You need to run much higher pressure. The tires are rolling over too much.

Also cold pressure is not a relevant measure. The difference is huge if it's 40F or 90F ambient temp. You should set your tires' hot temp right after you come in. Street tires should run at least 40psi hot.

(You will notice that as you run harder and heat up you tires more, you will start with lower cold pressure.)

Re: feathering, your tires don't look too bad. All non-slicks (incl. unshaved RA1's) will feather a bit due to the hard braking and cornering.
