Developed on the basis of a request from a well-known rental vehicle company at the Nürburgring, Speed Engineering offer brake cooling for the rear axle of all BMW F models (except M models, also available!). When used on the track, the M-Sport and M-Performance brakes in particular have large temperature differences between the inner and outer side, which leads to uneven wear of the pads. Removing the anchor plate only helps to a limited extent. The air duct picks up the air under the camber handlebars with a funnel and guides it directly to the brake disc hub. Analogous to the front axle brake cooling, we use the turbine effect, which enormously increases the efficiency compared to solutions that only blow on the friction ring.

Therefore, this product is the ideal addition to one of our VA cooling systems, or an existing solution.

Important: The anchor plate must be dismantled!
