Quaife diff ratio choice

[Spike]

To those of you who have bought a quaife gearbox with their standard ratios as advertised, and for predominatley road use which diff ratio of the two have you chosen? i assume it would be the 3.750 but i would like to hear the argument for the 3.50 if there is one?

This would be with 15" wheels fitted with CR6ZZ tyres

Cheers

This might help.

Comparison of 3.50 and 3.75 final drive QBE62G speeds in gears, shifting at 6250 rpm. Same wheels and tires. I chose the 3.75 although I never was able to get it and went with the RBT instead.
