911 RSR 3.8 Tail Base, "Narrow Body" is a GT Racing-sourced tail base for 911R-style early 911 / RSR-style 911 builds. Use it when the part choice needs to support a RSR/IROC-inspired plan, not just fill a blank spot on the car.

Tail, deck-lid, grille, wing, and wickerbill choices change the rear profile more than almost anything else.
