Any negative side effects of TRD sway bar?

[detroiter]

I know, I really don't want to start a million threads about the sway bar but I'm a thinking type person and always have questions. I started getting to think if there is any side effects of having the trd sway bar? Does it wear out the edges of the rear tires faster since there's much less "flex" from the suspension going with the car when it goes around a turn or does it make it any "harder" of a turn since theres less give in the rear suspension?

It just makes me ask because when I was looking at my tires today since putting the bar on, the front tires driving surface area is completely white (From the salt residue on the road) but the rears, it seems like the outer edges of the tires are saltless. So I'm trying to figure out why it's like that, is that surface of the tire not touching the road because how stiff the rear end is now and less leeway? I don't believe it's any sort of alignment issue because the car drives fine straight and doesnt pull.

Maybe I'm being dumb and paranoid?

Just want to cover all my bases I suppose
