Aero side sills

[1st_Knight]

I just completed my installation of the Aero Sills, and I also took pictures of the area that needs to be slightly cut. I will try to post a pic of it tonight....

It's not much & you'll see the difference when you take the original sills off.
I don't have any other pictures.

After reading early posts about the slight modification that had to be made to properly install the Aero Sill, I too became somewhat curious and was wondering if the task at hand was going to be a big deal. However, and as mentioned by inTgr8r said, it's not much... The very small cutting of the sill was no big deal after all. Overall, it was quite easy.

Therefore, and to provide some clarification with the question of the so-called “required cutting”, here are some helpful pics…

First, please refer to the picture below, it is a close-up of the forward upper-inside portion of the Aero Sill as purchased. Within the red box you will notice that there is a small pre-existing cut out in the inside area.



In the second picture, I have crosshatched the area in red to indicate the small portion of the sill that had to be cut out. I utilized a simple hacksaw, then used an exacto knife & file to smooth out the surface. The cut area is approximately 1/8 inch wide by 1 inch long. Please notice that I started the cut at the point as indicated below, and I ended the cut at approximately ¼ of an inch from the tab closet to the front edge.



Also, and if it is of any consolation to anyone, the OEM Aero Sills, IMHO does definitely enhance the body of our Z’s, as a Victoria’s Secret push-up bra does for a woman’s cleavage…

Hope this helps & Good Luck....just be careful with the cutting, and verify the area to be cut out to the first protruding tab located on the black mounting rail within your own vehicle. Once you remove your old sill and inspect the area you will realize what has to be done.....

What I don't get is why it's not simply made that way. Even the original sill looked like it had been cut with an exacto knife when I did mine.

So where the top front corner of each sill meets the febder, it doesn't stick out a couple of millimeters? I installed mine without trimming the bit first, and looked, poked, and probed for a way to slot them in. Finally, I cut away the bit everyone is referencing, after noticing that the same area was crudely trimmed on the stock sills and checking Intgr8r's original post.

Maybe I'm just not seeing it so please let me know where it sticks out so I can trim it. It looks ok to me.

Nope, it's weird but your car looks fine. That's the first time I've heard someone didn't need to trim a bit to install them properly.

[NoCouT]

Well.. my kit was purchased 3 weeks ago and shipped from Germany.. maybe they updated it?

Possibly, but late in the game, isn't it? Production of the car ended months ago, after all...

That is interesting... because I had to trim mine also... Ah well, better late than never! Chuck I

NoCouT, since your Kit came from Germany did it come pre-painted? And did you order through a dealer?

Looks Great!

Thanks...

[NoCouT]

They come primed. You have to get it painted. I believe you can order them painted but they are BUX! You can order it from the dealer... tischers has it really cheap.

Maybe additional trimming isn't needed on non-M Zs. I needed to trim for proper fitment on my M roadster...

I went to a local dealership today and they want 2gs a side!
I was not expecting that, i will go check out what my normal dealer says about the price. 2gs a side cant be anywhere near right unless it's gold plated.

J_Factor, BMW's accessories page has the Side Trim priced at $285 a piece (US Dollars). Being that you are in Australia there may be a premium, but hopefully not that much. Anyway here is the info from the BMW page. Listed under "Aerodynamic Kit for Z4 Roadster".

Left Side Trim (PN: 51 71 0 150 781) $285.00
Right Side Trim (PN: 51 71 0 150 780) $285.00
