No son los mismos, de hecho cuestan mas de 2000€ si no recuerdo mal,
Técnicamente son iguales, los m sport que los m performance. La diferencia está en que lleva los discos ranurados y perforados y que los delanteros son de 370mm que creo que los F3x ya es así con los M sport.
No son los mismos, llevan 6 pistones delante en vez de 4 y más cosas

Yo no se si son los mismos o no pero no tendria sentido que lo fueran ya que unos son un extra de unos 700€ y los otros un recambio de unos 2.700 más la mano de obra, lo cual le daría un precio final superior a los 3000€ y repito, son un recambio, no un extra, pero bueno, tratándose de BMW no me extrañaría nada que sí lo fueran y si más de uno lo decis... supongo que ya lo habréis mirado.
Por otra parte, además de la diferencia de precio, a simple vista no parecen iguales, no ya sólo en el color sino en la forma, las rojas parecen más alargadas y grandes que las otras, o igual es el efecto de la foto, el color... no se, yo las veo bastante diferentes, y en el caso de los discos, como bien dices, sí que son claramente diferentes, no ya sólo perforados sino que también parecen mayores.
Como digo anteriormente sólo son mis impresiones, ni lo he mirado (no sabría donde hacerlo tampoco), ni lo he preguntado en el concesionario, ni he tenido ninguno de los dos ni nada así que fácilmente puedo estar equivocado.
Son exactamente los mismos en cuanto a diámetro de los rotores y pinzas, cambian las pastillas y los rotores perforados, aunque
son perfectamente intercambiables entre ellos.
No sé de dónde sacan que tienen 6 pistones... :rolleyes: Las que tienen 6 pistones son las pinzas delanteras de los frenos carbonocerámicos...
Aquí viene una excelente comparación entre los de serie, M Sport y M Performance, con ilustraciones...

1. My car has grey calipers.
(click to expand)
Grey (unfinished) calipers are the stock part used around the world. However, in the US, it could also mean it came equipped with one of the M Sport Brakes options (see below). Following the logic in the BMW parts program, there are multiple M Sport brakes for US cars. It's not obvious which brakes BMW installed on your car. The option code remained the same (S2NHA) but there are two different sets of part numbers related to that code. You definitely want to be clear on which brakes you have because rotors of different sizes are not interchangeable. One dead giveaway is from the rear caliper - a single piston caliper is for the stock 335i brake sizes; a 2-piston Brembo caliper is for the larger brakes.
US M Sport trim package (P337A): The M Sport is one of the trim packages offered when the car is ordered (base, Luxury, Modern, Sport, or M Sport). It was around $3,000 and got you 18" wheels, M steering wheel, M Sport aerodynamic kit, Sport instrument cluster, and glossy Shadowline black exterior trim. The brakes are mostly the same as the other trim lines except for the front pads. The front pads were actually the same as used on the M Performance accessory kit. Many drivers complain that they lack feel and initial bite. Luckily all of the F30 335 calipers share the same pad shape so pads can be interchanged. The rotors and rear brakes are all the same as a standard 335i/435i.
US M Sport Brake Upgrade 1 (S2NHA) (pads only): In the BMW parts database are pads listed as "M Sport S2NHA" that fit the stock 4 piston front calipers and the
single-piston rear calipers. These also happen to be the stock base pads used in Europe. This was a $350-400 option on 2012-2013 cars and could be added to ANY trim package (even a base model). The Euro pads have much more bite and dust a lot more than the stock pads. The bite makes the brakes feel stronger but the dust can be excessive for some people. The rotors are blank - no drilling, dimpling, or slotting.
Specs:- Front: Brembo 4-piston calipers, grey/unfinished; 340mm blank brake rotors
- Rear: OEM (Bosch, Ate, etc) 1-piston calipers, grey/unfinished; 330mm blank brake rotors
M Sport Brake Upgrade 2 (S2NH/S2NHA) (pads, calipers, rotors):Sometime during 2012-2013 production BMW changed the M Sport Brake option to include larger front and rear rotors, a different front caliper (still 4-piston Brembo), and 2-piston Brembo rear calipers. It was a $650 option but still called "M Sport S2NHA" and could be added to ANY trim package (even a base model). This kit was the same as the M Sport offered in Canada/Europe. The calipers should be blue with an ///M logo but there's a slim chance they could be grey/unfinished with no logo. The front pads were a similar aggressive Euro-spec pad as above. The rotors are blank but the dimpled/slotted rotors from the M Performance brake kits are a direct fit if you want to change their appearance.
Specs:- Front: Brembo 4-piston calipers, grey or blue; 370mm blank brake rotors
- Rear: Brembo 2-piston calipers, grey or blue; 345mm blank brake rotors
2. My car has blue calipers.
(click to expand)
In Canada and Europe, the M Sport brake option (option code 2NH) came with blue Brembo calipers in the front and rear and larger rotors. This kit has the same specs as the M Performance accessory kit but with the blank rotor design and blue calipers instead of red, orange, or yellow. Officially the US did not get the blue calipers in our M Sport upgrade until the 2014 model year. All 2014 models (including F32 Coupe and F22 2-series) with the M Sport Brakes Upgrade (still called S2NHA and $650) used the same components as the rest of the world. These are the same brakes as what was standard on the M235i/iX.
Specs:- Front: Brembo 4-piston calipers, painted blue with an ///M logo; 370mm blank brake rotors
- Rear: Brembo 2-piston calipers, painted blue with an ///M logo; 345mm blank brake rotors
Since the M Sport shares the same specs as the M Performance, the parts are interchangeable. You can add M Performance dimpled/slotted rotors to an M Sport car and they will be a direct fit. They are also a little lighter than the standard blank design. Pads are also interchangeable among the calipers. The M Sport pads are more aggressive and give more bite and feel than the M Performance pads.
3. My car has red, yellow-gold, or orange calipers.
(click to expand)
This is the M Performance accessory brake upgrade. It was offered through the BMW dealer as an accessory retrofit and would have been installed by the BMW dealer or purchased from another parts supplier such as Turner Motorsport. From 2014-on they could have been installed at the port of entry. The calipers were red, orange, or yellow-gold but they were the same Brembo calipers offered on the M Sport Upgrade above. The rotors were also the same sizes as the M Sport and had a dimple/slot design on them. They were also a 2-piece design with an aluminum hat that saved a little bit of weight.
Specs:- Front: Brembo 4-piston calipers, painted red, yellow-gold, or orange with ///M logo; 370mm dimpled/slotted brake rotors
- Rear: Brembo 2-piston calipers, painted red, yellow-gold, or orange with ///M logo; 345mm dimpled/slotted brake rotors
The M Performance brakes sold for a large premium over the stock or M Sport brakes ($2,000 or more plus installation). Yet the rotor sizes are the same as on the M Sport. You did get a sporty looking rotor though. If you have the M Sport brakes you can add the M Performance rotors without modification. If you're unhappy with the feel and performance of the M Performance brakes, try using the pads from the M Sport package (see below).

