@T6180 and I discovered that there is a slight difference in hub offset from T6 to T6. We don't know why or even which T6 variations are different, but basically he had a pair of front 19" Banded steels that poked awfully on his T6. Mark ended up changing them for a new pair off Duchy and I had the poking steels off him to actually make a BBQ/Firepit out of them, because we assumed they are built wrong by mistake, and therefor useless.
Anyway, long story short, I kerbed one of my steels and whilst it went off to be refurbed, I threw one of the faulty 19s on and it didn't poke on mine. In fact it actually sat better than my original Duchy fronts and I ended up keeping Mark's faulty 19s on mine.
We still don't know the deciding factor that made the same wheel poke on his, but sit lovely on mine, other than his is a 2016 and mine is a 2017. His is manual and mine is DSG. Both T32's.
