Need some for my new wheels, anyone got any?
try fitapart up near carloses wire shop
what internal and external sizes ?
what do you mean by internal and external sizes tom?
You have two sizes the outer size is needed so they click into the wheel properly as each wheel can have a different centre bore and the internal size allows it to fit onto the car basicly adapting the centre bore down to whats required.
So i need to know the centre bore your going from and to..
Hope it makes sence.
he means the internal diameter of the ring as the external diameter.
ie if the outer diameter is 60mm and the ring is 5mm thick, then the internal diameter will be 55mm
56.6 internal - about 66.6mm external.
Tape measure reads 56mm internal and 66mm external.
according to a website my car requires -Internal Diamiter 57.1mm - Volswagen / Skoda / Audi - the external diamiter on mine is - 66.6mm - for the alloys.
Does that help?
Ill have a look

Sorry m8 all the ones i have here 73 external
