Diagram Ref No 25
What This Product Does
The seal occupies the joint where the rear quarter panel meets the bumper and body. It helps finish this junction while limiting the collection of moisture and road dirt between adjoining surfaces.
Functions
- Forms a sealing interface at the rear body joint.
- Helps separate adjoining painted edges.
- Completes the visible transition between bumper and quarter panel.
Technical Details
- Position: rear quarter panel, bumper and body junction.
- Length: 38 inches.
- Intended configuration: RSR / ST wide-body conversion or backdate.
- 90150509320: left-hand reference; diagram items 36 and 26.
- 90150509420: right-hand reference; diagram items 38 and 28.
Symptoms of Fault
- Seal material that has split, hardened or pulled away.
- Flattened sections or missing lengths at the joint.
- Accumulated grit and dampness behind the bumper.
- Paint abrasion where adjoining edges touch.
- Rattling that warrants inspection of both the seal and bumper fixings.
Why Replacement Matters
Renewing a deteriorated seal helps restore the joint's finish and reduces places where dirt can collect. During restoration or bumper removal, inspect the adjoining surfaces for corrosion and check the mounting hardware before fitting the replacement.
FAQs
Will this fit an unchanged standard-body 911?
The stated application is a wide-body RSR / ST conversion or backdate; donor model details alone do not establish suitability.
Will replacing the seal eliminate every bumper rattle?
No. Loose fixings, worn mounts or contact elsewhere may also need attention.
What preparation is recommended?
Remove trapped dirt, inspect the joint for corrosion and compare the replacement profile with the existing installation before fitting.
