Rear Diffuser..help

I understand its purpose for aerodynamics... but is it actually worth it?

well, what are aerodynamics worth to you? They do serve a purpose just like all of the other aerodynamic parts made for a race car, but i think a lot of people will never push their car that hard to even put their fancy front lips and diffusers to use.

aw... but I like my fancy STi Limited knock-off lip

Subieboo204, are you referring to the roof-mounted mini spoiler that comes on the older STis or the plastic under diffuser that sits behind the rear differential on the older STis? I'd love to get a rear under diffuser for my WRX. I just like the way it looks, although I think it might have to be trimmed if you upgrade your stock exhaust to an angled-exit big momma fart can or maybe if you get a larger aftermarket rear sway bar. I'm not terribly crazy about the looks of the roof-mounted piece though.

midniteblack is correct. For a daily driven street car, both of them are mostly about looks.

no hate here, i have one too! I'm glad i have the flimsy knock off or else it would have broke a long time ago if it was authentic.

Haha yeah, I've definitely scraped the bottom of mine a couple of times and my car's not even lowered, but the looks are killer. When I first installed it with the 6 or so screws that were provided, I saw that there were tiny little gaps between the bumper and lip where the plastic sort of wrinkled from the pressure between the screws. So... I secured it with about 40 extra screws and bolts all the way across and now the gaps are gone. That thing's not going anywhere. I think I might leave the lip on during the winter too. I was also tempted to run a line of clear or black caulk (or something similar) between the bottom of the car bumper and the top of the lip just to seal everything up completely, but that might not look so good because of the glossy paint being next to the flat finish of the lip and it would make things difficult if I ever do decide to take the lip off.

i have an 06-07 sti rear diffuser with the cusco subframe brace and i don't know if it very functional but it does suck up the dust on the road. i did have to cut it to fit my huge turboxs rfl axle back but my perrin 22mm sway bar clears with no problem im happy with it

Do you upgraded sway bar mounts? From my understanding, it's those that the Cusco bar won't clear.

My whiteline sway bars clears my rear diffuser but my invidia exhaust rubbed on the front left of the diffuser and it melted a little bit off of it.

There is no way of noticing it unless you get underneath the car.

rollin on 17's now and they're dirty
