Our Carbon Dive Planes for your E46 M3 front bumper are the next step in adding frontal downforce after adding a proper splitter. The added aero will keep your car's front end planted so the it doesn't fade into understeer through the duration of a race*. Additional frontal downforce can also reduce excessive wear on front tires that would otherwise be struggling for grip. All for just a little more than the cost of one race tire!
These race-quality carbon dive planes fit the E46 M3 front bumper only. Includes one pair of dive planes and nut-plate hardware with bolts to make dive planes easily removable.

Fitment Note 1: not for use with CSL or CSL-style bumper.
Fitment Note 2: Dive planes may not work with some aftermarket splitters due to how low they mount.
