While on those tires, I installed camber plates which made a world of difference and completely eliminated the understeer.

I'm currently using a square wheel and tire set for the track which is very neutral at the limit. To achieve this, I have -2.5° of camber in the front and-1.8° of camber in the rear. With my stock wheels on the car, which currently have the PS4S on them, there is still a tendency to understeer very slightly at the limit, which is much safer for every day use.
My stock car does not understeer as you have described with the staggered set up.

The rest of your most is however fairly clear. If I want to use the ps4s I have to dial in -2.5 camber to the front.

Is there another tire available on the market that will perform like stock?
With all due respect, you have not found the limit of the cars capability if you have not found understeer on a stock suspension with staggered set up. Changing tires will not change the fact of the car is set up to understeer from the factory, mainly a product of having way too little camber in the front. Changing from one brand of tire to another is not going to drastically change the balance of grip between the front and the rear. Going to a square set up will eliminate some understeer, and changing alignment settings will certainly help, but if you ever autocross the car or go to a track where you truly are driving at the limit of grip, the understeer on this car is very frustrating.
