Autocross tire selection advice for a lowly 2010 V6 auto car...

I still roll on the stock 20x10 - 20x11 because every time I am about to pull the trigger on a dedicated track 19" wheel/tire combo, something pops up that sucks away my "fun money"...
The only good tire I have found for the 20" are the Toyo R888R in 285 and 305.
I have heard mixed feedback about the R88Rs for our heavy cars as well.

I had to work with more "streetable" tire options.
My MPSS were a great "all-around" tire. I ran Nitto Invos for a few years which were "OK".
Not nearly as good as the MPSS but handled hot laps better then I expected.

What Joelster is saying is right. Stepping down to a 19" or 18" wheel that is at least 10-11" wide is the ticket.
More tire options available and you need as much cross-section as you can get for these heavy cars.

Just getting out and having fun in the car is most of it. Run what you got and see how you do!

Does the car push in corners with the staggered setup?

I have 285/35/20 all around and need new tires, but also added rear traction as I am making good power(close to 600whp). Wondering If going to an 11 inch rear and 305 will help or if it will not be compliant in corners?

It does push in the corners a little, but I can help it rotate with the throttle still.
I love the look of a big fat tire on the rears on the street, so that is the price I pay for wanting that look.

I am running 295/35R20 on the 10" wheels in front and 315/35R20 on the 11" wheels in the rear.
When the day finally comes where I get my dedicated track wheels/tires, I will be going with 19s with 305 tires at all 4 corners, like the Z/28.
