If you have similar programs you'd like to share, let me know, and I can post them up here for reference.

 

 

 

Thanks

Does anyone have that Miata tire rollout calc?

Al, what does it do?

Hey Tom.

 

 

 

Maybe runout isn't an accurate term.

 

 

 

It allowed you to calculate what speedo variation would be for any number of tire and wheel variations (lots of diameter and aspect ration combos)...so for example, if your speedo was calibrated for 14 185/60, it calculated what the error would be if you switched to say a 15 195/45.

 

 

 

Someone had posted it on Se7ens.net, and it's where I got the notion that my speedo was off by 9.5%. It would be good to have that link here at USA7s....I bet Keith Tanner knows where it is.

Al, something like this?

You can type in fake stuff for your gear ratios, change tire parameters and see % difference.

How about this:

Needs a bit of formatt tweaking for my tastes, but assuming the calculations are correct, looks pretty good.

This one was simpler...didn't need to know ratios.

 

 

 

I'll try and find it.

[Al N.]

Found it!

Better formatted combination of both the gear calculator and the corner weight spreadsheets.

Should probably add more gearbox details (like the BGH boxes).

Anyone have additional gearbox ratios we could add to this spreadsheet?
