Wheel fitment question

[Lozzy90]

Hi guys,
Managed to get a-hold of some Audi rotor alloys from a A3. Haven't had chance to test fit them yet but think I'm going to need spacers.
The measurements from the new wheels are 7.5Jx18 ET54 with 225/40R18 Tyres. From what I can see online the max ET my car can take is 45. So a 10mm spacer should bring me within spec.
Any info would be appreciated. Thanks.

Also was thinking of printing my own wheel spacers with my 3D printer. Not sure how a plastic spacer would cope though, thoughts?

Center bore may well be different as well although I’m not 100% sure on the A3 CB.

Well I measured the CB and it was 57.1mm which as far as Im aware is the same as the A4 so hopefully won't need spigot rings too.
