IIRC, It's the only wing for the RX-8 that has had any wind tunnel testing.

Yes it does create downforce but it's minimal and not until extremely high speeds.

The only other wings that I know of with any sort of CFD data are the APR wing and the Kognition wing kits for the RX8.

If you really want an authentic MS spoiler, check with your Mazda dealer. Earlier today I called two Mazda dealerships and one parts guy had no idea what to do and the other found me the rest if my MS body kit within minutes.
