thanks crash, what do you use to figure that stuff out?
|
I use and most everybody on here uses GEAR CHART
Pretty easy formula though: tire size * 3.14 = A Spur gear / Pinion Gear * Internal Drive Ratio = B Then A / B = Rollout Example: 55 * 3.14 = 172.7 112 / 44 * 1.7 = 4.33 172.7 / 4.33 = 39.88mm Later,:) |
thanks again crash, next dumb question how do i know what rollout i want to achieve?
