HARD Motorsport Low Profile Brake Cooling Chamber Style Duct - BMW E9X


Product Description

Overheating your brakes can end an entire weekend at the track and is the most common reason for premature brake failure and wear. 

Try fitting the standard 3" Flex Hose onto the E9X chassis and you'll quickly realize that you're going to be buying a lot of expensive Flex Hose.  There is really no way to use a full size hose without your tires chewing through it, even on a moderate turn, or crushing it in your suspension components.  Every available kit out there uses a smaller diameter hose and was a bit of a "choose your own adventure in brake cooling" that ends up costing you much more in replacement hose than we felt necessary.

Also, have you tried to find 2.5" hose in a pinch? Good luck!!!

HARD Motorsport now has the answer. Our Chamber Style Ducts mount flat against your frame rail to deliver that cool air straight to your brakes.
Our carefully CAD designed duct will allow much greater steering angle and should clear up to a 10" wide wheel without interfering. Manufactured with high-quality, lightweight plastics and quality hardware.


Note: Add this duct system to any intake or backing plate available that utilizes 3" hose connections, or take a look at some of our other full Brake Cooling kits for the E9X chassis...COMING SOON.
