I agree as well, i don't like the look of the stock spoiler, either get the R3 one, Evo-R, or JDM/Euro lip spoiler, much cleaner look in my opinion.

 

Stock spoiler.

The trunk looks far too naked without it.

 

Go for Mazdaspeed wing, the best
Especially you have front lip

 

Get a lip!

-Knight sports lip
-R-magic lip
-RE Carbon trunk
-RE lip
-Vertex lip

etc.

 

Without. The stock wing and others do nothing but add weight. If you're going to put something on get a lip spoiler.

If you look at other performance sport coupes, the most they come with are lip spoilers ala the M3.

 

I dont think so....the wings give down force, mazdaspeed has the most down force beside the GT wings, the lip actually do nothing at all
a good carbon fiber GT wing gives more than 500 pounds down force

Speedsource RX-8 : An adjustable rear wing and rear under-spoiler create downforce in the tail.

The wings help getting less oversteer

 

because you have a far protruding front lip, it gives the lines of your car a diagonal slant from your trunk lid to your front bumper lip. It looks good w/o but if you do decide to get a spoiler, get a spoiler that protrudes back past your trunk lid rather than up.

hope this helps
