Where can I get part numbers for BBS RS wheels parts? Is there any catalog where all serial numbers of center caps, hexagonal caps, logos, emblems ect. are recorded?

Will help me a lot to see is it possible to interchange some parts from one RS to another. Especially honeycomb caps.

Thanks

To answer myself to few questions...

I got BBS RS 098. They are Mercedes fitment. 7x16 ET35, PCD 5x112, center bore 66.6. Barrel is 5.5, center is 0.5 and lip is 1.0. Classic 34 bolts M7x24. They do not have flush back so redrill to some other 5 holes setup is not possible (it is possible but not safe) unless present holes are filled. Tricky part is large center bore so 5x100 (newer VAG) setup will be possible just with special bolts (not key 17 head but so called "tuner bolts) and not classic M12. I will redrill 'em to 5x130 since there is space under the cap and already have adapter 4x100 to 5x130. Will fit them on E30.

Now lets get to part serials:

09 24 028 honeycomb cap
09 24 013 hexagonal central cap
09 23 221 center cap 3D BBS black background/silver letters
09 24 015 plastic screw for hexagonal cap.

Hope this helps.

Honeycomb cap diameter is cca. 170mm

Hexagonal nut diameter is cca. 80mm

Center cap diameter is cca. 70mm