If in doubt just call or e-mail us with your VIN and we can look up what the car was originally built with.
PadsFor the front caliper, the brake pads are all the same. Even though BMW has different part numbers for the pads and for the calipers, the pads are all the same shape and size. Only the compound changes between part numbers. This is unusual because most big brake kits will use a different pad. But with the F30 calipers the pad remained the same. See the photos below for comparisons. Here is the pad breakdown along with some notes on the differences:
PackagePart NumberNotes
US stock/base34106859067performs with low bite and low brake dust levels
M Sport
Euro stock/base
34116865460
(34116859282)lots of initial bite but also lots of dust; performance drivers will like this pad a lot but daily drivers will probably dislike the amount of dust from them; if you were unhappy with the brake feel in your stock setup you can swap the M Sport pads in for an immediate improvement.
M Performance Kit
34116859066low dust and low feel; a lot of M Performance customers have been put off by the pads that came with this kit - they're dull feeling and totally out of character with what they expected. In this case we recommend using the M Sport pads with more bite.
Centric Semi-Metallic104.16090a street pad with good initial bite and feel but with very low levels of brake dust
StopTech Street Performance
309.16090a sport pad designed for aggressive street use. These are similar to the M Sport/Euro pads where they have a lot of bite and a very high temperature rating but need a little bit of heat from aggressive driving to work best.
Pagid race pads
U4931race pads are super aggressive and produce more braking torque than what a typical street pad is designed to create. They are also engineered to withstand the heat in a racing environment. Special materials are used to ensure the pads won't fade or come apart at the extreme temperatures found on a racetrack (over 1,000 degrees F). Race pads like the Pagid Yellow shown below will give phenomenal braking performance but because of the specialized materials they should be avoided for street use.
How did BMW use the same pad for a larger brake rotor? Yes, the overall rotor diameter is larger on the M Sport and M Performance packages. But look closely and you'll see the swept area of the rotor (the section that the pad actually touches) is the same. The 30mm of additional size comes from expanding the center hub. There is more material on the brake rotor hat which gives it the additional diameter.
The F80 M3/F82 M4 use the same pad shape as the M Sport/M Performance brakes.
Front Pad Comparison (showing all 335 front pads are the same shape)
For the rear caliper, things are a bit more traditional. The standard brakes are the single-piston sliding caliper that we're all used to. The M Sport kit used 2-piston Brembo calipers in all markets (grey for US; blue for Canada/Europe). The pads are different between single piston and 2-piston. Pad breakdown to match the fronts above:

Rear Pad Comparison (showing the differences between the single piston and 2-piston pad shapes)
RotorsFor the 335i there are just two front rotor sizes - 340 or 370mm. The 340mm is the standard 335/435 disc size and also used in the US M Sport upgrade option for 2012-2013. The 328/428 also used this rotor in its own S2NHA M Sport brake upgrade and was offered with a dimpled/slotted face. This can be used on the 335/435 stock brakes for an appearance upgrade. The 370mm rotor was used on the M Performance accessory kit and in the later M Sport upgrade option.
All M Sport brakes (US or Canada/Euro) used a blank rotor design - no slotting, drilling, or dimpling. The M Performance slotted/dimpled rotors are a direct replacement for the 370mm M Sport brakes.

Information is inconsistent on how the S2NHA can be ordered. It doesn't appear in either the 2012 or 2013 official ordering guides but show up in BMW ETK, Real OEM, and owner's forums. In the official 2014 ordering guide S2NHA requires 2PE and 0ZMM/P337A. In the 2015 ordering guide, they relaxed the requirements to only bigger wheels with performance tires and top speed increased. So in theory, you could have a base model 335i with no other options except for the upgraded brakes, wheels/tires, and increased top speed."
para nada! (bueno, alguna vez a muy, muy baja velocidad y apretando muy poco el pedal si he oído algún chillidito) Eso si, las pastillas son super polvorientas (las llantas no duran limpias ni un día 
)
