A BBK upgrade on an M car for street use is a waste of money IMO.

There's good reasons why Brembo is principal supplier for some F1 teams - quality (and track diff from road use).

If you want to see how well the stock brakes perform do an exercise from about 90-100mph braking very hard and you might change your "number of pistons" influenced opinion. The main advantage is, as BMW-M-Mexico stated, the unsprung mass reduction. Oh, and you can't mess with the look.

...My opinion about the stock brakes has been solidified after attending the BMW ///M Performance school.

They are amazing for stock on the track. Does that mean they are perfect, no way.

My M School day of driving hard at 100-110 mph stuff they were excellent.

As the speeds increase they will prob get weaker but even for light track use they are great.

Better to make the car go faster and improve handling.

Just FYI, the weight reduction is fairly trivial. 7 pounds overall. The new Stoptech Trophy series might shave off about another 10 pounds.

Performance Friction makes exceptional pads for OE and most BBK. They have several compounds to choose from.

PF might not be a big name in BBKs, but they have a hell of a pad selection.

Hawk also makes a decent pad for our cars.

I would say if you are real committed to producing really quick times then your OEM brakes and pads will last no more than about 3~4 laps tops, or about 15mins continued abuse.

Try the same thing in a Porsche and you will find them lasting at least 2 and 1/2 times longer, plus left to cool down and they will recover quicker. It's one area where I feel Porsche led to way among OEM equipment.

LOL... next time you quote me you should quote my whole sentence. Here let me post it for you

If you wanted a performance upgrade I'd start with braided brake lines, competition brake fluid and better pads. Won't have all the "bling" of the BBK, but will give you better-than-stock performance at a reasonable cost.


OMG +1 on that !

Unless you're tracking your car every weekend Brembos are a waste of money and if you read most forums changing what quackbury mentioned is MORE than adequate for 99.9% of all M3 owners !

track pads , fluid + lines will do everything you need unless you want the bling bling of the Brembo calipers or actually do RACE every weekend.

Now if you READ my whole sentence you will notice that I say that MOST M3 owners will NEVER need the brembos and can get away with "track pads, fluid and lines" . If you're 1 of the FEW that would benefit from the 7k brembos then good for you but I stick by the fact that for MOST they are a waste of money . If you have it to spend then good for you but if its between 7k brembos OR for the same price : AAX-Pipe, AA Exhaust, ECU tune, Pulley , Filter and OMG Bank breaking $200 scoops... I would chose B and just upgrade my pads/fluid/lines.

Always focus on the ENTIRE sentence next time. (If you can afford both then DOUBLY good for you btw)

I don't think ANYONE is questioning that the Brembos are better but if you only have 7 to 8k to spend ... read my post above. If moneys not an object then don't stop at the Brembos keep going to the superchargers/strokers as well.

OEM brakes with racing pads and SRF fluid are more than enough for pretty brutal track duty. Pcars come with better fluids and pads out of the box. The reason BMW does not do the same is because of all the pansies complaining about noisy brakes. There are more folks in this forum complaining about noise than those posting in this thread. When that changes, BMW may grow the balls to give us a track worthy OEM setup. If it were me, I'd sink the 7K into motons.

Can't agree that noise is or even should be a problem, I have owned 4 P-cars and none suffered noisy brakes. BMW's basic design on their M car brakes are as much to blame as the lack of decent pads and fluid.

BTW I am not saying that changing pads and fluid wouldn't improve the durability of the brake system, it's just that this is at best a short term solution for someone who isn't that serious about tracking their car, if they were then a complete change is the only fix.

I (at night no traffic) did some tests a few months ago. From est.150mph braking to zero. Great.fwiw.
Accellerating again after that and braking from 100-120mph to zero. Still rather alright.

The third time the brakes needed to get some rest.

I was going to include that Autobahn driving at excessive speeds could also cause problems but felt someone with more experience of this would probably chime in.

Thanks for the info.

P.S.

I would like to add that the S5 brakes weren't great either and the only Audi I felt to have decent brakes was the R8.

I have 376 mm AP RACING front, and they work incredibly great!

You can track it and push hard for 30/40 minutes without any loss of performance!!

And when you push really hard, tyres can't go with, you neef toyo R888 or MPSC to use the AP correctly!

If you don't track, it's totally useless, oem with good dot and pads are very very efficient for daily driving, even if you break hard!

Nice to see someone post with actual track use with stock brakes and just changing pads/fluids.
