When I’ve tried -2.2 in the rear, I couldn’t get the backend to hook up as good. But, when we’re talking tenths of degrees, track layout, conditions, suspension setup, and driving style will all impact those settings.

After running thru tons of 18 & 19” tires on my M2, I’m landing on 265/35 & 305/30/19 71R as the best performance bang for the buck I can find at the moment. Hopefully we get more options as 19” track tires get more popular.
That's great advice on your staggered setup. I've started to pester BFG to make some R1 & R1s in 19" sizes we can use. The R1 is my all time favorite r compound DOT tire.

BTW true slicks are even more difficult to drive on vs DOT R compounds. They all have very square sidewalls and have very small slip angles. User beware. I ran some YOKO's several years back...Went right back to DOT R's after realizing they aren't worth the hassle and quick wear for only marginally faster lap times.
