Interesting point, The Porsche 928 looks to me like
its bumper directs alot of the windflow underneath the
car, much like our high riding westys/syncros do.
Underneath most cars, its not smooth and wind
resistance will be greater the higher up your car
rides. So, i think Installing lower coils along with a
quick release spoiler under the bumper......(a big
one.....for long trips only) would be the way to go.
But if i lower my westy i wont get that nice floaty
ride that i love so much.
