Front and Rear Spoiler and diffuser installation
I just installed the factory Track model front and rear spoiler kit on my car and found it to be a great project. The supplied instructions are excellent and the paint match for my Redline car perfect.
I also installed the Track model's under car air diffusers, these are not mentioned in the spoiler kit literature but are part of the Track's hardware. The diffuser part numbers are 748A0-CD800 and 748A0-CD810. These mount to the left and right of the muffler, the mounting studs and threaded holes are there ready to go. You will also need a clip part number 01553-09321, 2 bolts part number 08146-6125H and two 6 mm nuts with washers to install.

I will try to attach pictures when I get time to figure out how this forum posts pics, I am new here.
The diffusers cost around $70 with attaching hardware. They are complex plastic baffels that fill in space at the left and right of the muffler. If you did not have a car without them to compare you might not even notice them.
In the Z literature I note it says zero lift in the front which apparently applies to all models and zero lift in the rear with the diffusers and spoiler of the track. The inference has to be made there is lift in the rear without the diffusers and spoiler. The literature also claims a Cd of 0.3 for non-Track models and 0.29 for Track models.
I installed the spoilers myself, but I have worked on cars all my life and have a large tool collection, compressed air etc., so I am comfortable with such projects.
The drilling requires a careful placement of a template supplied that indicates where the holes must be drilled. I spent a lot of time measuring with dividers to make sure the holes were centered. The motto is: "measure twice, cut once". The drilling requires a 13/16 hole saw, 1/8, 1/4 and 3/8 drills, which are used in succession to get the final 13/16 and 3/8 holes for the install. I always use new drilling tools for drilling in finished surfaces and used them this time as well. Also nice to have a apring loaded automatic center punch for marking the holes. Once holes are drilled, the rest is easy.

I noticed that courtesy doesn't have the rear diffusiors, just the one for the front, i guess this is something you would have to go through a dealership for

cupcar- just out of curiosity, you mentioned paint match perfect. Did Courtesy send them to you painted?
Also, posting pics is easy, under "attach file" below the posting box, click browse, find the pics on your hard drive, and upload.
I am thinking about an aftermarket front spoiler, i.e. C-West, I wonder if it has the same aero properties as the oem front spoiler? It's a fairly simple design.

i dont think the aero spoiler that cupcar is talking about is not the same thing you are thinking about.
what cup car has and what others who have the aero package is
a little 2" black strip that goes under the bumper you cant even see it unless looking under the car.
i like mine cause if i scrap underneath my bumper nose it will take some of the abuse
if you want a lip nismo next month is coming out with one more like a body kit
this is all the front spoiler is

And here is the left diffuser.
I think it would be difficult to make your own, and not worth the time given what they cost. The pictures don't show much of the diffusers, particularly the left shown below. The left side extends about 6 inches upward into the wheel well out of the picture.
I too was surprised that the rear spoiler came painted and ready to go, that is one of the things that made the project fun!!
