Shocks do help 'lift' the car if they're damping is both rebound & bounce, which std shocks are. Front Koni Sport adjustables, for example, are rebound only so don't 'lift' the car.
I think that's incorrect, frankly...
What is "bounce"?
Did you mean "compression"?
"Rebound", of course, is the upward stroke or return stroke after compression (obviously..). Rebound does not lift the car, it is literally the spring returning to equilibrium after compression. The damper is there to prevent repetitive oscillation - either way.
Did you know the car is also a "mass damper" to be factored in? No, I thought not...
What you (incorrectly) imagine as significantly lifting the car, is really just the pressurised gas put in there to prevent cavitation in the damping oil.
Also, Koni adjustable dampers will
compression damping, as most dampers do - because both suspension strokes need to be controlled to one extent or other.
What they lack is a dedicated external adjuster like the rebound aspect does.
As usual, there will be no charge for this information...
