If the Rimac Nevera booklet asks for small screws you cannot find in any bag — the front-wheel-axle step (step 5), and the screws illustrated for the steering assembly — nothing is missing from your kit.
What happened: during development, those assemblies were redesigned to hold together without the screws, and the booklet was not updated to match — so it still shows the older version of the steps and asks for screws that were deliberately removed from the kit.
What to do: build the assembly as the step shows, just without the screws it lists — the parts are designed to hold without them — and carry on. The design change does not alter any later step.
If a different screw group seems short, that is another matter: the groups and how to tell them apart are covered in Which screw goes where when building the Rimac Nevera.
If you are not sure which case yours is, message us here, or email [email protected], with a photo of the booklet page and the screws you have, and we will confirm which case yours is.
