Manufacturing
| Manufacturer | Rennline |
|---|---|
| Origin | 🇺🇸 United States Manufactured here Rennline, Vermont. |
| Process | Fabricated / Welded |
| Additively manufactured | No |
| Material | Chromoly Steel |
| Notes | Tubular space-frame, CNC-cut and TIG welded, matte black powdercoat. Not billet — a tube frame gets its stiffness from geometry, which is why it beats a heavier machined block here. Tube material not published; recorded as chromoly by convention for TIG-welded motorsport structures and needs confirming. |

| Notes | 1.4 lb (0.64 kg) saved against a gusseted factory carrier — note the comparison is to a reinforced carrier, not a plain one. The reason to fit it is that the original bends, cracks or breaks away from an engine mount under track use; the weight saving is incidental. |
Fitment
| 993 | Carrera, Carrera 4, Carrera S, Carrera 4S Explicitly NOT for Turbo. Rennline names the product "964/993 non Turbo". |
