Our Carbon Dive Planes for your E46 M3 replica 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 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! NASA GTS and BMW Prepared/Mod legal, as well as many other organizations. Check with your sanctioning body.

These race-quality carbon dive planes fit the non-M E46 using a M3 REPLICA front bumper only. We already offer dive planes for the factory M3 bumper but found the replica bumpers (commonly sourced from eBay and other Internet retailers) do not have the same contours and curves, leaving gaps along the inner edge when using our original design. There was a need for a different set of dive planes for the replica bumpers on the market. Note: due to variances in source and manufacturer, fitment may still vary from the flexibility of the urethane but should still fall within reasonable expectations for a racing part.

Kit includes one pair of dive planes and nut-plate hardware with bolts to make dive planes easily removable (requires permanent holes for the bumper cover).

Fitment Note 1: not for use with Genuine BMW, CSL, or CSL-replica bumper.

Fitment Note 2: Dive planes may not work with some aftermarket splitters due to how low they mount.
