E46 Spare Tire Trunk Delete with Differential Cooler Mounting

Overview

Engineered for serious track and race applications, this E46 trunk panel replaces the factory steel spare tire well with a lightweight, high-strength aluminum solution developed on STROM B46 race cars. Constructed from precision laser-cut .080" 6061 aluminum, the panel is designed to streamline rear-mounted component integration while reducing weight and eliminating the need for custom fabrication. It features built-in mounting provisions for a Setrab fan pack, differential cooling pump, and air jack pass-through—making it an ideal foundation for a complete E46 differential cooling system with a clean, professional installation.
