SR uses math to explain how our measurements are affected by relative
motion, but it doesn't explain the underlying mechanics of why those
equations work.
The explanation of a 4-d Minkowski spacetime seems to cover SR very
nicely
And what does Minkowski give for a reason why C is a constant? Why
can one ray of light never overtake another? Why the addition of
velocities works the way it does rather than just normal addition?

Because that can't ahppen whne you have lorentz transforms

That doesn't answer the question. The LT applies rather that normal
addition for a reason. What is the reason.

seehttp://en.wikipedia.org/wiki/Introduction_to_special_relativity
LTAT or LET as it is often called around here
provides a possible explaination.
Not a very good one.
Maybe not, but it works. For many that is far better than being told
"That's just the way it is. Science doesn't tell you why."

LTAT, LET doesn't tell you why either

LET says light is a wave in the aether. SR doesn't even define light
other than to say it travels at C in all frames. No explaination is
given for how it manages to do that, it is just a given. LET explains
how light is measured to travel at C in all frames even though its
closing speed with objects moving in the aether frame is not C.

The math of LET can be more
complicated than SR if you try to include the aether frame in your
calculations, but Lorentz showed how that step could be eliminated.
The math of LET can be simpified into the same math as SR.
Then just use SR and Minkowski .. no need for special ether frames adding
to
the complication
That is basicly what you end up doing. But when in doubt about how to
apply formulas at least you have a model that allows you to reason out
the result.

SR and Minkowski are the model. You introduce further complexity by having
a special frame.

What part of "The math ends up the same." do you not understand?
