Next step...
I think the Suspension is one of the trickiest areas of the build...
the Suspension parts are small and need to be folded and attached correctly.
The wheels and fenders are attached to the chassis using A-frame "control arm" pairs.
The paper model parts combine the upper and lower control arms into one assembly.
We'll refer to the pair of control arms as the "control arms".
Make sure not to mix up the front and rear "control arms".
And remember which side is up. (The glue tab attaches to the underside panel of each control arm assembly)
Each control arm is scored to fold at four lines.
Once again, its important to be precise with your scoring and folding.
...
Note the angled lines (on the model sheet) next to each pair of control arms.
This line is a profile of the chassis/control arm shape, showing you the downward control arm angles.
...
Cut out one of the control arms.
You should use a knife and a straight edge to cut out the part precisely.
...
Now fold the part into the correct shape and glue the underside panel using the glue tab.
The overall shape is not a box...but more of a parallelogram. (angled box).
This shape is important to create the downward angle of the control arms.
The downward angled control arms will raise the vehicle up, giving it "ground clearance".
...
The control arms attach to the chassis at the marked locations.
They just glue flat to the sides of the box rails.
There are also circle locators at the mounting locations...line those up...
to make sure you don't mix up the right and left control arms.
The control arms will hang a little below the box rails...thats okay.
Just flush up the top edges.
...
Heres a view across the front showing the downward angle of the control arms.
It needs to be even side to side...thats most important.
I think the intended design (as per the line diagram) is a bit excessive.
But the vehicle does need ground clearance.
So, angle those control arms down as much as possible.
...
And, a full view of the chassis...from the topside...with all control arms installed.

Another view of the completed chassis from the underside.
