• Position on Vehicle: Upper centre junction of the front windshield moulding - the chrome bar that sits at the very top of the windscreen frame, connecting left and right side mouldings.
• Function: Maintains proper alignment and continuity of the windshield trim, seals and aesthetic presentation, ensuring the joints between the individual moulding pieces meet correctly and avoid mis-fit, gaps or misalignment.
• Applications: Ideal for restoration-projects or repair when the original centre connector is missing, bent, corroded or mis-fitting - restoring that final piece of authentic front-end trim.
The connecting piece at the top of the windshield moulding plays a seemingly small but visually critical role in the appearance and function of the trim system:
• A damaged or missing connector can lead to mis-alignment of the moulding, visible gaps, uneven chrome lines and compromised seals around the windshield.
• Corroded or bent pieces can cause rattles, water ingress or degradation of adjacent mouldings.
• During a full body-work or respray the trim may be removed and may need replacement to ensure proper finish.
Replacing this part ensures accurate fitment, restores the intended finish, keeps water and debris out of the trim channel and maintains the correct aesthetic of the vehicle.
When to replace:
• The centre connector is visibly bent, missing or has removal damage.
• The Chrome finish is pitted, corroded or flaking.
• The moulding alignment at the windshield is uneven or shows gaps.
• You’re restoring the exterior trim to mint specification and wish to retain original style.

Porsche Rear Windscreen Seals | Design911 Rubber Weatherstrips for Protection & Structural Integrity
Rear windscreen seals are essential for maintaining your Porsche’s body integrity, weatherproofing, and interior comfort. These precisely moulded rubber components secure the rear glass in position while preventing water, dust, and air leaks. A properly fitted rear windscreen seal protects against corrosion, reduces noise, and ensures the car’s structure remains strong and watertight — vital for both performance and longevity.
At Design911, we supply a premium range of rear windscreen seals and trim sets engineered for perfect fitment and long-term durability. Manufactured from high-quality EPDM and UV-resistant rubber, these seals maintain elasticity, compression, and sealing strength even under extreme weather conditions. Whether for classic Porsche restorations, rear glass replacement, or performance maintenance, our products guarantee lasting protection and precision alignment.
What Do Rear Windscreen Seals Do?
Rear windscreen seals form a watertight and airtight bond between the glass and vehicle body, keeping your Porsche’s interior dry and quiet while supporting structural rigidity.
Core Functions:
• Securely hold the rear glass in position.
• Prevent water, air, and debris from entering the cabin or boot.
• Reduce wind noise and vibration during driving.
• Protect paintwork and interior trim from moisture damage.
• Contribute to aerodynamic performance and body stiffness.
A high-quality rear windscreen seal is vital for maintaining both comfort and structural integrity — particularly on performance or vintage Porsche models.
Why Do Rear Windscreen Seals Fail or Degrade?
Rear glass seals are constantly exposed to sunlight, temperature extremes, and environmental contaminants. Over time, these conditions cause the rubber to deteriorate and lose its sealing effectiveness.
Common Causes of Failure Include:
• UV exposure leading to cracking, hardening, and shrinkage.
• Heat and cold cycles causing deformation and fatigue.
• Contamination from cleaning chemicals or pollutants.
• Moisture ingress weakening the seal bond.
• Age-related wear or improper installation.
When seals degrade, water leaks, wind noise, and corrosion can develop — affecting both cabin comfort and long-term body condition.
Why Replace or Upgrade Your Porsche Rear Windscreen Seal?
Replacing worn or cracked rear windscreen seals restores complete weather protection and prevents costly interior or structural damage. Upgraded materials offer improved flexibility, UV resistance, and compression recovery.
Key Benefits:
• Restores watertight and airtight sealing performance.
• Eliminates leaks, wind noise, and rattling.
• Protects upholstery, wiring, and interior trim from water damage.
• Precision-engineered for Porsche 911, 944, 968 and other classic models.
