That's correct, however, the shock absorber is designed to work within a range, as the manufacturer has designed the kit to be used at various ride heights. Standard shocks off a standard car, were designed as cheaply as possible, to do the job they were designed for.
My dumbass mate has lowered his Mk2 golf on standard shocks, by almost 100mm, and it's easily the worst handling car i've driven in some time.
