Not likely. The Rx8 shares a R&P with the FD, so it's almost certainly an 8" and not a 7".
4.778 7" Kia Sportage gears are virtually impossible to find in a junkyard, but they can be had brand new for <$300.

I looked briefly in ~2013 when I was building my 4.77 OSG for PTE and had no luck. They were also so cheap brand new that it was hard to justify taking a risk on used gears (already spending ~$300 on setup, not to mention the $1600 diff).

I used the 4.778 with the Quaife Wide. this makes second gear about the same as the 3.636 six peed actually a bit faster
For track purposes only Id probly run a 3.909 with the six speed and a 4.30 with the Quaife. Neaither of those transmissions has proven to be bullet proof reliable however with over 300ft-lbs of torque but the gear ratios are not bad.

They are, but they were also in cars that had at least another 1000lb on them. I would have used one behind my engine if I hadn't gone with an ls3, they're way lighter than the t56 which is like 130lb. But there's plenty of high 300, low 400hp 302 miatas running around. How many of them are tracked I couldn't tell you, but t5s can also be rebuilt and bought used for nothing.
