Any help would be wonderful
Thanks Dustin
Dustin,
I have an excel spreadsheet that I created and it is set-up so that if you put the # of teeth on each pulley into it, the sheet will determine front to rear drive ratio based on tire diameter. This can be used for any 200mm or 1/8 car. The tire diameters are in a table so that you can quickly determine what size tire will give you the OD ratio you are seeking.
