Trying to confirm your question, your asking because you have to run a harder tire is there anything you can do with the set-up to help compensate for that ?
Then I'm curious WHY you have to run harder tires ? your not allowed to prep ?

softer tires on our kart seems to wear [ feather quicker] need harder to show better wear] some karts are running 45 duro and we are at 54

You got more tire issues than set-up, Give details maybe we can help better, which chassis ? current numbers & Cambers ? which tires ? which class motor and weight ? normal prep routine ? Internal prep ? Air pressure ? Describe normal track conditions ?

Just to answer your question If forced to run softer than needed, add some left, add some RF camber, take out some LF camber, use as much rear stagger as you can get away with without rear breaking loose, use little more air pressure just to name somethings.

Where are you finishing in the race ?
Just wanting softer tires is not a good point unless you have a valid reason.
When your soft tires wear more in a race, do you finish closer to the front ?
What are you looking to gain other than softer tires ?

they are suppose to feather a little, if you come off the track and the tire is slick its not working

Just because your competitors tell you there tires duro at 54 and your are 45 that may not be the case , if they're using an Intercomp duro and you're using a longacre that right there can be the issue ....a longacre will read higher # then the Intercomp and if you're chasing there #s that's why you think you need a harder tire ....

Like it and I'll add could just be the way there using it vs yourself, also could be there checking at different area of tire than you, don't get hung up on just duro numbers regardless.

and just to clarify , the 2 durometers wont be 9 points different but they are different , Another variable is rubber thickness , if your tires are thin you can actually be reading cords
 
Tires #1: worked heavily with a deep base of a HL-2 style prep to duro 45

Tires #2: a few coats of an aggressive/softening style prep to duro 45

Both tires duro 45, but both tires do NOT work the same.
