Rims change to flush against fender

Hello all, appreciate if the folks out there that did a rims change can advise the offset for a fender flush.

I am getting my brand new mark 3 superb l&k this aug and is thinking of ordering a custom made forge rims for my ride. The stock 220 version comes with a 19 inch offset +44 on the 8j width wheel

Any idea what is the offset for a 19 inch 8j width wheel to achieve a fender flush ?
