Hi, I had my first offroad race today in a 2wd b4 with a 21.5 motor.
I thought with this I'd be quite even with the field but I was at least 7 seconds a lap slower and was told it's to do with my gearing.

I've read a bit about it but still seems confusing. What set up do I need to look at for a 2wd B4 running a 21.5 Reedy Mach 2?
