Curious is there any way to modulate braking progression? It's kind of all or none in the competition trim.

No discernible difference between noncomp vs comp brakes.

If you are talking CCB vs Regular, there definitely is difference.

I'm thinking brake pad may make a difference

Love how much people think the comp is different than a normal M5

I've been saying this for years.

As a comp owner myself, I agree its pretty funny, they're nearly identical cars, with very little bit of difference.

We should do a poll though, because I feel like its shifted a little, its not the comp owners anymore being triggered, its the CS owners being triggered or maybe its just me.

Having driven both, there is a difference in handling. Equally important, there is an aesthetic difference. All of this is accounted for in the price difference, which is justified.

I'd go so far to say, rather than discernible difference, there is literally NO difference in the brakes themselves.

Only carbon, or no carbon. All M5s have identical brakes, steel base vs steel comp, or carbon base vs carbon Comp vs carbon CS.

Now, I suppose one could argue minor (very minor, like maybe inches, if that) differences in stopping distance or performance (highly negligible) due to different weights of the car itself, and if any suspension would change the stopping performance. But the brakes by themselves, identical.

But that argument would be a BIGGG stretch and would likely be pure semantics.

I like the brakes...in the sense that you get a quick and strong reaction when you hit the pedal.
IIRC there is also a brake boost sensor that reacts to a quick change from throttle to brakes and assumes that you are in need of some quick deceleration.

On brake performance...its not going to make any difference to an M5s brake stopping distance (single stop, street driving) whether you have std brakes, carbon ceramics or even F1 brakes. The stopping distance is a function of tyre grip once the ABS is activated.
Assumes CCBs are at working temp, if cold/wet then they may take slightly longer to stop vrs std.

Yes you're 100% correct. Suspension(ride height, camber, and dampers), 17 HP, aesthetic differences(black trim mainly), and several other items. And the price difference reflects the "upgrades." I use " because while most would look at the differences as upgrades, some would look at them as down grades. The comp is stiffer, louder, and a tad different appearance. Some prefer the opposite. These are all subjective wether or not they're better or an "upgrade". I actually find it odd, we call the base m5 a "base". To me that signifies being lower end. Which to me it absolutely isn't. It's the same car, with some differences.

However your thread is referring to comp brakes being all or nothing.... Thats not a comp difference. The brakes are the the same on all m5s. If your comp has carbon ceramic brakes, and the base you drove had steel, that would be a major difference. But the comp itself does not come with carbon brakes, its an option. Just like its an option on the base to get (the same) carbon brakes. But steel for steel or carbon for carbon theyre identical.

Surprised someone finally said it lol, the countless arguments I have with people (not on here) about oh I'm upgrading my breaks so I can stop quicker and my response is, can you get abs with your current brakes? To which the reply is why does that matter? Realistically if you can achieve abs without jabbing the pedal(just adding pressure), your brakes are 100% overpowering your tires, but a lot of people sont seem to get that.

Now you have done it!

OK, I'm going to chime in here - you guys are correct, Carbon (composite) brakes absolutely do not give you any improvement in braking distance (except see *).

At handling limits, the decreased weight at each corner (unsprung mass) WILL assist. We'll not notice this on the road - on the track, and at 9-tenth's, the handling will be improved ever soo slightly...

* On the track, when you're really pushing that brake-pedal, lap after lap, the carbon brakes DO assist with 'heat soak' - saving you from boiling the brake fluid, and thus makes braking response repeatable and, ultimately efficient 👌

You all need to try threshold-braking, where you brake until -just before- the ABS kicks-in, this decreases distances even further than relying on the ABS alone: maybe 10-20% improvement over pure ABS. It does take some practice... if you can feel 'pulsing' of the pedal, but no ABS kicking-in, then you've got it 😊

This is from knowledge gained as a pro driver (I have a race-license), and worked for Porsche. Yes I've turned from the Dark-side to The-Light 👍

Is there a speed at which the M5 on std steel brakes wouldn't be able to maintain ABS activation to a full stop as the heat produced would exceed the brakes thermal capacity (and fade)?
I've tried mine at 100 mph and it activated and held ABS function no problem.
No sure how it would be at 150mph...that would be a lot of energy (heat) to dissipate.

Try it and report back.

100 is nothing. 150 is the better test. The question is how many times in a row would you have to stop from 150 to 0 to trigger a problem. 5?

Over the years, I have read big brake kit tests where typically virtually no stopping distance improvement shows up until after about 10 stops in a row from 100 mph when the same grade pads and fluid are used on the original and BBK.

I sure liked how clean my wheels stay with CCB. (and yes, I ordered them on my 23 as well for the same reason - that, plus how the fill the barrel of the wheel).

That said, I also like the initial bite of the CCBs - granted I never drove an M5 with steel and CCB back to back, my experience is limited to my F80 and my F97. Brakes in the F80 were amazing (lighter car), brakes in the F97 were not so impressive (heavy beast). Brakes in the F90 were pretty amazing to me.

I don't track, I got the CCBs for me - they do perform great, they look great and M compound steel brakes make a TON of dirt (not saying CCBs are dirt free - but sure makes weekend detailing worth it). Expensive for that reason alone? Yes of course but then again spending 100K + on any car isn't exactly a rational financial decision.

I did do 150mph+ once on an autobahn in Germany many years ago...it wasn't an especially enjoyable experience.

Sometimes you have to take one on the chin for the good of the community.

my comment spurred into something way too deep...

I was simply saying the brake feel (not performance metrics) of a ceramic setup vs non ceramic setup is noticable... pedal travel is far less, and the initial bite is harder.

I agree with this and have had both setups (current are ceramics)
