HARD Motorsport Complete Brake Cooling Duct RACE Kit - BMW E46 M3


Product Description


  • Left and right Molded Inlets for the E46 M3 style bumper - 3" single outlet 
  • 2 - silicone 3" couplers
  • 2 - aluminum cooling tubes and mounting brackets
  • High temp 3" flex hose
  • (Option) left and right Brake Cooling Backing Plates
  • Mounting hardware and clamps included

The HARD Motorsport Brake Cooling Duct RACE kit is the only complete package that you need for mounting the plumbing for brake ducts to your E46 race car. Our kit incorporates a powder coated aluminum tube between the inlet and the flex tube, where the contact point can be the tire. This prevents you from instantly wearing a hole in your very expensive to replace flex tube.

Our kit uses a powder coated metal bracket that mounts to the frame of your BMW E46 M3, which allows removal of your front bumper while leaving the entire kit in place, for fast track repairs. No need to fumble with bolts, screws, and duct clamps, or unintentionally ripping your flex tubing in the process. 

Our quality ABS molded Duct Inlets are designed to endure the rigors of racing while saving you hundreds of dollars on your build budget! They're even lighter than expensive carbon fiber or resin alternatives.

Note: This kit requires that you run an E46 M3 style bumper for fitment of the Inlets. Removal of your washer fluid tank and AC plumbing is required.




Sold in pairs as a complete kit.

  1. Top Quality Kit! 5 Star Review

    Very well thought-out and made. Def beats Naca ducts and flex hose!! Alignment of the brackets wasn't perfect, but it's easy enough to get them to fit. Once everything is bolted down, it's a very solid setup!!
