I have changed the gearing on several 2008-10 Vipers lately and the results have been very positive. On the 2010 model they changed 5th gear to make it more usable. I have been changing 5th and 6th gear, thus putting them closer to each other. I have been pleasantly surprised how much more usable the 5th and 6th gears are. You can actually stay in 6th gear down to 50mph and still have enough power to accelerate and pass someone if you want to.

For those of you who have 2008-2010 Vipers or those who have fitted the later T6060 to your earlier year model viper. There are some close ratio 5th ad 6th (.80 and .63) gear sets available. This allows you to reach top speed in 6th instead of 5th and makes 6th gear much more user friendly. This change makes the upper gears more responsive, putting the engine in the better part of the torque range.

For those with the later T6060 (2009-10) that has the .80 5th gear, you can get just the lower 6th gear.
