YEP ! And to add to it....
Porsche, BMW and Mercedes have done this for over 30 years, especially in their low gas, twin tube use. They design in TONS of droop travel but little bump travel and instead use the progressive bump rubber to pick up where the spring left off. For an OEM car this works well. LArge sways, progressive bump rubber and tons of droop means a LARGE pothole doesnt disrupt the car(or the occupants).
Take that same car and lower it?
....and NOW a nice mid corner bump turns into a mid corner DITCH/ JERSEY BARRIER/ CAR NEXT TO YOU fender !
