Got this spoiler not too long ago...LUV IT!!! perfect for the TSX IMHO. Lot's of compliments.
Never liked the m3 lip cuz u could easily see the tape underneath the lip(tacky) & the oem wing is too big.
You cannot go wrong with the FLP spoiler.

I came from the ebay M3 style lip spoiler. I love how this spoiler looks and thus the reason why I switched out.

I think the price is just a tad high because of the off brand. But I think the fitment and the craftsmanship is excellent and thus making the price not so intimidating.

[This customer forgot to write a review but they were probably going to say something like "super awesome and fits amazing!"]

Not wanting a generic eBay "M3" trunk spoiler, we developed this Fastline Performance trunk spoiler to truly compliment the lines of the TSX. The shape of the car is made up of clean, flat panels, but the slight curves convey a sense of sportiness that is dulled by the typical Honda conservative wheel/tire package. Still, the Fastline spoiler dresses up the rear of the TSX in a way that makes it look more sporty without being immature or tacked-on. The fitment is amazing, and the finish it top-notch. I can't comment on aero improvement but I would venture a slight aerodynamic gain would be seen at high speed, albeit not necessarily felt. I'm very proud of this part! Great compliment to any TSX!
