Identifying Your Rear Side Glass Configuration
To replace a damaged rear side window correctly on this liftback, the first step is separating the standard fastback body from the extended Executive or the Sport Turismo shooting brake. The fixed side window tucked into the rear pillar differs completely in geometry across these three profiles. On the fastback body, the glass tapers sharply into the rear hatch line, whereas the Sport Turismo carries an elongated, squarer pane that extends over an estate-style cargo area.
Beyond the exterior silhouette, Porsche equipped these side panels with three distinct glass compositions. Standard builds carry a solar-control green tint, typically referenced under Porsche base codes 971-845-297-Q for the left side and 971-845-298-Q for the right. If your vehicle has the optional dark factory privacy glass from the B-pillar back, the matching units correspond to 971-845-297-S (left) and 971-845-298-S (right). An alternative left-side variant appears under 971-845-297-J, while certain door-frame quarter assemblies list references like 971-845-025-AS. A third factory option is thermally and acoustically insulated laminated glass, which you can identify by looking closely at the exposed edge of your drop glass or the bug stamp in the corner: laminated acoustic units show a distinct sandwich line between two thin sheets of glass rather than a single solid tempered pane.
| Glass Spec | Visual Identifier | Sedan Left Reference | Sedan Right Reference |
|---|---|---|---|
| Standard Solar Tint | Light green hue, single tempered edge | 971-845-297-Q | 971-845-298-Q |
| Privacy Tint | Deep dark tint behind B-pillar | 971-845-297-S | 971-845-298-S |
| Acoustic / Insulated | Dual-layer lamination visible at edge | 971-845-297-J | Variant specific |
Surrounding Trim Finishes and Retention Hardware
The exterior perimeter of the quarter glass is framed by an integrated window surround that must match the rest of your exterior package. Porsche offered these mouldings in high-gloss black (often part of the High-Gloss Black exterior package), a subtle matte black finish, or bright polished anodized aluminum. Because these exterior trim pieces bend and crease under minimal leverage, replacement requires matching both the exact finish and preserving the trim alignment relative to the rear door's frameless window seal. When someone books a replacement with me, I am generally at their location within about sixty minutes ready to assess the specific trim package on-site.
Unlike the frameless drop windows in the rear doors that move along window regulators, this quarter panel is a stationary structural unit. It is secured to the body structure through specific factory hardware, including upper mounting brackets (971-853-910), lower brackets (971-853-730), specialized blind rivets (N-906-531-01), and threaded retention fasteners. Accessing these mounting points requires carefully unclipping the interior C-pillar trim panels, easing back the rear parcel shelf edges, and clearing the rear seat belt guides inside the cabin before the glass can be unbolted and detached.
