What would be the wheel offset req for 20” aftermarket rims.
You'd need the rim width to determine ET, seanick, and the tyre size too.
For sure I don't recall a 20" rim being reported anywhere as being successfully fitted on an 8P RS3 with STD wheel arches and for some even adding a 'wider' tyre and/or spacer to a 19" OE rim has caused fouling problems.
But try here for more information: https://www.willtheyfit.com/index.php?
And good luck...
OEM RS3 20X 8.5J on 225/30/20 tires should do the trick. Adam Hodge did in on his S3 with widened front arches which may be the same width as the standard rs3 otherwise replacement arches available
