Getting a bit of tire scrub, stiffening sway bars help?
hi there
Getting a bit of scrub/heavier wear on the tire shoulders:-
Car has front 2010 GT3 bar and rear GT2 bar. Front bar has 4 holes and is one from softest and rear bar is set to softest.
Do you guys think if I set the front bar and rear bar one setting stiffer it will help prevent this tyre roll over?
Pressure wise I run 36 hot front and 37-38 hot rear! Front camber is -1.8degrees with zero toe out.

OP what's your car? That particular type of PCCB hat, 350mm rotors, spacer and rim seems to suggest a C2/4-based platform which typically maxes out at around -1.0 camber (give or take 0.2).
Like TRAKCAR said above, the important thing is how you like the car's handling. A bit more front camber will help your tire wear, but you don't want to put the cart before the horse.
Sometimes, just sometimes a wear pattern like that is unavoidable. I live in a hilly area and the curves always eat up the outboard shoulder of my street cars' tires. How many miles have you done on these MPSS'es?

You see I always thought that stiffening the bar was to help prevent roll over to keep the tyres / contact patch good.
Is that not the case then do you think?
So if I stiffen both front and rear bars handling dynamics should stay the same, so still neutral handling. But how else will stiffening the bars affect the handling / feel of the car?

Sway bar resists body roll relative to the wheels. It works through altering weight transfer and NOT by "cantilevering" the whole car on its side if you know what I mean. Hence it won't do a darn thing for your tire wear.

Needs more negative camber as many have stated.
Sway bars won't help this issue.
That's not really scrub, that is just wear. Scrub is more like when your alignment is toed in or out and it kills the tire.
GL!
