MX5 SE Gear Ratios

[Roadrunner]

A mate put me onto a phone app called PerfExpert. Essentially a virtual dyno that's apparently pretty accurate, so thought I'd give it a go just for shits and giggles.
To be most accurate it needs a fair bit of info which I've found through google searches, however struggling with the simplest one; Gear ratios. I know the rear end is 3.63 but I also need:
- 2nd 3rd & 4th gear ratios for 2004 SE Turbo 6 speed gearbox.
Does anyone know these?

I 'think' I have the Drag Area sorted. Perfexpert wants "Cd.A in metres square". "This is the drag coefficient (Cd) multiplied by the frontal area (A)"
Searching brings up some US sites including Wiki saying 0.36 and I found on the old Mazdaspeed site someone actually measured the frontal area at 20.331 square feet. So converting to metric it's 0.36 x 1.88881171 = 0.68. The app says usual measurements are between 0.5 and 1.5 so I think this should be right unless someone has more accurate info?

Cheers.
