Like @BOTSLAYER and @aldebaran said (tho FWIW I said first a while ago) looks like there is an extension bias in your squat which could be contributing to ur hip impingement issues.
There’s a couple of elements to this but the gist of it is that neutral spine positioning makes breathing and bracing good which makes lift heavy good.
We are looking at your torso segment where the magic happens. The body can generate an incredible amount of stiffness and stability facilitated by neutral positions (+ other benefits to ROM, impingement etc.).
We are interested in everything from the pelvis up to our our ribs, this is what makes up our torso. Pelvis can be tilted anterior/posteriorly to varying degrees and so can the ribs be flared or tucked (can think of this as thoracic extension/flexion also). We brace most effectively when ribs and pelvis are in neutral (see vids below). For you that may mean cuing ribs down and pelvis tucked at the start.
When u lock yourself into a neutral position will probably feel abs and glutes coming on which is a good thing. Now that we’ve set neutral position we do the breathing tings. Like I said neutral spine enhances the brace/stability/torso stiffness you can achieve, because bio mechanics and shit, and it’s probably protective against injury.
Check the vids in this reply I made to another dude.
It’s mostly all there but there’s plenty of other resources if you want em. If you like long form lectur-y stuff:

Isa something I’m working on myself currently. I tend towards extension patterns myself in the squat because I’ve squat that way for a while until relatively recent. Contributed to a back injury I had last year
