Pure racetrack DNA: The new centrelock wheels from the BMW M Performance Parts program.

Munich. The retrofit products from the BMW M Performance Parts program not only enhance numerous current BMW models but also provide an additional touch of motorsport feeling to the high-performance sports cars of the BMW M GmbH. Among the particularly notable examples of technology transferred directly from the racetrack to the road are the centrelock wheels, available for selected high-performance automobiles. Design and functionality make these lightweight forged wheels absolute highlights in the diverse range of BMW M Performance Parts.

With their optimized weight, emotionally charged design, and technology adapted from motorsport connecting to the wheel bearing, the centrelock wheels emphasize the high-performance-oriented character of the vehicles equipped with them. In the case of the special edition BMW 3.0 CSL, presented on the occasion of the 50th anniversary of BMW M GmbH and sold in a limited edition of 50 units, they are part of the specifically tuned racetrack performance chassis technology. Currently, BMW M Performance centrelock wheels are offered in the Original BMW Accessories program for the BMW M2 (combined fuel consumption: 9.9 � 9.6 l/100 km; combined CO2 emissions: 223 � 218 g/km according to WLTP), the BMW M3 Touring Competition with M xDrive (combined fuel consumption: 10.4 � 10.1 l/100 km; combined CO2 emissions: 235 � 229 g/km according to WLTP), as well as for all model variants of the BMW M3 Sedan, BMW M4 Coupe, and BMW M4 Convertible.

BMW M Performance centrelock wheel: Wheel change like the pros.

Centrelock wheels were developed for motorsport, where they enable particularly fast wheel changes and, consequently, short pit stops. Instead of the usual five screws, each wheel is attached to the wheel hub with only one central screw. An extremely solid connection is ensured during the installation of the central locks by applying a torque of 930 Nm. This technology not only makes pure racetrack DNA tangible during wheel changes but also reduces rotating masses and optimizes the exclusive appearance through a distinctive design in the hub area.

The M Performance centrelock wheels for the models of the BMW M2, BMW M3, and BMW M4 are offered as a combined set in sizes 19 inches for the front axle and 20 inches for the rear axle. The lightweight forged wheels in Y-spoke design, in Jet Black matte color, feature a milled M Performance lettering and come equipped with tires in dimensions 275/35 ZR19 for the front and 285/30 ZR20 for the rear.

Individual motorsport characteristics for exterior and interior.

Like the centrelock wheels, other products from the BMW M Performance Parts program are based on the development know-how and more than five decades of motorsport experience of the BMW M GmbH. The diverse range includes retrofit options in the areas of suspension, drivetrain, aerodynamics, and cockpit, enabling a performance-oriented customization and providing a racetrack feeling in everyday traffic. For a targeted boost in dynamics and agility, options such as the M Performance suspension with height-adjustable spring perches and the M Performance sport brake system are available.

Additionally, the athletic appearance of a BMW M car can be enhanced with model-specific carbon components. The BMW M Performance Parts for the exterior are mostly made of carbon fiber-reinforced plastic (CFRP), sealed with clear lacquer for a high-quality finish. Model-specific options such as the M Performance front attachment carbon, the M Performance rear diffuser, or the M Performance side sill insert carbon give the vehicle a characterful appearance in a racing-style.

The uncompromising quality and special aesthetics of the BMW M Performance Parts are also experienced in the interior. High-quality carbon and Alcantara elements convey the motorsport genes of BMW M into the cockpit. M Performance knee pads with Alcantara surface provide optimized grip during particularly dynamic cornering. And both the M Performance steering wheel Pro and the M Performance armrest Alcantara offer perfect conditions for an especially intense driving experience.

I admit they�re drool-over cool looking.
Downside is you need a full Pit Crew to use them� one person to center and hold the socket, two more people to pull on a 6-foot breaker bar to loosen, and another to hand them the 6-foot torque wrench. The center nut requires torquing to 930Nm (that�s about SEVEN HUNDRED foot pounds).

Welp, you broke the internet today.

The nut looks awesome with the machined logo.

Will retrofitting these wheels require a new hub?

If you employ modern technology and use a cordless impact gun with a center lock tool removal/reassembly is a non issue.

Other than honoring the marketing copy of the announcement, what would be the value of using these in daily driving?

Naaaaaah just drop another $5,000 on the proper impact gun and you�re ready to hard park.

Of course.

All the benefits of lightening unsprung and rotating mass.

The price tag though!

Utterly pointless

So when are you guys fitting them to your M2?

[TopJimmy]

I can already see someone dropping $10K per spindle kit and $6K per wheel, then using a Milwaukee 1400Nm cordless to feel like the pit-crew zip-gun-guy�which does remove the nut. Then they zip it back on to one or two �dunka-dunks� which overtorques it. Now they drive to Pep Boys or Firestone to get help (or go complain to Home Depot demanding the cordless was defective).

If you can afford $64K for the wheels and hubs you surely can afford to pay someone to do your wheel work. This option targets the very wealthy, who might have the dealership swapping and storing their winter and summer sets.

Filthy Rich:
Two sets of center locks? Pah! I have a third set being coated in 24K gold, just to see if I like the look! Now let�s go find peasants and run them off the road�that�s so much fun!!!

It�s funny seeing people with no experience with CL cars saying that you can just use an impact to zap these out LOL. It�s not a cup car CL system, it�s a aluminum nut that you have to baby and put on antiseize every time and follow a specific tightening, lossen a few degs, and retighten. At least that�s the case for P cars, I don�t see it being different on a BMW application. Please don�t use an impact on a road CL system. It�ll quickly become very expensive. The hytorc gun is a planetary gear reduction precision machine that has nothing to do with an impact, thus the reaction arm. These are just for hard parking. People are willing to sell their soul to convert their CL on a P car to a cup system or a 5 lug.

You�re only right if you consider lighter wheel and hub assemblies pointless.

Within the performance envelope of 3800+ lb street cars, it is pointless.

I disagree and don�t even consider the topic debatable. Lighter wheel and hub assemblies objectively provide a performance improvement. Anyone who argues otherwise obviously hasn�t ever experienced what heavier or lighter wheels do to their vehicle.

Fun fact, that particular gun made by obsessed garage is not impact. It is electric motors with a bunch of gears inside. Porsche specifically says never use impact tools on their center locks. Which kinda defeats the purpose of a center lock but oh well, still hella cool tho.

[Tag]

930Nm (686 ft-lbs) to tighten, up to 1,600 NM (1,180 ft-lbs) to break free.

Two G80/2C and a G87 combined make enough torque to break it loose. Then send your G87 buddy home, the other two cars can handle it from there.

Without seeing a combined weight reduction for this, we can't know how much has been removed and if it's comparable to just getting a lightweight, forged wheel.

You're wrong, but that's ok. G87 has cast wheels and the objective data shows it is not really worse-off for that. People think they feel a difference, it's just placebo and usually they changed tires at the same time which always makes a huge difference in feel. It's a heavy street car. No one is going to tell the difference between a centerlock and 5 lug.
