As titled folks, not got car yet but noticed missing centre cap, jst want to order caps so there here 👍👍👍 cheers peeps

56mm.

 

Be careful though, a lot of non-genuine caps that are advertised as 56mm often don't fit, they're a friction fit via lugs on the cap dropping into a groove on the alloy wheel, even very small variations in diameter can result in them fitting loosely or not at all.

 

The old style caps (green) are becoming harder to source (6U0601151LMBH) and as such are quite pricey, might be worth replacing all four with the later black and chrome finish?
