I definitely LOVE the 125!!! I still haven't got a chance to floor the gas yet. I can lost my license anytime with that. It's great fun to drive. The M-Brake really making a HUGE difference in terms of braking power. In terms of actual size difference comparing to the my normal 118 brake, eye measurement, I think the front disc is at least 25% bigger, rear disc is at least 50% bigger. Calliper is like 1/4 of the disc size. In the real world, so far i never need to apply more than 50% of the braking power, and I almost feel like my 125 is jumping up, hahahaha, if you know what I mean. I have already gone through some fun ride. I can guarantee the M-Brake is a HUGE improvement over the normal one. And not to mention is look so much better as well. You gonna love that!

The normal series on my 118 & the Sport Gearbox on my 125. They behave very differently.

If that is the blue M-Brake, they are the same.

So far the M-Brake quite satisfy my need. MUCH stronger braking power than the normal one on my 118.

But all I can say is, this M-Brake is a very very tight fit for my 17" rim. Literally it fills up the entire rim.

Nice looking car mate, and I love those brakes! They look really nice. I reckon it would look more sexier if you had opted the bi-xenons. IMO those bi-xenons should be a bloody factory standard in every BMW!!
Enjoy your new car, and try not to lose your license.. :P |

btw, this is way too easy to lose my license on this 125. Really fast. Can iron out all corner to straight flat. The engine just scream out "push me harder!" anyway, still haven't got a chance to floor the gas yet. Especially with the extra unmarked cops in Canberra ACT.

I think the brakes (M-Sport vs Performance) are the same, except for the color. The reason M-Sport brakes are so much cheaper, is that they come with the car. If you want to fit them after the car is delivered, they are also very expensive.

If that is the case, I am even more happier!! Coz I am pretty sure the M-Brake is HUGE, much bigger than the normal. Stopping power is dramatically improved as well! The difference is too obvious. Worth every pennies for the upgrade.

Sorry to burst the bubble a little here, I am informed that the diameter of the disc is the same on the front, slightly larger than the M Sports on the rear and the pistons are larger in the BMW performance units.
They are Inner-vented, lighter weight discs for more extreme driving and higher thermal factors. They are Four-piston aluminium caliper on the front axle, two-piston aluminium caliper on the rear axle. Available in M Performance Red, M Performance Yellow or M Performance Orange. Includes coloured M logo. |

I looked up the brake sizes.
Stock size on a 116i M-Sport with regular brakes: Front: 284x22 mm, Rear: 290x11 mm. Ventilated discs front, single piston calipers. Optional M-Sport brakes for 116i: Front: 340x30 mm, Rear: 345x24 mm Ventilated discs front and rear, 4 pistons front, dual piston rear. On the M135i, these M-Sport brakes are not optional. If you order M-Sport brakes for a 116i, you get the same brakes as the M135i. Do you have any specs for the Performance brakes? I saw them next to the M-Sport brakes one time, and it was difficult to spot differences, except for the color. Also the parts lists show both ventilated and solid rear discs for the 116i in the regular size. I don't know how BMW decides which ones to deliver with the cars. Maybe ventilated with the M-Sport package? I will have to check what mine has one day. |

AusF20, I am not sure who gave you that information, but I am 110% sure it is wrong information. I just double check the standard one on my 118 and M Brake on 125 (sitting side by side). They are much bigger on the M version. For the standard 118, there is a BIG gaps between the disc & rim, but the M version is filling up the entire rim for a 17" rim. It's too dark now, but I will try to get some photo tomorrow for comparison.

I was referring to the difference between the M Sport brakes and BMW M Performance brakes.
I also have ordered M Sport brakes (blue) for mine, as I do not think for road use the M Performance ones would provide any real advantage. If I was going to do a lot of track work I may have considered the M Performance, though I think I would have then gone for Brembo instead. If you look at the BMW performance cat I posted the link for, you will see the performance brakes are vented, drilled and slotted and the caliper is slightly larger and a different design to the blue units. |

The ETK is listing the M-Sport brake rotors as drilled, vented and slotted as well. On the two sets I was comparing, they looked very similar. |

Here I found two pictures showing the performance calipers and the M-Sport caliper. They look identical to me. The rotors are different, though.

The consensus amongst the f30 guys is that they (MPP and M) are the same, except for the option of having slottted/drilled rotors on MPP..

My dealer's technician says that the M Sport (vented / non drilled) are different to M performance rotors.
They are the same diameter, but the MP are made of a different alloy (vented, drilled , slotted) and the calipers have different pistons and seals. I gather they are more designed for track days for boy racers. That explains the difference in price. I am sure that you will be able to get after market (vented, drilled , slotted) rotors for the M Brakes if you want that Performance look. |

Does anybody have any link to technical info about these calipers, other than comments from sellers?
And what is the price difference? (Retrofit, not delivered with the car, which is A LOT cheaper). |
