Hi
I know that the 14" BBS centre caps are smaller than the 15" Caps However does anyone know if the plastic centre nut/rings are the same for both size wheels.
Seems the 15" caps are premium price compared to 14" caps. I have mine but just need to renew a couple of the plastic parts that are broken over time
Thanks for advice

The black conical piece is of a much larger diameter for the 15" compared to the 14".
The whole centre assembly, which includes the tabs that break, appears to be the same for both sizes, but the samples I compared have different part numbers.

Thanks I was looking online yesterday of sellers of the plastic Nut..I noticed a lot of them didn't have the metal retaining spring. presume these were on all originals but get lost over time? Can't quite see what reason they are there for on mine??

Snap ring provides the tension on the locking tabs, pushing them outwards to engage with the wheel.
Snap ring and badge do have the same part number for both sizes.
