I developed a little gearspeed calculator you guys might be interested in. Particularly handy if you're trying to compare different transmissions / final drives and tire combos. Right now i just have Miata transmissions listed - working on allowing custom gear ratios. Would love to get feedback if the tool is useful to anyone.

Looks nice. However I don't know the final drive ratios the Miata's have...

I use this simple spread sheat that started life as a Lotus 1-2-3 file. Converted to an excel program. Used it back in my Trans-Am/IMSA days. Where we changed ratios at least once a day.
Plug in the tire size, diff ratio and gear ratios and it works for anything. Copy and paste for more gears.
This website won't allow me to upload the file. email me at dave@advanced-autosports.com and I will send it to you.
