Tire advice? Hook with high low end TQ?

My e63 M6 should be done in about a month from Troy Jeup.

5.5l 13.2:1 CR gas/methanol. Race seats to drop about 100lbs in the middle of the car. Carbon fiber driveshaft drops some motor weight. BC coilovers.
I realize 19 inch wheels would be better but itís not a full race car I still like luxury and I got a pair of Vorsteiner VFF-103ís 20x9.5 et22 up Front 20x10.5 et 34 in the rear in near mint condition for interview dollars so Iím going to go with those.
The problem is what rear tires to get. Torque power band is 3300-7600 so Iím going to have a lot of low-end torque and problems hooking. Iím adding long tube headers to drop a little down low torque and gain it up top.
My previous M6 was just bolt ons and the fenders were rolled and I used 285/35/20 ToyoR888ís and they hooked amazing. They look perfect with spacers but the old fitment was Forgestar F14ís 20x9 et.18 fronts and 20x10.5 et.25 rears.
This time I need to go to 305ís. Iíd like 315ís but Troy said even with the fenders rolled 305ís is about as wide as I can go but Iím going to need a lower wall like a 25 or 30.
I assume I also have to go with a bigger wall up front like a 275/30 if I go with 25s in the rear or 275/35 upfront if I go with 30s in the rear but upfront isnít a problem because I donít need drag radials or Rís up there.
I live in Southern California it hardly ever rains. I dont track the car itís more of a weekend car but I want to hook up on the street.
Really my only option with the 25 is the 305/25/20 Toyo Proxes Tr1 but I donít know much about that tire and Iím not sure if itís going to hurt.
There are more options with a 30 wall and Iím debating between the Hoosier R7 305/30/20 or Nitto Nt05 305/30/20 but itís not the Nt05ĒrĒ itís just Nt05.
So I guess what Iím asking is what will be the best option between those two or the Toyo Tr1 with the 25 wall? Or if you happen to know of a better tire?
Thank you

Cup 2s bro. The best compromise in terms of grip, tread wear, usability in the rain, and price. Post some pictures of your car when it's finished! (With engine bay pics)
