Though the TPCRacing Adjustable Toe Links are physically smaller than the OEM units, you must take into account that our units are constructed from forged pieces of material. On the other hand the factory pieces are cast, which means that they would need to be bigger to carry the same loads as the forged pieces. Also, while the factory piece does appear bigger, you must also consider that it has an H-Beam design that makes it appear to contain more material than it actually does.There is no rubber bushing in the TPC item and the ball joint looks substantially smaller. A lot of racing equipment is designed more for adjustability than durability. I think without the rubber bushing the TPC item would give a much more uncomfortable ride over road surfaces with the ball joint taking a lot of punishment. May well be of benefit on the track but not something i'd want on my road car. As to the idea of the eccentric bolts slipping , this seems crazy as its the same design employed on the GT3 which really is a track orientated car. If you are serious about track driving you should be checking and setting the geo for each circuit anyway.
With all due respect... Aurora makes very nice rod-ends. I typically use them (at work) when/if cost is a factor. However, from my experience, there are others that are higher quality and that have a longer life. NMB, NHBB, and Goldline are examples - however, sometimes cost gets truly ridiculous....Those in the know, know that Aurora makes the best rodends money can buy; there is nothing stronger, more reliable, or so well manufactured.....

Again, I think Aurora bearings are very good; in fact they are what I would spec if I had designed your toe links. I just don't enjoy when people make sweeping statements. The truth is there are many strong competitors for most products - especially aerospace-based ones like rod-ends.
I also agree that your toe-links shouldn't affect ride and may make handling a bit more stable on-track. They also obviously afford a broader range of toe adjustment. The biggest side-effect I would expect on the street is a small increase in noise level.
I also agree the eccentrics should not slip when tightened properly.
No offense intended, and best regards,
