why do weak torsion bars improve launch?
..no matter which bars are installed they are always trying to raise the front.
 
Because to get the ride height correct with the weaker bars, you have to put more turns in them. This preloads them more than the heavier bar.That gives you more stored energy to transfer weight with.
 
Technically it takes the same amount of "stored energy" (elastic potential energy) to hold the front end off the ground a given amount regardless of wheel rate (spring constant "k" in Hooke's Law). It's a function of front end weight.

In a launch situation a softer set of bars may have more (angular) preload remaining when the UCA hits the rebound stops, where a set of stiffer bars may be completely relaxed before the UCA hits the stop. So the softer bars may not actually release all of there potential energy.

Smaller bars are physically lighter which helps. A set of 90/10 drag racing front shocks will help let the front rise on launch.

You speak technically.........we'll speak mechanically.
