I know the aero package is supposed to zero rear lift, but what would happen if I only installed the front lip spoiler? I don't really like how the rear looks.

I ran mine like that for 3 months and the front felt a little more stable at high speeds (100+) didn't make the car unstable ever.

 

the front spoiler reduces drag. rear creates downforce. or so they say. there is also a 3rd peice on the underneith thats a bit elusive, only get it on track model, not part of aero package.

 

Well of all the aero peices, the front lip would likely make the biggest difference to handling caracteristics. Forcing more air over the top and around the car rather then underneath gives you much more stable handling carachteristics as high speed.

From what I understand the rear underside peices just clean up the airflow exiting the car and contribute to the .29 COD however aren't the single determining factor. Either way I've requested to look at the underside of my car on the hoist to actualy see the additional aero peices.

So to your question, yes, adding just the front lip spoiler would help. A splitter however would likely provide even more performance so you may want to consider saving your money and purchasing an aftermarket front lip and realize even more benefit although I'm not to sure on the cost of the OEM front lip spoiler.
