OZ Polaris Wheels - what size centre caps?

[jools182]

Hi

Has anyone got Oz Polaris wheels?

I'm trying to find out what centre caps will fit

I've measeured the wheels and it's around 50mm opening, which widens out at the back to about 54-55mm

I've had 2 sets of centre caps from ebay, neither of which fit

I bought caps off these guys http://www.performancealloys.com/oz-racing-centre-...

Albeit for different wheels and fairly pricey.

52mm internal and 56mm outer OZ centre cap would be my guess. Also what size are the wheels as I am not 100% certain if 14/15 inch variants have different size caps to 16/17 inch versions

Do you have any of the caps as there is a number stamped on the back of the centre cap which you can cross reference using the website posted above - a VERY good site and one i was going to post a link to!

Thanks

They are 15" on an MX5

The problem is the caps that are on don't fit perfectly. They are a VW part
