Well kids, krampus came early for me this year and brought me a sweet rear diffuser!
Unfortunately I didn’t get around to finishing the writeup until now. Sorry about that.
So first things first….Order one.
Download the assembly instructions and read ’em over.
Next, assemble it. It’s REALLY straightforward, only goes together the one way. Don’t forget the loctite!
Now bring over a friend to help, and preferably a second floor jack.
Safely jack up your car, like so:
If your car is like mine, you may find that you have some tabs sticking down from the ‘bathtub’ of the trunk. Since that is where these attach, I went ahead and just hammered mine flat. Not sure exactly what their purpose is intended for, but there’s nothing but sheetmetal around, so it seems okay.
Once you have the rear end of the care SAFELY in the air, slide your other jack into position with a nice blanket or something over it to protect your diffuser.
Gently jack the diffuser up while holding it to stabilize it, until you get it about in place.
Clearly mark the locations you intend to drill, and use the 3gcustomz install guide to ensure your placement is correct (e.g. Centered). Also ensure that the fins on the diffuser are true to the direction of the car, you don’t want those pointing off to one side or another.
Drill your marked holes out and insert the spacers where needed (this will depend on the year of your vehicle and can be referenced against the 3gcustomz install guide.
Work with your friend to get the bolts mounted up in place, and torqued down as needed.
Use your friend as a prop for a cool photo, like so:
Then take lots of pictures showing how cool everything is, and go for a test drive!
