Hi everyone, this is my first post here but just bought a 280Z and super excited!
Anyway, I have been doing some research and from what I know, only seats 17" or less fit without doing any modification. I was hunting through google and found this thread on a miata forum...

The second poster informs OP that there is only 17" of clearance for aftermarket seats much like the 280Z. However if you scroll down to roughly the 10th poster, he installed a Cobra Monaco S seat in his miata without much modifying other than making a custom bracket. I did a little research on this seat and it says its width at the base is 19.5". Dont know if this seat would work, but if the miata has supposedly the same room as our 280Z then technically wouldn't this seat work?
Thanks,
Mike
