More front camber will reduce understeer as well. You are clearly not using the whole tire, pretty simple solution imho.

Even with a 6k spring and swaybar approx ~20mm solid full stiff I need -4 degrees to use most of the tire. I found the car decently balanced at -3 up front and -1.5 rear camber but everything else stock, that might work out based on just having the sti springs and alignment, you'll still get outer edge wear though, idk, you either add the grip and stiffness to the front or reduce grip from the rear to balance the car, I know which one felt faster to me.


You're not the first to avoid a stiffer front bar because 'that makes understeer' but it just plain works on this chassis, and you won't be the last to see that if you decide to do it.
Eibach 25.4mm or Whiteline 22mm might be a bit much unless you're playing with aero and slicks but on full soft they'll probably be good with the sti springs, perrin/whiteline 20mm bar would be my suggestion, maybe the perrin 22mm or Megan 25.4 if you plan on stiffening the springs and really going after the 200TW one lap hero TT class.
