Hi!

Need help since I dont have a car yet to find the correct sized spur and pinion to achieve a 6.0 (or something) FDR and still have room to move the motor forward or rearward for different gearing possibilities.

The best combo of spur and pinion to achieve this with the motor placed as centered as possible.

Looking to get a T4 14 and I am going to run 10.5 Blinky.

104T spur #305874 and 33T pinion #305983 will give you an FDR of 5.98:1

What is best option:
1. 78 and 30 - 4,94
2. 91 and 34 - 4,94

I know that there is no such gear, but if I have the same module?

Is it better to be a small pinion , and a small spur

smaller pinion will spin up faster and could make the car a bit loose
