WHAT??
You don't need charts or graphs?? You need math!
** Note: this formula is for pan car 1/12 or 1/10 scale cars with no trans..
ROLLOUT FORMULA:
Rollout = tire size (inches) X 3.142 X Pinion size / Spur size
To find pinion size at a certain rollout the Formula is this:
Pinion = Rollout X Spur size / Tire size (inches) X 3.142
Just rotate the formula to what you need...and keep it smiple! :thumbsup:
