WHAT IS A CRANK HUB?

Issues relating to the standard three-piece crank hub on the S55 engine are widely known, but these are fully addressed with the installation of the MMR Performance one-piece billet crank hub and capture plate.

The OE units friction plate are known to slip, causing the timing to alter enough that piston-to-valve contact can occur and, if not totally standard and within the warranty period, leaves owners with a very expensive repair bill! We have seen several of these through our workshop, we highly recommend fixing the crank hub issue for any engine that has completed over 60,000km and is used on track days or hard downshifting.

MMR developed a product that would ensure owners of standard power outputs have complete peace of mind, as much as those that wish to increase the power and torque output without having to worry; MMR have engineered one of the most comprehensive solution on the market and at one of the most compelling price points. 

The MMR Performance one-piece crank hub is machined from billet EN36 that's been heat-treated with a 0.75mm case hardening, making it incredibly strong and durable. 

The one-piece design ensures the friction plates can't slip and with a new crank bolt tightened appropriately, this alone delivers a substantial improvement in reliability versus the OE version.

For the ultimate solution, which then also removes the possibility for this bolt to be able to loosen, we recommend an additional billet aluminium capture plate that securely houses the whole head of the crank bolt, making it near impossible for it to come undone.  

Careful design has also allowed MMR to develop a solution that's easy to install compared to some other products as there's no drilling or modification required to the OE crankshaft, which saves you time and ultimately money, too.

WHY DO I NEED IT?

If your BMW M3 F80, M4 F82, F83 or M2 Competition F87 S55 is track used, modified or heavily modified installing the MMR Crank Hub is highly recommended. A spun crank can lead to engine failure with repair costs in excess of $20,000 or if slightly luckier, broken down until vehicle is sent back to workshop for the crank hub to be replaced anyway and the engine retimed.

The SCH (Spun Crank Hub) failure has been seen on both stock and modified S55 engines. If you are modifying your car, doing track work or driving hard then upgrading the crank hub in your S55 powered M car is a fail safe you will not regret.

100% BULLETPROOF.

As it stands there is a 100% success rate of the MMR Crank Hub.

INSTALLATION:

BM Performance has extensive experience in installing thgese crank bubs including on our own F80 M3 track car. Installation of any crank hub solution is extensive and must be carried out by highly qualified technicians only, the oil pan, valve covers, subframe, steering and suspension must be removed and re-installed. BMW-Specific specialty tools are required in order to set the engine cam and valve timing.

WARNING: Improper installation may cause irreversible engine damage.

INSTALLATION TIPS:

  1. This is a great time to upgrade your turbos as everything is out of the way.
  2. For high output or high km builds it is also a great time to replace the rod bearings, everything is out of the way and ready to go for a very quick and easy installation.
  3. Many components, bolts and hardware are single-use only, please ensure no bolts are re-used during this installation that should not be.
  4. The oil system must be primed prior to re-starting the engine due to the crankcase being opened up and pressure being released.

    Mom of 3 recommend!
    Size: 5T-6T, Unit Count: 14
    I'm using these again for the 3rd time and they're great as always. My 3rd is still having some issues at night time with bed wetting, and as they get older the bigger the mess, so these truly hold up to a full bladder. And they don't smell by morning like some diaper brands. I'm usually against pull ups, but these are great for up and down ease of use and that added protection when it comes to potty training. I love the bigger size inclusion for larger children which we struggle with for comfort compared to other brands.

    ⭐⭐⭐⭐⭐ Absolute Game Changer for Active Toddlers! If you have a little one who treats diaper changes like a wrestling match, you need the Pampers Cruisers 360. We switched a few months ago, and I honestly can’t imagine going back to traditional taped diapers. Here is why they are a staple in our household: * The "Gap-Free" Fit: The 360-degree stretchy waistband is genius. It fits snugly around the tummy and back, which has completely eliminated those dreaded "blowouts" during playtime or naps. * Easy On, Easy Off: Putting these on is as simple as pulling up a pair of pants. When it’s time for a change, you just tear the Easy-Tear Sides, roll it up, and use the built-in disposal tape. It makes mid-runway-escape changes actually possible. * Skin Friendly: My toddler has somewhat sensitive skin, but we’ve had zero issues with rashes. They are incredibly soft—almost like real underwear—and breathe really well. * Serious Absorbency: Even with a heavy wetter, these hold up overnight without leaks. The Dual Leak-Guard Barriers around the legs are the unsung heroes here. Bottom line: They are perfect for the "crawler-to-walker" transition. They stay in place no matter how much climbing or sprinting is happening. Definitely worth every penny for the peace of mind (and the saved outfits)!

    Size: Size 3, Unit Count: 78
    I'm a mom of 6 and these are the best diapers. No problems. Extremely soft and comfy. Easiest diaper to get on a toddler doing the alligator roll. I put my hands through the leg holes and grab their feet to pull them through for easiest pull on. No problems with blow outs. I love the new tear off feature, so no issue with getting them off. I get them on subscription on Amazon to save money and get the big pack.

    I absolutely love these Pampers Cruisers 360 Size 5 diapers! As a parent of an active toddler, diaper changes used to be such a struggle—but these have made a huge difference. The pull-on style is a game changer. I can quickly put them on even when my child is moving around, and the 360° stretchy waistband fits snugly without being too tight. It really feels like little “training pants,” which is great as we slowly move toward potty training. What impressed me the most is how leak-proof and absorbent they are. Even during long days or naps, they keep my child dry and comfortable. The material is also very soft and gentle on the skin, and we haven’t had any irritation or rashes at all. (They’re actually designed to be gentle and hypoallergenic, which gives extra peace of mind.) I also love the easy tear-away sides and disposal tape—it makes cleanup so quick and mess-free. Overall, these diapers are perfect for active toddlers. Comfortable, reliable, and super convenient—I highly recommend them!
