I haven't installed one, but I can pretty well promise that there's some
cutting involved. The rear braces have to mount to strong attachment
points, and your package shelf is made of tinfoil. You cut the package
shelf, and mount the bar to the frame, I'd bet.

Probably a couple of inches. At most. SCCA Solo II rules suggest that a
roll bar be no more than 6 inches behind the driver's helmet.

But don't be discouraged from getting and installing one just on my sayso.
There are good reasons to put a roll bar in a Miata. For one thing, you
can't put in a racing harness without a roll bar meeting the height
requirement in SCCA Solo II. For another, though the roll bar is of course
not guaranteed by the manufacturer, it might actually save your life.
