more fuel-saving bull**** (lowered suspension)

claims lowering a Camaro an inch improved fuel consumption 13% !!!

I really doubt this, unless you drive around at twice the speed limit.
Besides, I have conflicting information in various forums that lowering
a road car (with irregular underbody) may increase turbulence.

I would agree that it probably has little effect on fuel consumption. But
isn't the point of HAVING a lowered Camaro to drive around at twice the speed
limit?

Depends a lot on the underbody, but yes. That's why those plastic guards
exist, to try and get laminar flow underneath.

Lowering the car reduces "frontal area". Car will get better fuel
economy... and have (yippee!) a higher top speed!

Stock 1971 Datsun 240Z... top speed 124 mph... fuel economy
under easy highway driving-- 28 mpg (imperial gallons).

Same car with only a change out to Mullholland short springs...
top speed increased to 132 mph (6.45%)... fuel economy
under easy highway driving went up to 31 mpg (imperial gallons) (10.71%).

Anything you can do to reduce aerodynamic drag will increase mpg and mph
for the same power. The higher the speed the more the aero effects the car.
Easy to see this by watching nascar. They add a couple strips of tape
and gain speed.

Does altering the aerodynamics make a big difference at normal street
speeds? That all depends on the vehicle. Most modern vehicles are pretty
slick from the start. Lowering might help, but it can cause a lot of
headaches as well.

I Agree with what Steve W. said.
