Audi wheel centers

[atreyu]

Hi all,

I've just got some Audi RS4 style 5x100 18" wheels for my Mk1 Cupra

They currently have center caps like these

Can anyone tell me if I can get some SEAT ones or blank ones? I've seen the small 60mm ones which go in the center but I would prefer the full size ones

Thanks
