I've ordered a G with Aero Kit 4-piece, but a same G is currently available with Aero Package + Aero Kit 3-piece. Exactly what is the difference between these two configs and why do you guys think one is better than the other?

Aero Kit with Spoiler 4-piece = $1190

or

Aero Kit without Spoiler 3-piece + Aero Package = $1150

 

The Aero Package + 3-piece kit would be the better way to go between the two.

In a nutshell, the only difference between the 3-piece and the 4-piece is the rear spoiler. If you order the Aero Package which already comes with rear spoiler and includes the underbody air diffusers for the so-called zero-lift kit, you dont need an Aero Kit w/ a rear spoiler as well.... so they offer a kit for a lower price that does not include a duplicate rear spoiler.

Hope that makes sense.

basically if you dont like the look of the spoiler but still want that .1 diff in downspeed or was it .01? u can get the aero kit... plus the aero kit is alot cheaper but thats just my 2cents

 

Thanks for the reply guys. But what are the parts difference?

Aero Package + Aero Kit 3-piece =
*Rear spoiler
*Rear underbody air diffusers
*Front bumper chin spoiler
*Aero body splash guards

Aero kit 4-piece =
*Rear spoiler
*2 underbody diffusers
*2 under covers
*Front bumper chin spoiler
*Aero body splash guards

Is "Rear underbody air diffusers" the same as "2 under body diffusers"? And what is "2 under covers"?
