Thinking of buying new wheels need help???

i have seen some wheels that are 7.5 front and rear and have an et of 12 how far do you think they will stick out the arch could someone let me know or give me some pics of what it would look like
thanks

can anyone help

they will stick out loads. i run 7j wheels with a 35 offset and they are maybe 10mm from sticking out. basing it on that yours will stick ou an extra 23mm plus probably half the extra width.  not that accurate but hope it helps.
