Of course, Lorentz' formula "yields results that are independent of direction".

Lorentz' formula may fit to the evident increase of particle mass depending on squared velocity. I wonder if there is really compelling evidence for time depending on v squared: time dilution, length contraction and all that.

While the Doppler effect plausibly depends on the sign of relative motion, the claimed by SR time dilution and length contraction of light signals in vacuum correspond to...

Maybe you are confusing them with the plausible effect that is named after Christian Doppler:**As well known, the frequency of a signal, which is emitted or reflected from a body in motion relative to the receiver, is either blue-shifted in case of decreasing or red-shifted in case of increasing distance**."
