Check fitment for your specific vehicle (model, year, engine) before ordering. Confirm the headlamp assembly fitted to the car, particularly if it has been changed during an earlier restoration.

Required Quantity
Two rings are required for the complete classic 911 / 930 Turbo / 964 headlamp installation.

What Is This Part?
This ring-shaped outer surround sits around the headlamp, finishing the junction between the lamp installation and the surrounding bodywork. It forms part of an assembly that also uses separate seals and fixing hardware. Its seating and fastening points allow the surround to remain in position around the lamp. When dismantling a headlamp for refurbishment, assess the ring separately from the lens, seals and internal mounting parts so that serviceable components can be retained.

What Does This Part Do?

• Surrounds the headlamp: Forms the visible outer border around the lamp.
• Finishes the bodywork junction: Covers the perimeter where the headlamp installation meets the front wing.
• Works with the fixing hardware: Provides the shaped surround that the associated fastening arrangement holds in position.

Why Replace This Part?
Dents, distortion or corrosion can prevent the ring from sitting evenly around the headlamp. Damage at its fastening point may also stop it from being secured correctly. Replacement is appropriate when inspection shows that the ring cannot be satisfactorily refurbished or securely refitted.

During removal, inspect the adjacent seals, fixing screw and mounting surfaces. An uneven or loose surround can result from a problem elsewhere in the installation, so check these components before assuming that the ring alone needs replacing. Headlamp refurbishment does not automatically require a new ring if the existing one remains sound and fits correctly.

When to Replace This Part?

• Visible deterioration: Corrosion, cracks or damaged edges make the ring unsuitable for reuse.
• Distorted shape: Dents or bending prevent it from sitting evenly around the lamp.
• Damaged fastening area: The fixing point is split, worn or unable to retain the surround securely.
• Persistent poor seating: The ring remains loose or uneven after the fixing and adjacent mounting components have been checked.
• Damage found during refurbishment: Removal reveals deterioration that was hidden while the ring was fitted.

Where Is This Part Fitted?
Location: Around the outer perimeter of the headlamp at the front wing, at the visible junction between the headlamp installation and the surrounding bodywork.
