Yeah, you would be good. Best to error on the side of caution. With ET40, you are leaving room to push wheels out a little further, with relatively little expense, using wheel spacers.

I once ran 16x7 with 195 rubber, ET42. Liked the way the front sat, but wanted to widen the track in the rear. Used 10mm spacers giving me an effective offset of 32. Liked the look, but did rub some in the rear when lowered 1.5 inches. Spacers are available in thicknesses ranging from 3mm to 15mm, with 5 and 10 being the most common.

I reiterate, you can always widen the track with a conservative offset. You cannot narrow the track with an aggressive offset wheel.

This is how mine looked with the described setup. The MK1 will be similar.
