Tire temps other than on a skidpad are largely misleading. -2 rear sounds too high with only 2.2 front. Delta front-rear typically optimal on WRXs is about 1 degree less in the rear.

On the WRX, front sways are largely about fixing a roll-camber issue especially when lowered which you are. Yes, they transfer weight, but keeping the front flat is more important, and will likely keep that wheel down enough to keep applying some power.

The problem with most 1 way shocks like the AGX is that bump and rebound are tied together. Higher rebound keeps the spring from putting the tire back on the ground in transitional movement which is common in autocross, especially all the Z turns we had this weekend. On smooth surfaces like Stead, you can tolerate more bump, but not the rebound that often comes with it.

Font bars are proven to improve Impreza handling by minimizing the roll-camber issue. I would start there before replacing shocks.
