BMW Brake Rotors & Discs

This is a pair of FRONT 330mm rotors that fit the F30 328i/iX and F32 428i/iX with the optional M Sport trim package (option code P337A) but not the optional M Sport brake upgrade (option code S2NHA).

The M Sport trim package included the M Sport aero kit (front bumper), a sport steering wheel, and other trim pieces that made it different than a regular Sport package. It also included slightly larger front brakes (330mm vs 312mm) for better stopping performance when driven hard. There is another brake upgrade poorly named M Sport Brakes that was a separate option and could be ordered with any trim package (option code S2NHA). They were 340mm in diameter and also came with 4-piston Brembo calipers from the 335. The item you are looking at is only for the M Sport trim package with the 330mm rotors.

Zimmerman rotors are finished with an anti-corrosion zinc dichromate coating over the entire rotor. This coating is applied over the rotor hat, face, and through the vanes for total corrosion protection. Even after a year of use the Zimmerman coating doesn't change color or effectiveness. The rotors are ready to use after correct bed-in procedures have been done. In addition, Zimmerman uses a high carbon content in their discs for improved thermal performance.

2014+ F32 BMW 428i - Coupe

Application note: these rotors fit cars not equipped with the factory M Sport package or M Sport brakes upgrade

GiroDisc presents its 2-piece rotors tailored for BMW's E46 M3 Competition Package (ZCP) and CSL models, providing a direct replacement for the stock 345mm rotors. These rotors redefine performance, weighing only 17.5 lbs per rotor, compared to the factory 19 lbs, resulting in a significant reduction of unsprung weight and rotational mass at the front axle.

Crafted from a proprietary high-carbon iron casting to GiroDisc’s exacting standards, these rotor rings offer unparalleled durability. Featuring 48 curved vanes acting as a centrifugal pump, they draw air through the hub for optimal cooling even during intense usage.

The 2-piece construction allows for a reusable hat, offering ease of maintenance. Replacement is simplified by attaching new rings (part number D1-012) to the existing hat.

Each essential component, from the hats to the rotor rings and drive pins, is meticulously crafted in-house at GiroDisc's Bellingham, WA facility, using domestically sourced materials. The hat is made from 6061-T6 aluminum with a sleek black anodized coating, while the drive pins are crafted from a robust steel alloy and plated with cadmium for enhanced corrosion resistance.

These rotors seamlessly integrate with common aftermarket caliper setups and stock sliding calipers found on ZCP and CSL models, including compatibility with Brembo calipers from Porsche 996 and Megane RS swaps.

Specifications:

• Diameter: 345mm
• Thickness: 28mm
• Weight: 17.5 lbs per rotor assembly

With race-ready float ensured by spring clips and Belleville washers, these rotors deliver high performance on the track while maintaining street-friendly characteristics with no noise from loose hardware. Experience the pinnacle of braking excellence with GiroDisc's E46 M3 rotors.

Genuine BMW front replacement brake rotors 

This item fits the following BMWs: 
2011+ F10 BMW 535i 535xi 535d 535d Xdrive

F06 640i 640i xDrive

F12/13 640i 640i xDrive

This is a pair (2) of Genuine BMW FRONT brake rotors/discs (370x30mm) for all F30, F31 F32 F33 and F34 models with either the BMW M Performance brakes or 335/435 with the optional M Sport brakes upgrade. These rotors are dimpled and slotted to improve brake pad feel and give the brakes a sportier and more aggressive look. In addition, they are larger that the standard brake rotors to help in braking performance. These are not a direct replacement for the stock brakes and will only work with the M Performance or optional M Sport brake upgrade.

The M Performance brakes were a dealer-installed accessory that could have been ordered new or installed after the car was delivered. M Performance brakes were larger than stock and had a colored brake caliper (red, yellow, or orange). The M Sport 335/435 optional brakes (option code S2NH or S2NHA) were available as an additional option on top of the M Sport trim package but could also be ordered on their own. They featured the same size brakes as the M Performance accessory but with either blue or unfinished grey calipers. Note that only the 335 and 435 M Sport upgrade used 370mm rotors; the 328i/428i M Sport option used a 340mm rotor. See below for a breakdown of the exact exact models and packages these rotors will work on. And for more information on the brakes for the F30/F32 chassis, see our FAQ page.

2012+ F30 BMW 335i 335i xDrive - Sedan
2014+ F34 BMW 335i xDrive GT - Gran Tourismo
2013+ F32 BMW 435i 435i xDrive - Coupe
2013+ F33 BMW 435i Convertible - Convertible

These REAR rotors fit to F22 228, F30 328, and F32 428 models with the optional M Sport Brakes upgrade (option code S2NHA). These rotors are larger and have a dimpled/slotted surface compared to what came on the base, Luxury, Modern, Sport, and M Sport trim packages. The dead giveaway whether or not you have the M Sport option is the rear caliper - the S2NHA option added 2-piston Brembo calipers on the rear while all of the brakes were a standard single piston caliper (a Brembo caliper was also used on the front for S2NHA).

These rotors were originally part of the M Performance package, which was an accessory installed after the car was delivered. It was BMW's version of an aftermarket big brake kit but these rear rotors happen to be a direct fit to 228/328/428 when equipped with the optional S2NHA M Sport brake upgrade. They are dimpled and slotted to improve brake pad feel and give the brakes a sportier and more aggressive look. In addition, they are larger that the standard brake rotors to help in braking performance, especially when driven hard.

2014+ F32 BMW 428i - Coupe

N20 engine: the rear rotors were different on the F33 428 convertible based on which engine the car has. N20 is the ULEV engine; N26 is the SULEV low emissions engine. The emissions sticker under the hood will be labeled ULEV or SULEV.

These FRONT rotors fit to F22 228, F30 328, and F32 428 models with the optional M Sport Brakes upgrade (option code S2NHA). These rotors are larger and have a dimpled/slotted surface compared to what came on the base, Luxury, Modern, Sport, and M Sport trim packages. The dead giveaway whether or not you have the M Sport option is the front caliper - the S2NHA option added 4-piston Brembo calipers on the front while all of the brakes were a standard single piston caliper (a Brembo caliper was also used on the rear for S2NHA). Since the S2NHA front brakes are the same parts as a stock 335/435, these rotors can be used on the front of those cars as well (however, there is no dimpled/slotted rotor for the stock rear brakes on a 335/435).

These rotors are the original front M Sport brakes for the 228/328/428. They are dimpled and slotted to improve brake pad feel and give the brakes a sportier and more aggressive look. In addition, they are larger that the standard brake rotors to help in braking performance, especially when driven hard.
