not very good with wheels, but they look like early buddyclub p1's to me. or possibly enkei wheels.
as said, look on the inside of the rim and all over the rim as there could be a brand printed on there.
Hmmm similar mate but the rim of the wheel is more curved on the mx5 wheels. So they're not them and they're not early p1's. I still think they are some sort of enkei wheel but I have no idea. Interested to find out though. I quite like them
If they are enkei they would be stamped up enkei - made in japan and they would also have that weird squiggly thing on the front. not here to criticise just to help
