18x11 rear (FD)?
Damn, I've a crapload of PMs asking about fitment from this post: https://www.rx7club.com/suspension-wheels-tires-brakes-20/thanks-wheel-suggestions-winner-387407/
Answers: Yes, an 18x11 wheel will fit in the rear using the proper offset, coilovers with 2.5" springs, and tubular trailing arms. This will work with 285 or 295 or 305 rear tires. A 315 may work too, but it'd be damn close.
The trailing arm is the most critical component. My P-zeros, in 295-30 variety have about 3/8" clearance or so.
Offset? Very critical as well. Mine is +48. Any less and you're outside of the fenders, and with more you risk hitting the trailing arm. Could probably get away with +50, but I would say that is max positive offset.

Trailing arms are M2s, but they're no longer in business. I think you can get the same diameter arms from Jason or Chuck.

You might have to watch out in hard cornering with the larger tire sizes. I ran 18x10.5's with a 43 offset (more to the outside than yours) and had rubbing problems on the inside fender wall. I have the Rotary Extreme trailing links for extra clearance, but with 305 Hoosier tires in autox, I got a significant amount of inside rubbing on both the trailing arm and inner fender.
With your tire size and just street rubber, you're probably right at the limit.
I did run 17x11's with 315 Kumhos without any problems, but I've rolled my fender lip completely.
