Today was the second day in wonderful weather I drove the nice Eifel area B-roads. Yes, the Mazda gear ratios are fine. But...the axle ratio would be better if it is shorter, 3.9 or 4.1.
And the 5th still would have enough reserve not being too short when driving a motorway.
I wrote that 2 years agor Techniques and Williams told me that I cannot chage the diff concerning the BTR axle but I must buy a whole axle which is too expensive for the fun of it. Does someone have new infos, is it possible in the meantime to change the diff only?
Now, if anyone says, why don't you just downshift to get higher revs? It's not the same thing.
With the shorter rear axle ratio, the lever and thus the added torque is in each gear equally effective and that at all revs.
The fact that the Mazda transmission has the small gears "longer" is all the more advantageous with a shorter rear axle ratio.
