The only marking in the back is what looks like the year of production and just says made in germany. All the stud pattern, offset details e.t.c. are stamped in the centre front of the hub. They were not previously refurbed , but I have just had the centres refurbed so am sure the mark was not there. I've seen this mark on some other wheels too (apart from Borbet's) but nevertheless not all wheels have this as my previous Keskin wheels never had this either.

Thanks mate. I have the offset stamped and everything on my set near the studs, so don't think they're a re-drilled jobbie. Only wierd thing about my set is that the 7.5x16's are ET30, where as i thought they only came in ET20. Also the wheels don't have this mark on them... which i beleive is a quality control/production standard mark or something

Oh ok, would it be perfectly safe then to use them then?. I did email Borbet yesterday too and this is what I got from them as a reply... "The 5x100 fitment was never made by Borbet in the type A wheel. The centre section of the wheel is not strong enough to take 5 stud holes as close as 100mm. The 5x112 was ok as the holes were further away from the centre bore. The wheels you have will have been drilled by someone once they'd been bought as blanks from Borbet" Loads of people seem to have 5x100's though, surely the last line is incorrect?!

I have heard that Borbet A's in the 5x100 fitment (or any 5 stud drilled pattern) had a problem of the hubs not being strong enough and thats why they have now seized production of them. Does anyone know if this is true?

Can anyone please tell me what is the factory finish that Borbet A dishes come in. Is it bare metal polished Metal polished and laquered Or Diamond cut and laquered At the moment i think mine are bare metal polished but I don't think this would be the original finish :? They are going on a daily driver so I probably won't have the chance to keep ontop of keeping the polished finish. Therefore, i'm after the best finish that will keep them looking shiny, but also require less effort than bare metal polished to maintain them. Thanks

Thanks for the reply mate, that does help. Because it does appear to look like 60 degree tapered wheel bolt seats but when you feel the seat you can see its slightly rounded too. Think this is because someone previously may have used the standard 'rounded seat' VW bolts on them hence causing this little indentation. Just want to make sure I make use of the right bolts when I fit them.

bump, anyone?

Does anyone know whether borbet A's use rounded (standard vw) seat bolts or tapered seat wheel bolts? Here's a picture of the wheel studs, although most aftermarket wheels have the tapered seat's these also seem to look like rounded bolt seats. Can anyone tell better from this picture? (they are ET30 7.5x16's)
