those for example?
would they rub?

 

If you still have the stock bolt pattern forget it. Stock can only take the 4x114.3 aka 4x4.5" bolt pattern. As far as I know anyway.

 

No. You have 4 lugs. The wheels have 5. Use your brain.

 

i should have specified so I didn't look like such an idiot
what I meant to ask was can I fit the width of those tires on my rx7(with different wheels of course....my bad)?

 

Not on an '83. 4x110. Only GSL-SE owners are lucky enough to have 4x114.3.

 

Most people cant fit any wider than 205 up front (problems with rubbing), and I honestly dont know what the maximum width is for the rear. But on your stock wheels you really cant go wider than 205, you'll need a wider rim for anything bigger than that.
