The rear bumper seal creates a weatherproof barrier between the bumper and the body panel. It prevents water, road debris, dust, and contaminants from penetrating the space where the bumper meets the vehicle structure. In addition to protection, it helps maintain a tight, factory-correct joiner surface that reduces wind noise and vibration.

Over time, original bumper seals can harden, shrink, crack, or split from heat, aging, and exposure to road conditions. When worn, seals can allow:
• Moisture ingress leading to corrosion
• Wind and road noise
• Dirt intrusion under body panels
• Visible gaps or uneven bumper fitment
Replacing a worn/recovering seal restores the correct factory sealing and finish - maintaining the visual integrity and long-term protection of your classic Porsche.

Replace this rear bumper seal if you notice:
• Cracks, splits, or missing rubber
• Loose or uneven bumper alignment
• Water entry or dampness near the rear panel
• Excessive wind noise while driving
• During bumper removal or restoration work
