FD3S 5.1 ring & pinion?

Hi, I'm looking for a 5.1 ratio or similar to fit an FD rear end. Is there such a thing, and if so, where to buy?

I heard Mazdaspeed offer one, but have not been able to confirm. I also know Mazda pickup ratios fit, but the lowest I can find is 4.77.

Any suggestions would be much appreciated.

Mazda Motorsports part number for RX-8 5.12:

Mazdatrix, same exact price:

Their part number reordered back to Mazda part number turns into:

Entering this in Mazda Motorsports search and came up with the same price as all above but no description available.
