For an OEM wheel i.e ET51 and 7.5j on a 340/345mm disc you need a 12mm spacer. ![happy2 :happy2:](https://www.mk5golfgti.co.uk/forum/Smileys/newsmileys/happy2.gif)
What about pro race 1.2 et45 18"
Assuming they're 8j then a 5mm spacer should be plenty, my wheels are 8j et45 and they clear by about 1mm or so and they have actually touched at some point
