I think it would allow the contact patch a better chance but I also just think you have too much rear grip. Next track event try running 44psi in the rear and staying at or around 40 in the front. It's a work around no doubt. 2" of wheel offset is going to be hard to deal with.
You could buy my 19x9.5/10's 3pc forged wheels with 275/285's
. I'll make ya a sweet deal!
