Good set of questions AmmarYasirA. If the splitter is flat and isn’t specifically designed around the tyre I don’t see any reason why you can’t do it. You will need various hard points to the chassis to ensure rigidity at minimum and maximum overhang. My understanding is that the F82 GTS splitter is relatively short.

I think it would be difficult to incorporate this feature on the Z4M and keep the width of the current splitter. This is mostly due to the relatively short bumper especially in front of the tyre.

Being able to change the aero balance has been on my mind. I have got a few ideas but that is all they are at the moment.

I have done a little bit more work on the Canards. I have created a bi-plane version with a smaller secondary item that sits higher. There is quite a bit less space here so I had to reduce the chord.

The design is starting to flow quite nicely with the sharp edges matching the rest of the car and the endplate detail returning on the splitter. The additional element provides extra downforce due to a local suction and pressurisation increase. It also yields a further improvement in downstream flow management by improving the energy near the bottom of the tyre and a little bit more adjacent to the wheel. The illustration below shows the flow energy distribution with no canard on the left, one canard in the middle and the bi-plane two canard setup on the right. High energy in red and low energy in blue.

Ever since I started posting here I have had a lot of interest. So first of all thanks very much for all the replies and private messages it is much appreciated. The design of the canards are getting more and more finalised. Based on the amount of positive feedback and interest I am considering selling these to our Z4 community!

If you would be interested and haven’t already let me know could you please reply or send me a private message? If you would like to see tweaks to the design or have any recommendations then please get involved as well! The next step is to increase the size and width.

Thanks MYWAYNY. One of the next steps is to scan the various mating and mounting areas around the car. I am in contact with various companies so hopefully a bit more progress on the production front in the next few weeks.

Love to see these when they are complete, definitely in for a set of the canards.

Cheers M-Cast and 3GFX! I should be scanning the car soon. Hopefully we can start to pick up some momentum!

That is exactly what I need to finish up this beast. Have you ever looked at doing spats on the front fender wheels?

Looking good M-Cast! I agree a set of Canards would complete the front

I have personally found the spats to be less efficient than a good canard setup, especially if the front diffuser isn't that aggressive. It is something I might consider for the future though!

After approximately 4 days of scanning the Z4MC we have got the data we need. The blue laser scanning allowed us to capture hundreds of millions of data points all over the car. This is not just for the Canards and Splitter but also for other future projects I have in mind.

Here a little sneak peak of the setup.

The scans allow us to reverse engineer hard points, mating faces and establish no-go zones. What is very encouraging is that the photogrammetry is already very accurate in the easy to reach areas. The illustration below shows a partial capture of the underneath.

The next step is to reverse engineer the local surfaces and start finalising the Canard Design.

It appears there is a lot of interest in these side covers across the owners. I am surprised no-one has picked this up yet! For a copy/replica you could create some moulds from the original part. The 3D scanning and reverse engineering tends to become more interesting when creating new parts and functionality.

Apologies for the delays in posting an update, a few weeks of holiday does that to you. Things are going well with the external canard surfaces finalised and ready to go.

We are now in contact with a variety of suppliers trying to pick the best for not only these parts but for any other projects in the future. We are working on a nice mounting method that would aerodynamically seal it to the bumper and leave no fixings exposed.

Good progress is being made on the splitter as well with many more CFD runs performed. The reverse engineering of the bumper mounting faces is complete as well as the main external geometry. There will be more information posted on this later!

Hopefully we will have more information soon with regards to the production stage of the canards. Let us know what you think!

Really liking how this is coming along!

If you went bigger on the splitter would it increase down force?

This looks very nice and appreciate you making new parts for the community!

Maybe I am alone with this but I would be interested in seeing something more track-focused, similar to what BW offers. An off-the-rack large chassis-mounted splitter with aggressive dive planes is not currently offered for the Z4/Z4M.
