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
