I runn the same tires as you, 275 x 40 Nitto drag radials. When trying to get a good launch I drop the pressure all the way down to 12 psi. I know it doesn't sound like much but it doesn't want to travel or sway at the 1/4 mark. They still feel very responsive. It will also knock a lot of your hop out, not all of it but most. AND notice how much better they hook up!
