what are these alloys

[GuyM]

these 15 inch alloys are on my cab. i've had a good look, but i can't see any manufacturers markings on them.
i remember having some OZ wheels that had these little removable studs all the way round (that appear to have been painted blue to match the car!). it's hard to tell if they are split rims as they are a bit corroded.
are they worth getting refurbed or should i just bin then and get some 15inch bbs?.....any thoughts/ideas?
also the front two wheels are missing the centers which appear to be a bigger size than the standard bbs ones and have a different fixing screw....any idea where i might find 2 replacement ones

Yuk.....NanKangs......

They look like BBS, but you would have to have a look for marks under the centre cap or on the inside of the wheel.

I'll have them if you're gonna bin em!

Doubt they're real split rims though... You see them on eBay once in a while but I'm not sure who makes them.

this is and educated guess but they look like ultra rare Oz split rims and were a very expensive wheel option when new
