A torque stick may well limit the output torque and a truck suspension would work similarly, but ONLY if you get the rear wheels off the ground. Then and only then will you no longer be able to apply a higher torque...All the suspension of the truck does is cause you to have to travel the wrench handle further to build the needed torque.
Yep. Unless you're deforming (twisting) the torque stick so much that the wrench won't click. If the wrench clicks, the torque is right. The "springiness" of torque sticks can make it harder to get the torque precisely - same as with a beam type torque wrench - but the solution is just a matter of applying force smoothly.
Extensions are another matter. In relation to torque wrenches, common socket extensions (i.e. axial ones, like torque sticks) don't change anything. A "crow's foot" type extension does make a difference.
