I think the Quaife and Wavetrac are interesting designs from what little curiosity / engineering knowledge I have. Was mostly interested in the 4.10; a chance to get them at a reasonable price with interesting diff tech seemed attractive.
Regards the 3.91 vs 4.10, I would need to think on that - mostly going from the perspective of folks posting here raving about 4.10s.
It's appealing to me to use 3rd to 6th rather than 2nd to 5th - I think the shift down to 2nd is grindy, not matter how much I work on the heel toe rev matching. I assume being in the 3rd to 6th gears of the box would be the change as a result of a 4.10 final drive ratio.
Cheers,
Eamonn
