The G82 M4 already looks aggressive from the factory. This Underground build takes it further with race parts that were never meant to see an inspection lane: a Flossmann GT Street hood and wing, full carbon aero and laser tail lights.

The build plan
The Flossmann GT Street kit brings the GT Street hood, vented front fenders and a GTR rear wing. It keeps the body of the car but completely changes its attitude, especially from behind.
SFXLA carbon completes the aero: a front lip that drops the nose, side skirt extensions that close the line between the arches and a full carbon rear diffuser under the wing.
CSL laser style tail lights finish the car. At night nothing else looks like it. This is a car for people who want their M4 to look like it escaped from a race paddock.
