Having said that, you should consider just adding a bit more camber up front. Camber won't kill your front tires. That results from excessive toe.

If those are actually what the HKS comes with then the front spring rate might be an issue. IIRC most others are in the 13-15 range in front

Your front camber sucks, throw those ******* SPC arms in the trash. Get SPL or voodoo, crank it to -3 camber and 6 or 7 caster

Check the front bumper tab which is a common spot to rub - it may not be the top of the fender. That tab can be shaved or relocated.

Also, your rear toe seems double what is recommended.
Actually your front toe seems high as well. Camber does not kill tires - toe does.

Those are common specs that many have run without rubbing
I have 20x11 +15 w/ 275/30

It is not your wheels, it’s a combination of alignment being weak, springs being soft, and fender mods
