E30 Brake Backing Plates - one pair

These backing Plates are made from stainless steel, and welded for durability. They are designed to route air into the vortex created by the spinning rotor.  This aids in cooling the rotors and helps prevent the brake fluid from over heating, allowing you to stop effectively when needed.

These backing plates ship to you as a pair and include 2 hose clamps to attach 3" diameter brake ducting. Easy installation does not require the removal of the wheel hub. 


Aerospace Grade Brake Ducting - 11 Foot length

This silicone ducting serves to channel cool air from the brake ducts to the backing plates. Their versatile yet durable flexible form can tolerate temperatures ranging from -80 deg. F to 600 deg. F.

This ducting will flex while maintaining it's form to route around the under panels without kinking or crumpling, thus maintaining a smooth flow of air.

The ducting, in combination with the brackets, will keep your front brakes cool in competition conditions such as endurance races as well as track schools.  Ships in 11 ft. section lengths only.
