If you launch on the street and the front tires have any weight left on them, you are not getting all the traction possible. But the goal isn't just to jerk the front tires off the ground, you want a smooth transition. Super loose front settings need to be accompanied with the right front spring. I generally want my front spring to un-load at about the same time that the suspension tops out, to minimizes any upset that the chassis might see at that point. A super soft spring that has to be compressed to be installed is not what you want.

With lots of front travel, it's important to do all you can to minimize bumpsteer.
