I found the information you recieved did not make sense, so I called Dynamic Tyres myself.
The answer is;
16x7 & 16x8 are both +30mm offset for the D2, wheel and tyre centre will be in the same location.
16x8 is only available in black with the round holes.
So, as mentioned they will fit as the tyre location will not change.
If you want to check for yourself the details are below;
