Our M3 stock toe links are already spherical on both ends. The weakness of the stock toe link is the eccentric bolt that is used to set the toe. |

Rogue has some similar to what SPL has. It’s a spherical insert, not a washer.

I had no issues with mine for ~3 seasons on my previous car. Not saying that means they cannot fail though.
I just bought another set for my new build, so hopefully all is good this time around again... |

What kind of bolts did you install with? Factory bolts or ARP? How many track days through those ~3 seasons? |

I got around to doing the Powerflex Black bushing install. I'm a lot happier with this solution. I can't imagine the difference between this and bearings will be noticeable, and these were way easier to install. I used new ARP bolts for this install, torqued to 98ft-lbs.
Again not really a professional opinion but I'll certainly sleep better at night. |

I have the same feeling as well. At first I was excited to see this low cost options which can make improvement on our car. But it looks like if you do any track driving/ HPDE, the added washer for putting up the bearing can be a point of risk uncertainly to the whole thing. In the rear suspension, I already hv the solid bushing subframe. I was planning to change out some bushing to bearing, now after reading all this, I decide if I have to swap bushing to bearing, I only pick those which I do not need to add any spacer/ washer or alter to length of the whole pieces to replace. I guess one of the example would be the Rear lower control (spring) arm Inner bushing. This can be upgrade to bearing with little worries. At the end I would like to say THANK YOU to many who willing to share their "successful" and "unfortunate" experience on this topic.

Just finished a trackday Sat night. Drove 55 mins straight at Sepang International Circuit. Zero issues with the sphericals. That said I was only on AD08R tires and no aero, so not extreme amounts of grip. I did ride the kerbs pretty hard tho.
At this stage I'm comfortable with the strength/safety of the spherical conversion for anything up to trackdays. If you're a competitive driver or doing time attack or racing then probably race arms are better. |

I've been reading about this approach of removing the rubber while retaining stock arms, but I've found some other "package" approaches to this that take the self-sourcing out of it.
As an example, there's the Laptorr kit (https://laptorr.com/collections/m/E92-M3) and the Schirmer kit (https://www.teamschirmerparts.com/pr...s-gt-rear-axle) that provide full sphericals and eccentric camber arm bearing. Would this be a similar but safer approach? It definitely appears that going spherical isn't the problem but rather the improper use of washers, so maybe a "kit" is likely to mitigate some of that risk? (edit: ignoring the somewhat absurd pricing from both of those vendors, I see that SPL has the bearings for far cheaper)
