If the track is technical go to a mid 4.3 FDR and 48 to 50*

For an outdoor track that's about 180 x 80 ft what would be the recommended gearing to start with for for the 21.5 motor in a touring car?

I have feedback from some guys who have gone to a 3.1 to 3.3 FDR at 48*, but start off safe

If traction is down some you may get away with it
traction was never down

Is it best to leave timing where it is set at for 2wd buggy? Run on both medium sized and small track and the small track I drop 2 teeth in pinion. I ask as I've had other brand motors whose sensor board deviations jump when adjusting the timing board. Currently my motor is set at 44 degrees. Is there an optimum timing/or amp draw for 2wd applications or best served just leaving timing as is? Thx all
