Downpipe for Toyota Corolla: Carbon Fibre Composite
This downpipe for the Toyota Corolla is specified around carbon fibre composite, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is lead time that slipped twice before bulk started, or premature wear on the first batch. Both are specification problems, and both are preventable.
