Cutting apart the rear bumper

[Snowblind]

I think the Honda Civic teenaged crowd does the same thing.

Anyhow, here is the Tom's diffuser, that required cutting the factory one away. I replaced the oem tail light with mesh, and relocated the reverse lights to my backup camera.

It's my daily driver....see's public every day. You're free to laugh... but it looks better and is functional compared to stock when using Y style merge collector aftermarket mufflers. There is a difference in high speed stability like I said with that section removed... plus once I get the LED reverse light I have where I want it so I can get rid of the stock one and rework the exhaust to a twin center exit then I will be making a real, functional diffusor for even better high speed stability...

This is just a very rough representation of the planned diffusor design...think of it as a double-tunnel hull design, where left and right hand sections have a steeper rise than the center section under the exhaust:



Final design depends on how I can actually get the exhaust worked out. Will probably go with smaller tips as that are oriented more like a 911 GT3-RSR racecar as well...

That's because of your aftermarket exhaust. The stock muffler works in conjunction with our rear bumper for better air flow. When you replace the stock muffler with an aftermarket that isn't 1 big muffler like the stock one, you'll get that.

Masking tape to protect the paint.
Cutting tool of choice.
Take your time.
Cut less than you need to, you can always go back and sand/file it down.

im really really considering this, and yes a diffuser from driveway maybe sometime later but i like the way it looks without just throw in a new pair of control arms, a brace and some coils and the exhaust would really accent the car. i am just trying to figure out how i would mount the reverse light until i get the intec tails which have the integrated in them. It being texas i dont see the issue will having it untill i get the lights but dont wanna take a chance.

If you want the perfect reverse light solution - go with the Diode Dynamics Tail-as-Turn+backup module and add in the optional XP80 reverse light LEDs....I was going to go the custom route, but once Diode Dynamics came out with this kit it was a much better solution...love it.



Very pleased with actually being able to see while backing up.... MUCH better than stock.

Still loving the fake diffusor being off the bumper...

will i still be able to use this as i have OEM smoked taillights?

Probably wont't be that effective with smoked tail lights, depends on how dark the taillights are... but mechanically no reason you couldn't use the kit.

Okay, instead of making another thread, I decided to Necro this one.

Has anyone reattached the bumper faux diffuser thing? I have a Black FRS with a complete bumper and a White BRZ with a cut bumper. I need the cut bumper on the FRS and the uncut bumper on the BRZ, but to do that, I would have to repaint at least one of them, if not both (one is a DD and one is a track car). But then I had the genius idea, what if I cut the Black bumper's faux diffuser and reattached it to the white bumper?

I figure a strong enough glue would be able to hold it on pretty well? Anyone ever try?
