What wheel offset are these please ?

Hi All,
I’m looking at buying some after market alloy wheels, but uncertain what ET offset I need. Ideally I’d like to fit new alloys without using wheel spacers.
What offset have you fitted ?
As a starting point does anyone know what ET offset my Audi OEM wheels are?
Many thanks

Hi - nice one. All I could find was information saying that they might be ET34.
Are the front & rear the same?
So would I be right in saying that if I needed 10mm spacers to push these wheels out to fill the arch more, that for a new after market wheel with no spacers, I would need them to be ET27.5 ? ie 37.5 minus the 10mm
Many thanks for your help

Yes you'd need a 10mm spacer AND 10mm longer bolts to maintain current fit

I’m just trying to find the correct ET offset for a set of new aftermarket alloy wheels, to fill the wheel arch without using spacers.
