one pro is the lower final gear for better highway fuel economy, but most 6-speeds are heavier so theres a con

The benefit of the 6 speed is the close ratio gears. However, the 5-speed is lighter and doesn't have a disadvantage over mileage (.68 vs .62 final gears). Also, depending on where the T56 came from, 1st gear could be as low as 2.66 but 5 speeds have a 1st gear of 3.38. So, what it boils down to is a road racer benefits from the close ratios of the T56 while a drag racer benefits from the steep 1st gear and light weight of the 5 speeds. Personally, I'd stick w/ a 5 speed. Another option to look at also is the Richmond 6 speed which has 5 close ratio gears and 1 overdrive gear.

A few more pros:
*The T56 is way stronger than the TR3650 that comes in most new edge mustangs. *The T56 is quieter than the 5 speeds. *The T56 is more well made and doesn't have as finicky of a shifting mechanism as the 5 speed.

You could also consider the viper spec t56 or z06 spec t56. I dont recall the ratios of those but I know first gear is fairly long in the new z06s.. its probably 3.36. Its also in the aston martin vanquish and db7, holden comadore, ect...
