Bent front suspension stabilizer and uneven tire wear

Bend front suspension stabilizer and uneven tire wear
I was changing oil yesterday and luckily found the massive inside wear on one front tire. My C7 is lowered on stock bolts, all the way down, and I installed aFe sway bars, front and back, a couple years ago. While the rear acts funny at high speeds I never bothered to get an alignment. Never had an issue on the front, the car goes very fast through corners, no surprise with that negative camber.
Obviously an alignment and new front tires are in order.
While I was under the car, I also found a slightly bend "front suspension stabilizer bar", see photos below. Only one side is bend, the same side as the worn tire. When I flex it down, the front suspension cradle doesn't move at all, the bar flips right back up when I let go, so I don't think this has an impact on tire wear.
I do not recall hitting any curb etc. I'm the only driver, that being said, I drive her very hard.
Here my questions:
1.) What is this stabilizer bar called, what is the part number?
2.) Should I replace this stabilizer bar?
3.) Do you think this had an impact on tire wear?
4.) Where can I find a good shop for the alignment around Tampa Bay / Sarasota? They need to have access to the caster alignment tool.

Chassis reinforcement, but I doubt it altered your alignment.
If the front Toe is good (not too much toe-out), then the tire wear is too much negative camber coupled with too much cornering enjoyment.....got to pay to play....

Just a chassis brace. Has zero effect on alignment. The bend looks so minor you can probably straighten it.

GM used to sell carbon fiber replacements. Supposedly a couple pounds lighter in total with all 4, but mostly for the "Look at Me" bragging rights crowd.

Thank you guys very much for the help and input, I really appreciated it.
I indeed drive the heck out of my C7, usually late at night when nobody is around. There are a few slower corners with no traffic that I love to carve. I should go to the track, but I'm tired of that routine. Done that for years when I was racing in Unlimited Superbike class. When they closed down the best track in FL, I was done with track prep and hauling my stuff around for days.
At that low price I just replace it, for good measure. Thank you for the link.
Now that explains it all, and very well.
Will I need a shop that has the tool to adjust caster, or will I get away with a regular alignment? I'm having a hard time finding a shop that has the needed tool. I sent 3 emails so far and nothing.
Also, the rear acts funny at higher speeds and I wonder if this is caused by the aFe sway bars (link below). If I remember correctly, I have them on the stiffest setting in the front, and middle in the rear. The car is super planted, will even have a wheel in the air when I drive off a steeper driveways sideways. Zero body roll, and I love how it handles at speeds up to 80. Past 100 and it feels dicey. Just a small input at the wheel and the rear hooks hard and comes "around" instantly. Incredible traction but if I would lose it, I'd be off the road in a split second. This gets especially bad with new rear tires. Is it the same "increase wheel camber" issue due to the lowering? Do you have any other ideas regarding this issue?

The wear is due to lowering the car. As you lower the car you increase wheel camber which at the same time changes the toe settings. As the top of the wheels leans in the suspension pulls on the tie rods which at the front of the car are connected in to the knuckle in front hub. Since the tie rods can't move when the suspension pulls on them the wheels turn inward (causing toe in along with the increased negative camber).

I sent him an email earlier and he suggested Lowe Auto Repair. I guess he doesn't have the caster alignment tool. I'll call Lowe Auto Repair on Monday, but never heard of them before.

Called, they don't have the caster alignment tool. Tech didn't even understand what I was talking about.
This suggestion didn't make sense to begin with. I need a proper alignment if not race shop for my suspension setup, not a random tire chain place that works on $20,000 Altimas all day long.
