I've got about 10k-ish miles on mine now and they're starting to get pretty noisy over very textured roads at low speeds. I checked and there's 2mm of play in my bearings which is the root of my knocking at lower speeds. Its annoying but not unlivable for now. Need to get the suspension taken apart to see if my thrust bushings from the OEM tops are still good but also order another set of bearings from Millway. Overall performance is still top notch and I just completed a 3k miles road trip from SF to LA then to Zion NP. Snow, rain, sleet, hail and whatnot without any issues.

I'm surprised the monoballs are so worn after so little miles. I had ~7K miles on mine before I uprated the bearings (precautionary) and the Millway monoballs we're still tight - zero wear/movement.
Of course, once some wear/movement occurs it's likely to increase dramatically so maybe the 7-10K miles range is a real world lifespan. What mileage have other folks put on the Millway top mounts so far, and are the monoballs worn yet ?

Overall, I'm still very happy with the plates overall. Hopefully the next set of bearings last longer since I don't have anymore planned extreme condition trips until around april. Driving the next couple months will be mostly city and track days.

Poly plates have just become available. Probably will be a couple months before people can put miles on them. Farkie has a set coming soon (awaiting shipment) and I think one person has a prototype set.

10k miles is pretty good. They were pretty low noise up until near the end. I'd say they're better than average having run a couple different types over the years. Most start making noise right away and I usually cycle through bearings after 7500.

I'll update the thread if mine begins making noise. I'm about to upgrade control arms as well so things should get interesting.

I have a lot to learn then. If wear is expected of a monoball camber setup, I won't be going down that route.
I then also wonder how the PU versions will hold up and whether they are a "set and forget" item or a "maintain and replace" part. |

Today I calibrated my phone's SPL meter app to my work's calibrated mic for in-car SPL measurements I'll be doing before/after the Millway street camber plate install. I want to see if the plates increase noise over things like broken pavement and large cracks in the road.

At the end of the day, it's a race car mod. Race cars rattle. The only way to get around it is either bushings, or fixed camber adjustment (that's less than ideal). It's just one of the huge downsides of our front suspension setup. Great for cost and packaging, but crappy for driving dynamics.

Yeah, but a rattle is just a rattle. What's indicated above is that this noise is due to the part wearing out, then that means it's also potentially unsafe and unsuitable for my wants and needs.
The F8x lower control arms have spherical ball joint, but do not wear or make noise over time. |

Even rubber/poly bushings wear out. They just take a lot longer and are a lot more comfortable (at the cost of performance). |

Hi Guys. I just want to chime in on the bearings and possibly wear.
From time to time we get some e-mail from customers that has sound from the bearings. But since we started to use this bearings in 2015 we had not sold one set of spares to this day with over 700pcs sold. We have however sent out a spare set to Watsey here on the forum. But in the end it it turned out to be another part that was making the rattle. I do not say that they will last forever. But we have done our best to find the best parts and materials that is avaliable. Before we make any decisions to change bearings we have some points to check. There is more likely that the sound comes from below list. 1. Steering rack, BMW knows about it, but could not easily be heard with OE topmounts. 2. Bad EDC dampers. 3. Loose damper nut. 4. Valving sound from aftermarket dampers. 5. Worn out standard dampers. Regarding the F8x lower control arms and the spherical ball joint vs Camber plates is not really comparable. It is no secret that the bearings in a camber plate are mounted in "wrong direction" and not made to take the same load axially as radially. If one were to subject the OE carrier bushing to the same loads in the wrong direction, I think it would be worn out within a few weeks. I´m curious to see the wear on Andinos bearings once he change them. If they are worn out I definitely know which guy I will send out my next prototype parts for test. :-) I hope I have been able to contribute with something to the case. //Samuel |

I've said it before and I'm happy to say it again :-)
Samuel and Millway were very helpful when I was trying to solve the knocking problem on my car. Investigations have been extensive and costly, and possible sources are now believed to be either the Ohlins R&T front dampers or the SuperPro bushes in the front wishbones. Neither of these have been confirmed yet. At 7K miles the original monorails in the Millway camber plates were still tight to the extent that they couldn't be easily turned by hand.

Thanks again for working with me to get my poly/street plates out quickly in time for me to install this weekend, get the car aligned, and ready for the track next week. Roads like the below are why I chose the poly/street plates:

If a major suspension component only lasts 16,000km before requiring replacement, I'd wager that 95% of the people that bought and installed them would not be pleased. But again, it could be an anomaly. We don't really know. Last edited by CrushJelly; 01-15-2020 at 03:36 PM.. |

If I can dumb down what you're saying... does that mean a ball joint is designed to withstand pushing forces against it (perpendicular forces) but doesn't do well when it rotates (which is what happens when turning the wheel)? Last edited by CrushJelly; 01-15-2020 at 03:43 PM.. |

In the San Francisco area, the roads are like the surface of the moon with potholes that can bend suspension components and dent wheels. It has been rated the worse road conditions in the country.
