BimmerWorld's Carbon Dive Planes for your E90 or E92 M3 front bumper provide additional 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 bumper profile of the E90 M3 sedan and E92 M3 coupe front bumper. They have more surface area (larger) than the factory GT4 dive planes. This kit includes one pair of dive planes and nut-plate hardware with bolts to make dive planes easily removable. Some trimming/cutting and modification may be necessary to install these dive planes, depending on the particular front splitter they are used with. To make this kit as flexible to your install as possible, the dive planes are not pre-drilled, allowing you to drill and place your fasteners as needed.

Note: Dive planes may not work with some aftermarket splitters due to how low they mount. Modifications such as notching, trimming or slits may be required on some splitters. Please refer to pictures for reference.
