Bodykits are rice its a pointless mod.. No one will ever see the need for such aerodynamics and the body kits for the alero if anything are less aerodynamic than factory. The only ok external mods are lowering it and possible a Razzi Wing but thats even pushing it.
Lower it and call it a day.
Who cares if its a V6 if it had a 3 cyl Geo Metro engine it still wouldn't justify the need for a body kit.
I do like your car though man, I would take off the center caps on your wheels though it looks so much cleaner, and leave it how it is! Your car looks great already man. Don't ruin it with a body kit
