r31 pintara are generally a good fit.. but only 5.5inch.

If you find two 7 inch ones..they are my old rear ones i had widened

Really totally depends on your strut and hub modifications.

On my 180B struts, I went from 240K hubs to 260Z hubs and got 20mm more dish on my wheels. I then used 21mm offset 6 inch wheels.

On a 1200. I personally reckon 185 is the best at 14inch and 15 inch with a 5.5 or 6inch wheel. A 6.5 or 7 inch wheel is too much of a squeeze.
