Is this correct..?
Did a search for rollout charts/equations & this is what i found & calculated.
Final Ratio : 1 divided by 2.5 = 0.4102
Pinion / Spur : 35 divided by 65 = 0.5384
Wheel Circum : 62 divided by 3.1416 = 194.7792
Rollout = 194.7792 x 0.5384 x 0.4102 = 43.01mm
SO is this right..
Cheers
