• Application: These seals fit at the rear quarter panel to bumper interface on left (90150509320) and right (90150509420) sides. Designed specifically for classic 911/912 models to match original Porsche OE part specifications.
•  Function: Seals rear quarter panel to bumper, prevents moisture & debris ingress
•  Benefits: Restores original sealing, reduces noise, protects body panels

These seals provide a tight interface between the rear quarter panel and the bumper, ensuring a smooth, uniform transition and helping to prevent water ingress, dust, debris, and vibration from affecting the bodywork. By maintaining correct sealing and trim alignment, they support the vehicle’s structural aesthetics and help protect adjacent body panels from deterioration.

With age, exposure to heat, UV light, and movement can cause the original seals to dry out, shrink, crack, or detach. When this happens:
• Gaps can form between body panels, allowing water and moisture to enter.
• Road dirt and debris can collect between panels, promoting corrosion.
• Increased wind noise and vibration may be noticeable while driving.

Replacing worn bumper-to-body seals with high-quality seal restores the correct seal integrity, prevents water damage, and keeps your classic Porsche looking and performing as it should.

Replace the rear bumper to body seal if you notice:
• Hardening, cracking, or splitting of the seal material
• Water ingress around the rear bumper area
• Loose or flattened seals that no longer provide secure contact
• Increased vibration or wind noise from the rear body panels
• During full restoration or refurbishment of quarter panels and rear bumper trim
