Challenge Engineering has developed one of the strongest, lightest trunk lids available for the E9x M3 with their full Carbon Kevlar trunk. The Challenge trunk correctly combines several types of carbon fiber weave, a strong core material, and carbon kevlar inner lining for a part that is optimized for minimum weight while also maximizing strength. The trunk is styled to integrate a smooth rear spoiler that follows the factory body lines without appearing excessive or attracting unnecessary attention.

Also look out for Challenge’s newest project- a full Carbon/Carbon Kevlar trunk with a complete factory-like appearance! The trunk looks exactly like the factory original trunk, but comes in at about 1/3 of the weight.
