Manufacturing
| Manufacturer | Porsche AG |
|---|---|
| Origin | 🇩🇪 Germany Vendor head office — place of manufacture not stated |
| Process | Prepreg / Autoclave Cure (dry carbon) |
| Additively manufactured | No |
| Material | Carbon Fibre (prepreg, autoclave cured) |
| Notes | An anti-roll bar works in torsion, which is an awkward load case for unidirectional fibre — this is genuine engineering rather than trim. It is also unsprung and rotating-adjacent mass, so the effect exceeds the figure. |
Published figures

|---|---|
| Notes | Front and rear bars plus rear coupling rods save 11.9 lb (5.4 kg) — more than the carbon roof, mirrors and wing combined. |
