AERODYNAMICS for F82-M4, Vol. 3

The BMW F80/82 M3/M4 front spoiler, side panels, and underpanel are now complete.

Downforce
The front spoiler and underpanel increase the effective area for generating downforce on the underside of the body.
The underpanel is angled to maximize downforce, and its design—which generates a large number of vortices—is a stroke of genius.
Since BMW’s cornering force depends on the grip of the front tires, this is a must-have item for drivers.

Cooling
The front spoiler is designed to draw in a large volume of air for cooling.
The underpanel is shaped to efficiently expel cooling air.
The side panels generate vortices to draw hot air out of the wheel wells.

Drag Reduction
These side panels reduce drag caused by wide tires that extend beyond the bumper.
Ideal for high-speed cruising and reaching top speed.
