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.

wow thats nice..very clean..didn;t think u could fit that much tire under there..must have been alota work tryin to find a perfect fitment..but u had to make tubular trailing arms..or buy? which make?

 

Exactly, it's pretty much the max you can get under there. Kinesis was the only wheel manufacturer in the US aside from BBS USA ($1400 per wheel!) that was willing to work with me on various offsets.

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.

Sorry I posted asking for a link in the other thread. Didn't see this here.
