I run a 4.11 and a 6.20. To be honest with you after using the 6.20 it just sucks to use anything else. Gives you a lot of extra punch, especially from a short distance. Have had a lot of people tell me that its to much for mud, but it has never gave me any problems. It also makes it a lot easier to push other cars around.

I was pretty happy with my 5.13's. I won't go any deeper than that though behind my built motor. Gonna try them behind a stock 318 next year.

i have used 5.13 gears haven't really gotten the full effect out of them but then again i dont know anything but 5.13 gears they held good behind my 318 though only time i got to notice a differance was i drove the car around when it had 2.73 or something like that in it stock and i could notice a differance there.. i think it all really depends on your size of track and how many people they normally put into it around here the tracks seem big and have alot of room to move around too low of gears you risk floating your valves if your not carefull
