Are you regularly on the track and pushing your F8X M3/M4 to the limit? Then Speed Engineering have designed the right thing for you to cool your brake system!

This track kit is designed for the F80 M3 and F82 M4. In order to transport the air to the outlet of the brake ventilation, a suitable inlet is essential. The M3/M4 does not have factory inlet ducts in the front bumper like the M2 Competition. What your car has, however, are 2 coolers on the side behind the bumper! So why not use the existing airflow?

In order not to let the air swirl around randomly in the wheel arch after the cooler, we have developed a duct that can be installed with minimal effort and leads the air around the wheel and a connection via a 40 cm long hose (per side) to the outlet connects. Speed Engineering’s tests have shown that this does not create any significant back pressure behind the radiator and in the event of extreme speeds and increasing pressure, the ducts do not present any obstacles to the escaping air behind the radiator.

Kit includes:

• 1x air duct inlet left
• 1x air duct inlet right
• 1x air duct outlet left
• 1x air duct outlet on the right
• 1x air hose 1 meter
• 6x mounting screw
• 6x washer
• 4x hose clamp

IMPORTANT: The different models vary slightly in the wheel position. Coupled with different chassis geometries, as well as wheel and tire combinations, it is impossible for Speed Engineering to cover all vehicles. In the worst case, the wheel could touch slightly when the steering wheel is fully turned (which should only be the case when parking). This will not damage the tire.
