Guild Wars 2

I have just seen the endless mystery cat tonic and want to use it in wvw for “fun”…. If I use superior traveller rune set will the speed be retained even after I have transformed? And also will movement signet effect the transformation. (The only one I have seen is centaur runes and “6” spamming)….. I have also heard traveller runes also affect seige golem speed is it true?

I tested traveller runes on golem and it seems to work but speed bonus on slow moving golem is very little anyway.
