OEM diffuser question - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

brotha · 05-13-2015, 12:43 PM

Hi all! New here, I don't own an FR-S or a BRZ but I was curious to know if the stock diffuser was removable from your rear bumper or is it all one piece? I also wanted to know some of the dimensions of the diffuser. I marked the measurements I need in the picture below. I need the height, width of the top and width of the bottom.

Reason why I'm asking is because I want to try to retrofit the diffuser from the FR-S / BRZ onto my 2014 Toyota Corolla. Both cars are the same width (I know this has nothing to do with the size of the diffuser) But my Corolla has this piece of fake carbon fiber plastic that looks like it'd be the same width as your diffuser. If this is true then I would love to try to retrofit the diffuser onto my car. Thanks!

Picture of that fake carbon plastic on the Corolla I mentioned:

Ah ok, so the aftermarket ones are just covers that go over that part of the bumper?

correct.

Also, people running the rocket bunny kits cut this part off...someone should have one laying around.

With that said, you pull this off and the corolla will really be indistinguishable from a wrx.

Haha. Definitely gives me motivation to do this. I'm kind of nervous to trim and cut stuff to make it fit as I don't have money to go and replace the bumper on my Corolla if I were to mess up multiple times. I don't have much experience in doing these kind of custom mods so hopefully I can pull this off on the first try.

Anyway.. Anyone with the Rocket Bunny Kit have this part of the bumper cut off and laying around? I'd love to get my hands on it and experiment. I feel like the depth of the diffuser may give me trouble but I'll figure it out.
