hey, i am using ROH 18x8inch rims with 35+ offset....the plastic wheel hub rings have crumbled to pieces and causing wheel vibrations at high speed...as to be expected when they break......I can get them off ebay but i need the exact size....does anyone know what size they are

or my tyre shop can make them for $25-$30 each ring.....which is a joke...as ebay sell the set for $20

any metal ones are the ones im going for


thanks

I think OEM is 67.1mm and most aftermarket is about 72mm? There's a mob on eBay that sells metal rings for about $30 which I've used before without issue.
