Rear quarter lower moulding rubber strip installed on Targa-body 911 and 964 models. It sits under the rear quarter decorative trim and acts as both a finish piece and a sealing component. Manufactured to match the original Porsche profile, the seal restores the proper fit and weather protection around the lower rear quarter area - a crucial detail for both cosmetic quality and preventing moisture intrusion on older Targa bodies.
Fits:
Porsche 911 1974 - 1989 Targa
Porsche 964 1989 - 1994 Targa
Diagram ref no 10
With age, the original rubber becomes brittle, shrinks, or deforms, causing gaps around the rear quarter moulding. This can lead to:
• Water leakage behind trim
• Corrosion on rear quarter panels
• Trim misalignment or rattling
• A visibly worn or uneven exterior appearance.
Installing a fresh seal restores proper fitment, protects bodywork, and improves the overall look of the Targa’s iconic rear quarter design.
When to Replace. You should replace this seal if:
• The rubber is cracked, shrunken, or missing sections
• The rear quarter moulding no longer sits flush
• Water or dirt is collecting behind the trim
• A Targa exterior restoration or repaint is being performed
• You notice vibration or noise from the rear quarter moulding

OEMatch Rear ¼ Glass — Fit, Finish, Clarity
Rear quarter glass and the associated seals help keep the cabin dry, quiet and protected on Porsche models. Properly chosen panels and their seals preserve appearance, limit water ingress and reduce wind noise, supporting long-term body condition and occupant comfort.
Available Types- Fixed rear quarter glass panels for non-opening windows
- Opening rear quarter glass (vent or pop-out) with fitted seals where applicable
- Complete glass-and-seal replacement units for easier installation
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original rear quarter glass.
OE (Original Equipment) refers to parts matching original specifications for the rear quarter glass and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM rear quarter glass engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Rear quarter glass is the side window positioned behind the rear doors. Some are fixed while others open slightly for ventilation. Replacements are available as plain glass panels or as matched assemblies that include moulded seals or bonded edges to restore correct sealing, alignment and finish.
Benefits Include- Restores watertight and airtight sealing to protect the interior and trim
- Reduces wind noise and vibration for a quieter cabin
- Protects bodywork from moisture-related corrosion where water ingress can occur
- Maintains visual alignment and factory appearance around the window aperture
- Impact damage such as chips or cracks from road debris
- Seal degradation from sunlight, ozone and age leading to hardening or shrinkage
- Corrosion or distortion of surrounding frames affecting glass seating
- Poor prior repairs or incorrect installation that compromise sealing or alignment
Replacing a damaged or weathered rear quarter glass and its seals helps prevent water ingress, removes sources of wind noise and reduces the risk of corrosion around the window aperture. Choosing a panel or matched assembly specified for Porsche models supports correct fit, preserves finish and helps retain the vehicle’s condition over time.
Advantages- Parts selected for Porsche applications to match shape and mounting points
- Materials specified for UV resistance and long-term sealing performance
- Direct-fit alternatives made to original-spec dimensions and tolerances for consistent installation
Fitting can appear straightforward but may require specific procedures such as correct positioning, sealing detail and careful reassembly to avoid panel damage. If you lack the right tools or experience, or if the vehicle includes hidden fasteners or sensors, seek professional installation. Recheck fasteners and seal compression after initial use.
