The Bus is probably awesome but excess camber can't be good on the others. Tires rubbing on fenders can't help r.r.

Okay, what the heck is RR? I know lower usually means better control, but that low seems extreme.

Look carefully at the sign, the car isn't modded, the occupants just ate too much!

Keep the tire camber under control and the tire inside the well. Lower is better for aerodynamics, but don't expect your "handling" to improve as suspension is designed to operate only within designed travel and angles. Exceed these and you will have less control than designed.

This, somewhat.

The effect of lowering on your suspension has a LOT to do with the geometry and type (Strut vs. double A-arm vs. straight axle, etc.) Cars with good geometry can be lowered a TON and still have very good handling (or better due to stiffer springs and lower CG).

But basically... lower = lower CdA, so its better for economy.

Tire to fender and suspention contact is just going to add more drag.
Wearing the tire on its outer most edge is the oppisite of economical.

My engineer friend raised his 2000 sunfire by about 2 inches when he replaced the worn out struts on all 4 wheels. He said the effect was with in the standard devaition for his fuel economy, didn't see any difference at speed on his scan gauge 2 and said you wouldn't know anything had changed other than the smoother ride.

Lowing a car to where you are going to be beaten by the road surface just to pick up some MPGs isnt worth it.

Ditto!

On the FreshAlloy.com site, one of the Lowered 2006 M35 lost control in a curve going 35-40mph when another car got in the way.
He was very honest about the fact the the 30 series tires and lowering kit probably played a significate roll in the car leaving the road and flipping.
