That really comes down to your clutch, IMO. The 5 speed needs a 5th gear nut installed, cause they have this little problem, that I don't actually know too much about, but the splines can strip over time. I think if you are running really high power, anything over 450rwhp, you will probably want a bigger better input shaft. And the 6spd may have a slightly larger one stock, but I'm not sure about that. The 6spd is rated to tow more, if that is anything to you, I think its rated at 26k and the 5spd is 18.5k. Anyone please feel free to correct anything I said that needs correction.
