My car is currently setup for 17.5 blinky with a FDR around 4.0 so I have a few pinions around the 45-47T (64P) range. In order to use those pinions in USGT, I would have to drop the spur from 96T to somewhere in the 81-85T range. Does anyone run spurs that small? Would there even be enough adjustment range to properly mesh that range of gearing? I know buying bigger pinions is probably easier, I'm just curious if people have tried this in the past.
i currently run a 88t in my tcxx.. but i've had as small as a 84 and 86 in the car - that got me down in the lower 3 FDR
