Are all tsw hockenheim centre caps the same diameter from 15" right up to 18"?? I personally think they would be same due to the centre of the actual wheel would still need to be a certain diameter for the lug holes and strength outside of that.

But just asking incase there is a difference. Im short of centres and need them

 

I'm pretty sure they are all the same size. Just watch for fit ment tho. My imola centres don't fit my evo's.
