Mystery Magnesium BBS?

Hello,

While browsing different types of MK1's I came across this photo of a Miami Blue Golf with a nice set of rims but it's killing me to know what they are. The guy who owns it swapped the rims for a set of BBS RS. The wheels I'm interested in are in  the first two photos.

Any help would be very much appreciated.

Thanks

Here's the link with the wheels..

I'm certain they're Compomotive splits. They're not BBS.

Hi it was my car they were image custom wheels
