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
