15inch ATS cup spigot rings please help

Hi, I've just put some 15inch ATS cups on my 1983 mk1 gti. Whilst the tyre fitter was putting them on he said I needed the correct spigot rings does anyone know the correct size I would need for the car? Please help 

Someone may know but its easy to measure as i doubt there is an unlimited supply in all different measurements. From memory i think the golf hub is 57.1, perhaps someone will confirm.  So just measure the diameter of the hole in the wheel, it will obviously be bigger. Then just look on ebay….

Thank you. I believe the bore is 63.4. I've emailed ats to find out for sure

Yeah according the alloy wheel shop they're 63.4. 

So you need these… or don't bother, they generally make no difference other than making it easier to center the wheel on the hub to fit the wheels.
