardless. Apparently even God's own vehicle, the perfect mix of angels, strippers, unicorn blood and fairy dust 991 GT3RS, also ends up with the same aftermarket brakes an M3 guy puts on when heavily tracked.

It's the same price as every m3 accounting for inflation.

The AMG GTR also shouldn't have a single floater and along with the M5.

I don't like it either mind you, but apparently it meets the engineering targets of a $200k GTR Pro, so I'm not too worried
