I'm coming into this a bit late with all the responses. I think your camber is generally ok. I run -4F/-2.5R, so you're at least in the ballpark. I also run 6k springs all around vs your 7k, but they're both square.

I was dialing mine in earlier this season and found more (stiffer) settings in the rear REALLY made a big difference. I was starting out using the recommended 10 clicks from stiff front and 8 clicks from stiff rear and the car didn't want to turn. Very understeery and hard to drive.

I did a test and tune playing with all the settings trying equal, stiffer, softer, and variations front to rear. I settled in that softer in the front and stiffer rear was the ticket. I'd personally try that before swapping out parts just yet.

I also went back to zero toe all around. With those settings it didn't need to toe in rear some people run.

In all your mods and settings, that's the glaring issue to me. Might want to try it before trying to swap in new springs. I think 7/9k springs are becoming more and more acceptable for autox due to the motion ratio in the rear. I feel like playing with the settings is a bit of a bandaid, but it works just fine for me.
