I've been thinking to switch to 3.46 or 3.38 differential ratio. If you recall, the Z8 has 3.38:1 ratio with the same gearbox. In addition, the car will be drag limited, anyway. The car has 365 uncorrected HP using Bosch. I'm affraid that the 1st year will be totally useless if I use a larger ratio. However, I can use the powerband better with a larger ratio. Opinions?
