Reference would be Hoosier R7 265/35/19 front, 295/30/19 rear. Best Laptime NYST 1:35.7. Cost $1521 a set with a coupon from trackdaytire.
For the majority of the trackdays I will be experimenting with tires on number of levels and using Aim, I am going to monitor performance and wear.
I am trying to focus on spending $200 per tire. Using eBay and used tires combination.
For alignment I am going to see what Front max negative camber I can get. Rears are on -2.0 and for now I'll stay on -2.0

Why? What issue are you trying to solve? More camber results in less braking force available. The rear of the E90 doesn’t need too much camber to work well.
I think the problem statement you’re trying to solve is: “what is the optimal camber at the rear of my car?” However, randomly throwing tires at the rear will result in random results. Each tire (e.g., R7) has a sweet spot for camber. Throwing tires, including mismatched compounds, on the car will lead to indeterminate results and likely, frustration.
Now, if your goal is to turn gas into noise; carry on.
