BBS CH center cap dimensions?

[Bimmerchop]

Can anyone please tell me what size cap in mm I need for 18x8.5 BBS CH wheels with a 5x112 bolt pattern? Face and backside if possible....

[Doc@tirerack]

70mm OD is the only # I have

70mm OD is the only # I have

Thanks Doc. I assume that's the measurement for the face of the center cap....?

That leaves me with 56mm and 64mm to choose from for the back. Still not sure which one I need

I was rummaging around in the garage this evening and saw an old BBS cap from my first set of CHs. The problem with measuring the backside of it is that there are multiple points to measure from...the OD that Doc gave is the same if you want to look at it just from the perspective of the overall cap. If you want to go based on the distance from prong to prong, depending on where I measured on the prongs themselves, I came up with 55.88mm, 58.42mm and 60.96mm (or 2.2", 2.3" and 2.4" respectively). That said, there's also measuring points on the backside that are approx 64mm apart (63.50mm to be exact)--specifically, it's the part of the cap between the prongs that would sit flush to the wheel...

Thanks twin, I'm going to try emailing BBS directly, see if they respond back soon.

That's the wrong size.

I found my answer already a couple weeks ago though. In case anyone else wants to know, the appropriate cap sizes are 70mm for the face, and 64mm for the back

Would this size also apply to the almost identical BBS CO wheels? Thanks!

That I don't know

I want to replace my BBS CH center caps with OEM ones from AUDI.

Any one can help with a Part Number?

So I guess I would rephrase my question; what OEM center cap part number got 70mm OD and 64mm ID

?

sorry to raise this thread from dead..but is there OEM audi center cap that would fit BBS CH wheels not the OEM Audi wheels made by BBS ? basicly - im seeing that OEM AUDI is 70MM front and 60MM back where people say BBS CH is 64MM in the back.. would BBS really make different cap for them? how can I get AUdi cap on non-OEM BBS CH wheels? is there a part # ?
