Hi all i have finally worked out my gear ratio which is (2.6:1) my tyre diameter is 205mm and my car has standard 61t spur and 19t pinion .I am trying to set the car up to get a roll out of 40 .
I still dont know what to do to get it there ,what spur and pinion do i need to use.
Any help would be greatly appreciated
