Purpose and vehicle placement

The described window is intended for installation in the rear section of the body on the right side, in the area behind the passenger door. This placement is crucial for both the structural rigidity of the body and for visibility and interior cabin lighting.

The element was designed specifically for the first generation Audi R8 Type 42, ensuring it maintains the correct curvature, tilt angle, and contact line with the seals and body frame. Original glazing helps avoid issues with leaks, wind noise, or improper fitment, which often occur with aftermarket parts of imprecise dimensions.

Technical characteristics of the glazing

As an element from the Car Windows group, the Audi R8 42 Gen1 Rear Window Quarter Glass Glazing AS2 Right O/S is made of safety glass with the appropriate homologation class, adapted for installation in the rear zone. The window construction includes:

• appropriate glass thickness to maintain rigidity and resistance to body stress,
• a profile matched to the characteristic side line of the R8 model,
• edge geometry enabling proper cooperation with seals and mounting elements.

Glazing configured in this way supports the stability of the side structure while providing proper illumination of the space behind the seats, which is both functional and visually significant.

Benefits of using an original used window

Using an original rear right quarter window in an Audi R8 42 Gen1 allows you to maintain the stylistic and technical consistency of the entire body. A used OEM part is a sensible choice in situations where replacement is necessary due to mechanical damage or during accident repairs, and where factory fitment is the priority.

Key advantages of this solution include:

• preservation of the original body line – no optical distortions or incorrect gaps,
• compatibility with factory mounting and sealing points,
• the ability to restore the original rigidity of the side body structure,
• more predictable performance during operation compared to low-quality aftermarket replacements.

Use in Audi R8 repairs and restorations

The Audi R8 42 Gen1 Rear Window Quarter Glass Glazing AS2 Right O/S is suitable for both standard replacement of damaged glass and more extensive bodywork repairs in the rear section of the vehicle. Choosing an original part reduces the time required for fitting and adjustment, which is essential for precise repairs on sports cars.
