SuperStock spring tips.

I see what you're saying now. Thanks. The diagram doesn't show how that works but I can see how the arrows were conveying the general point you're making. The least lift needed to get the job done will certainly be the best. If none is actually needed, great.

To show how much (or little) lift will be generated, you need to find a diagram that shows torque, force and mass working through the link arm (or spring half), axle, etc. The result will then show the force down on the tire and this determines the amount of forward force a given tire can generate at the contact patch. If the torque arm created by the mass of the body and cg distance is greater than the torque from the tire (generated by the engine) resisisted by the axle and linkage/spring half then there will be no lift.
