the ofset is where the hub mounting face is relative to the centre of the wheel rim, 0 ofset would put the mounting face in the middle of the wheel, yours at et -7 would put the wheel centre 7 mm in of the centre making these wheels stick out a long way, would need big arches

you say "in by 7mm", its actually out by 7mm,
for example if you have wheels with 0 offset and you change them for wheels of -7 of set it is the same as adding a 7mm wheel spacer.
just by the mention of -7 offset I presume you are looking at 7x13 rims, as a comparison the spots pack rims are 6x13 with +21 offset, offset wise that's the equivalent of a 28mm spacer.
