LEGO Technic 42143 Ferrari Daytona SP3 – instructions errors and fixes

Updated 09/01/2022

The LEGO Technic 42143 Ferrari Daytona SP3 is a great 1:8 scale supercar set, you can check my detailed building reviews here. Unfortunately the building instructions were released originally with several errors, I created this blog post to list what was found by myself and the community, and an indication whether they were corrected in the digital version or not.

The manual received a bigger update at the end of August 2022, the major issues are now fixed, as previously I strongly suggest to use the digital version of the manual.

You can see all the previously found issues listed below, with the indication whether it is fixed now in the latest digital version of the instructions or not.

Here’s the video about all the changes:

Step 88 (fixed)

In the paper manual the orientation of the 2 orange wave selectors and the green 2L beam relative to each other was incorrect, more details about this in my video. In the updated version the 2 orange wave selectors are rotated, but their position was not updated in the previous or following steps so you need to pay extra attention. They should look exactly like this when you add the green 2L beam:

Step 104 (fixed)

The part usage callout on top was incorrect, you have to use the part at the bottom and not the one on the top, the green checkmark and the red X was swapped.

Step 219 (not fixed yet)

This is not really an error, but easy to misunderstand. The assembly image shows the light bluish grey bush in the middle of the axle, but when you push the axle in place the bush has to be closer to the end that goes in the orange connector

Step 240 (not fixed yet)

A minor error, if the knob gear is in this position forming an X then the axle cannot be inserted in this position forming a +. Both the axle and the knob gear will have the + orientation when inserted in place.

Step 255 (not fixed yet)

There’s an L beam with blue and black pins added at step 250, their position is correct. At step 255 the position of the black pin is shown incorrectly, it should be in the hole closer to the horizontal beam as it was shown correctly in the previous steps:

Step 1115 & 1127 (fixed)

There are 2 black small panel fairings (#21 and #22) that you will find in the box and also in the inventory, but they are not used in the paper instructions:

They are now added in the following steps:

Step 1122 (fixed)

There was an error in this step, compared to step 1110 the sub-assembly was not mirrored properly, now it is fixed:

Step 1267 (not fixed yet)

The 1×2 bricks holding the L Technic beam cannot be attached in this exact position to the plate, they have to be shifted half stud towards the upper edge:

  2. The wrong part was included in the packet for step 384. 6293391 is needed and 4543489 was included. I did find the right part in another packet. I hope this won’t cause problems as I continue with assembly.

  3. 1/8 scale? Wow!

  4. And 42123 is McLaren Senna GTR

  5. Step 241 also had an error. The knob gears need to be in a X position or you can’t put the piece all the way down. The position change you mentioned in step 240 also makes this work…. otherwise these pieces would not fit between the other 2 knob gears.

  6. I was building the ferrari before, and passed step 88 without noticing. I am now later in the build. Will it still function or will I have to take it apart to make the gears shift?

    • Gear shifting should work, but not in the correct order. Honestly I would not bother going back, as the gear differences are hardly noticeable anyway.

  7. I have made it to step 88 and one of the orange wave selectors does not continue to spin and stops at certain points both directions, is this supposed to happen because its slightly worrying
