Well yesterday because the track was so technical, I was using 96 spur, 39 pinion.....so I was running a FDR of 6.00
But this worked for me using a Novak motor. Other times I always use Express Motorsports 17.5 duo and my gearing would have been a little different. Since I can only use a Novak or LRP 17.5 for GT2 class, I went with Novak because they are fast and I have some experience with them. But for your car it depends on the situation. Esc, track layout, tire grip, outside temp and a few other variables will change what you use. You probably already know this though, and if so I apologize for the redundancy
If you tell me what esc you have and what motor and track size I can give you my suggestion.
