It's either Corteco or Lemforder. Either way, you get the same mounts if you buy from either brand.

I continually see people saying to avoid VAC parts (particularly Obioban ) I bought my rod bearing kit from them before I saw any of this, should I be worried? I've never seen any explanation behind these claims, so can anyone provide some evidence? I really don't want to have my freshly rebuilt engine shredding itself on me...

I think it also depends on what part youíre replacing. Water pump, control arm etc, Iíll go oe as you guys say. If itís a trunk shock, bolts, or window seals Iíll get whatever is cheapest.

From my experience working in the auto parts business I often saw Trelleborg and Freudenberg mounts for many European makes. I'm not 100% sure for the E46 M3, but I wouldn't be surprised if it was.

Like a lot of places, it seems they don't actually do as much of their own manufacturing as they let on. If you poke around, people have been screwed by their shop, and products outside of stupid simple billet seat adapters etc. are poorly made. I have some brackets from them which are just fine, but the only "big purchase" I've had interaction with was a buddy who got a diff for his 135 - after talking to them on the phone, it became apparent that VAC wasn't actually doing the work, they were sending his diff off to another company and sending it back to him.. which wasn't really disclosed on the site.

Frankly, there aren't that many parts you can just get elsewhere - it hasn't been much of a problem to just avoid them, personally.

Under the rules of this forum am I allowed to provide a link to another M3 forum? There is a similar thread on a UK forum.

Their VANOS hub is interesting, but I don't trust it because of VAC's reputation. Otherwise would be a good option for those who have broken tabs.



Turbotoy's is nice and what I have in my car. But I do prefer the idea of a new machined piece rather than a ring welded to an original hub.

Generally that's fine. Exception would be things like group buys which we'd prefer run on this site.
