Transmission suspensionStructuralSafety 7 · Structural
Safety-critical part. This sits at level 7 (Structural) on the ten-point scale. A substitute part here carries consequences a trim piece does not: it needs engineering review, not a like-for-like appearance match.

Published physical properties
Weight, dimensions and material are still being researched. No packaging or shipping measurement is substituted for a part specification.
The Hamburg-Technic page sells the complete C4 bracket with bearing and specifies G64.20/G64.21. Confirm transmission code and mount revision before ordering. The aftermarket listing is not evidence that Hamburg-Technic supplied Porsche original production.
Enhanced alternatives
None catalogued. No aftermarket replacement for this reference has been found and verified. That is a finding rather than a gap in research: for structural 993 carriers and brackets, the aftermarket largely does not exist, which is precisely what makes them reproduction candidates. Any reproduction here is a safety-level 7 part and needs a qualification programme, not a copied outline.
