STAGE 86

 Return to the BUILD


“LaFerrari’s active aerodynamics involves the use of active diffusers to maximize performance and control depending on the driving conditions.”

As the Tail is attached to the Chassis in this stage, it is going to be a bit longer than usual.

The Active Diffusers

NOTE: I did these steps slightly out of order from the instructions with the idea that it would make a bit more sense.

Step 1

For this step, we need to retrieve the following parts from previous stages:

  • The Mobile Wing and Front Linkage from Stage 81
  • The Mobile Wing Bracket, Rear Spoiler Lever, and two Brackets from Stage 83
  • The two Safety Clips from the previous stage

Fit the eyelet of the Rear Spoiler Lever between the tabs of the Mobile Wing Bracket and secure it with one (1) Type P screw.

First, I recommend driving the Type P screw through the holes of the Bracket from this side. This will help make sure the screw will go through straight:

Next, note how the eyelet of the Lever is offset in relation to the arms. We will want this flat side to be facing the top side of the Mobile Wing:

Therefore, this is how the Bracket should be attached to the Lever (both of these parts are shown upside down in relation to their final position):

Knowing this, we can remove the Type P screw and reinstall it with the Lever in place, as shown:

Fit the Mobile Wing Bracket to this matching recess of the Mobile Wing orienting it as shown, and then secure it into place with one (1) Type F screw.

Do not overtighten this screw as it could damage the Bracket:

This is how our Mobile Wing assembly should look:

Then, fit the eyelets of the Front Linkage between the two outer sets of tabs of the Wing and secure it into place with two (2) Type P screws.

Again, I recommend first running the Type P screws through these tabs as shown so we can ensure the threads will be centered:

When aligning the Front Linkage to these tabs, it should be oriented as shown. The offset L-shaped tabs (circled below) should sit up like this:

Knowing this, we then can remove/replace the Type P screws to attach the Linkage to the Wing, as shown:

Finally, fit the slotted end of each Safety Clip over these flattened pins of the Front Linkage.

Each Safety Clip has this slotted hole at one end:

These slotted holes are designed to slide over the end of the L-shaped tabs of the Front Linkage, as shown:

Once fitted, the Clips should be able to rotate around the pin and not come off easily:

Repeat this process to install the second Safety Clip on the Front Linkage, as shown:

This is what our Mobile Wing assembly should look like now:

Step 2

Retrieve your Rear Chassis assembly from the previous stage. Lower the Mobile Wing assembly into the rear of the Chassis, as shown.

As you lower this Wing, the Safety Clips need to feed down through these openings of the Rear Frame Bracket:

The crossbar of the Front Linkage should end up in front of, and under the curved orange Electrical Cables, as shown. You may even want to temporarily remove these Cables to make this work easier. You will see my Cables come and go in the pictures on this page as I worked through the stage:

The large pins at either end of the Front Linkage will eventually come to rest on these ‘pads’ of the Rear Frame:

Fit the base of the Mobile Wing Lever to these matching posts of the Rear Chassis, as shown:

Secure this Lever base to the Chassis with two (2) Type D screws.

This is your friendly reminder to try using 3-in-One Oil on the threads of all screws going into metal parts:

Cover each end of the Front Linkage with the Brackets, orienting them as shown and aligning the screw holes.

You may find it easier to raise the Mobile Wing to its upper position to improve your access these areas:

Secure these Brackets to the Rear Frame with four (4) Type H screws – two on each side:

You now be able to easily raise the Mobile Wing

… and lower the Mobile Wing back into its stowed position:

Step 3

Retrieve your Tail assembly from the previous stage. Fit the Tail assembly to the back of the Rear Frame.

The instructions make this step seem simple, but it actually takes a bit of effort as a few things need to happen at about the same time:

  • The two rounded tabs of the Tail need to ‘pop’ over these mounts of the Rear Frame:

  • The Safety Clips need to pass through the rounded slots of the Diffusers at the bottom of the Tail

  • The Tailpipes need to pass through the matching Grille openings of the Tail:

  • On my model, I routed the LED Cable wiring from the Rear Lights over the top of the Wing Frames on each side:

  • This screw post on the bottom Diffuser needs to pass over this part of the transmission

  • The exhaust pipes need to clear this lip and screw mounting points inside the lower Diffuser:

When the Tail is fully seated, it should sit across the bottom of the car like this:

  • To keep this assembly from coming apart again, I read ahead in the build and used two (2) Type N screws to secure the Tail to the Frame:

If you removed the Electrical Cables during this step, you can reinstall them now:

Again, we can check the operation of the Mobile Wing by raising and lower it:

Step 4

Carefully turn the entire Rear Chassis assembly over. Slide the side pin of the Right Active Diffuser (marked ‘R’) through the eyelet of the exposed Safety Clip on this side of the car, orienting it as shown:

Next, rest the forward pins of the Active Diffuser in the matching slots of the main Diffuser assembly and fit the Right Active Diffuser Frame into place as shown, capturing those Diffuser pins:

Secure this Frame to the Diffuser with two (2) Type Y screws:

Step 5

In the same way, slide the side pin of the Left Active Diffuser (marked ‘L’) through the eyelet of the exposed Safety Clip on this opposite side of the car, orienting it as shown:

Again, rest the forward pins of the Active Diffuser in the matching slots of the main Diffuser assembly, fit the Left Active Diffuser Frame into place as shown, and secure it into place with two (2) Type Y screws:

Thoughts


If all went smoothly, we should be able to raise the Wing and it will extend the lower Active Diffusers. I have to admit, this might have been the most troublesome step of the build so far. It did not feel like the wing wanted to easily slide into place and there were many things that had to happen around the same time to get it all to work. But, once it is attached, it does look fantastic!
