Car Bluetooth Device Specification Example for Passenger Cars: Racing Spec
Car Bluetooth Device Specification Example for Passenger Cars: Racing Spec
This is a worked specification for car bluetooth device in a racing spec programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The racing spec version exists because the duty cycle on passenger cars is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually warranty claims traced back to a single lot.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Silicone, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.

Processes involved
- laser cutting
- injection moulding
- gravity casting
- assembly line testing
- shot blasting
- rubber vulcanisation
Where this example applies
Programmes that run racing spec most often specify this build for passenger cars. Related applications include workshop replacements, trailer axles, dealership service, passenger cars, three-wheelers.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
What testing is included?
Standard lots ship with dimensional and hardness reports. ECE R90 documentation is issued with the shipment when your market requires it.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
