Re: Have you ever wondered?
OK, so my dad talks about his '41 coupe he had in the mid-50's and it was adorned with what he refers to as "flip-flop hubcaps". He also talks about the rear suspension being dropped down low with skirts. He described it as having the car's nose pointed up in the air. I have heard others refer to this as a "speed boat stance" and it just looks cool on cars from the period, so I suspect that lowering the rear end was just plain easy to do and made a fairly dramatic change in stance, so it became popular.
