How do you mean "cut the crap"? Not sure why you are always so unpleasant to me, but you have been since I arrived here a couple of years ago. School bully in a former life?
The stiffness of a beam in terms of material is governed by its Young's Modulus. Changing to a different grade of steel won't change the Young's Modulus by more than a fraction of a percent, so won't ever give any appreciable difference in stiffness.
Fitting a longer hub, but keeping the track width the same, increases the axle stiffness substantially. Although the material is of about 1/3 the stiffness of the axle, it has a greater wall thickness, but more importantly the second moment of area is substantially higher than that of the axle it surrounds.
Whilst you say that I'm a "know nothing", the comment about longer hubs was because I did some testing earlier in the year with different hub lengths, and despite not being the world's best driver, could feel the differences immediately, and better than that measure them in lap times.
Are you still racing in TKM? Where do you normally race? I might not be the world's best driver, but given your continual onslaught on my character, knowledge and experience, I'd really like to know if you're actually any quicker than me. Let me know, and I'll put an entry in.
