911R Closed Louvered Quarter Windows is a GT Racing-sourced quarter-window piece for 911R-style early 911 builds. Use it when the part choice needs to support a lightweight 911R-inspired plan, not just fill a blank spot on the car.

Roof, hood, window, windshield, and Targa pieces need careful planning around seals, trim, and body structure.
