Brembo Brakes vs Upgraded OEM Brakes

[L1FHR]

So I think my E92 2013 M3 CZP have the upgraded brake caliper.
Some people told me that it’s a good enough brakes for the regular street use not race!!
Should I get those Brembo and spend 4Kish or just keep it the way it is.
What’s the advantages for having Brembo brakes?
Any suggestions is appreciated.

Are your brakes fading? If so what pads and fluid are you using?

[GotV8?]

I went with the alternative and upgraded to Hawk Pads to reduce dust and steel braided lines (All 6) and flush your brake fluid as needed, however, if you plan to track your M then the Brembo kit are definitely worth the upgrade and investment and looks very Nice!!!

No such thing as an oem upgraded caliper. What is your goal with the car?

[wyatth]

If you have to ask, stock brakes are probably sufficient for you. That doesn’t mean the Brembos won’t look prettier or feel better, but whether that’s worth $4K+ to you is your decision.

bbk doesn't increase braking power, you're just able to withstand constant hard braking.

[Whit45]

All a BBK will do is give you consistency which will inspire confidence. You'll be able to go as deep into a turn on the 1st lap as you will the last.

Wrong to all contrary. BBK does provide more braking torque by using a larger rotor diameter and larger brake pad surface. Also the design provides consistent braking by allowing to disperse heat better.

To OP none of the e9x m3 platform (except GTS and CS which came with Brembo from factory) offer upgraded caliper.

Unless you track your car regularly a bbk is just for looks.

While this is technically true, the piston diameters are also one of the key factors that go into determining how much torque a braking system can provide. From my understanding, most BBK kits, despite larger pads and rotors, will retain close to factory levels of torque to keep systems like ABS and DSC functioning properly.

As others have mentioned, the primary advantage is the fade resistance you gain. Larger, better ventilated rotors, and larger pad surface areas all aid in keeping the heat down and disperse it better.

I would have to try and find it again, but somewhere, someone (I believe on these forums) did a calculation comparing the stock front braking setup to that of a BBK (believe it was either a Trophy kit or PFC). The stock setup actually has the capability to deliver MORE peak torque then the BBK. I was skeptical at first when reading it, but the math doesn't lie..

BBKs provide better feel, better modulation, better pad life, better rotor life, better caliper life, better heat dissipation, better heat capacity, and good ones reduce your unsprung and rotating mass.

The BBK is easily one of my modifications I've done to my car. It's only better, across the board. The price ($) is somewhere high, but it's also one of the only mods you can do that only improves the car, without tradeoff.

But, you can't realize most of the benefits of the BBK on the street.

More peak braking torque is not "better". Once you can lock up the tires, more torque does not serve a function. I have yet to experience a BBK where you can't lock the tires/engage ABS.

All good, and for the most part, correct points. However, me stating a few interesting bits of information is in no way me being an advocate for stock brakes over a BBK and dismissing the advantages a BBK provides.. The comment regarding the peak torque was in response to the previous comment, I never stated it was actually a benefit - I simply found it interesting as most people would probably think it's the other way around.

I have lots of experience with a full PFC kit on our race car and the performance it delivered, in all aspects, was incredible. Zero fade - ever, unbelievably consistent, and long consumable life span.

With that being said however, the stock braking system on the E9X M3 platform is very capable. With relatively a small amount of mods; braided lines, brass guides, race pads, proper ducting and if you wanted, an upgraded rotor and titanium backing plates - the performance on track is very good. The Grand-AM GS cars ran basically this setup and other then shorter consumable life, the system performed nearly as good as a BBK system would. The stock setup on these cars is much much better compared to the E46's. Again, I'm not dismissing the benefits of a BBK by any means, but the amount of people on this forum that insist the stock brakes on the E9X can't be made to work well for track use is absolutely absurd.

Sounds like you're not tracking the car, and even if you are, try tracking with stock brakes + upgraded pads and brake fluid first.

For street use, the stock brakes a perfectly fine.

[wyatth]

Are these the same as the 6 pot M3/4 brakes?

Not a bad deal given that it includes 4 decent rotors. Curious if someone knows or could calculate brake bias.

[Dave07997S]

To be frank until you move on to dedicated track rubber, upgraded OEM brakes will probably suffice. The nice thing about OEM rotors is that they are easily replaced and quite cheap now if you buy the non BMW branded OEM rotors (Zimmerman).
