Rolling Radius Question 325/330 SP/nonSP

Looking for help. The brochure gives gear and final drive ratios, but I have not seen mph/1000 rpm figures.

Does anyone know if the different wheels on 325 vs 330 and Sports Pack vs not Sports Pack makes a difference to rolling radius, and hence the mph/1000 rpm?

I want the data to build into an Excel model, which, if I get it working, I'll publish for you all.

Cheers

John

Tire size calculator including rolling radius:
http://www.miata.net/garage/tirecalc.html

Rolling radius should be approximately the same for all E90s...

why use miata.net's calculator when we have our own in the wheel and tire forum (at the top of the forum).

as for the diameter, the overall diameter is the same no matter which e90 you get.. the larger wheels on a 330 is balanced by smaller tires to achieve the same overall diameter, which is the key.

I need one mph/1000 rpm number please. For a USA version, 325 or 330 (need to know which), auto or manual (need to know which), and if it's not for 6th gear, please tell me. Thanks!
