Yet another wheel fitment question

Hi guys.
I know these questions get asked a lot but its hard to ever find a definitive answer to your own exact query. 

In sort 15x8.5j et20 on the rear which I'm fairly confident will be fine out back but . . . .

15x7.5j et20 front? Probably 195/45 tyre.

I know an 8 wont fit without arch work so looking hard for alloys what aren't the typical BBS style

Car is on 32yr old standard floppy shocks at the moment but will be on coilovers before too long but will by not means be slammed, I'm too old for all that
