Rear Duct
*Now made of high-quality Kevlar Carbon!*
The brakes on the rear axle are subject to enormous heat on BMW models!
On racing vehicles, Speed Engineering were able to determine that the inside of the brake disc (despite the brake upgrade) on the rear axle builds up extreme temperatures. Apart from the high temperature development, an extreme difference between the inner and outer side leads to an uneven wear pattern on the brake pads.
The Speed Engineering solution is a plug & play upgrade and does not require any adjustments to the vehicle, no installation of a hose, clamps or other accessories making a wear-free system. The original screw points/forms on the wishbone are used for attachment.
The air is fed directly into the inside of the rim via a flow channel.
Important Information
Disassembly of the anchor plate is strongly recommended.
