I'm moving to 17.5 blinky from 13.5 timed and need to get a new set of pinions and spurs. I understand that 17.5 can be geared down as low as 3.2 on a large track and wondering what combination of spur/pinion people are using to gear this low (I understand that not all combinations will fit). |

what car have you got? because different cars have different internal ratios. if you have one of the T3 series the internal ratio is 1.9 so to get dead on 3.2 you would need 44 pinion and 74 spur. |
