Brake Cooling Kit BMW M135i M140i F20 F21

Whether in normal driving, spirited driving or on track, there's no need to dwell on the bicycle-like brakes fitted to stock BMWs. After a few hard stops the bite fades, or the pedal even goes to the floor.

Fitting big brakes will push the limits, but you soon start wondering " how do I get brakes that last?" When you watch pro drivers lapping for hours, it seems out of reach. But looking closely at how race brakes are designed, while discs, pads and calipers are now available to the public, the main difference lies in cooling and thermal management.

Once properly cooled, pads and discs operate at a lower temperature, greatly reducing wear and maintaining their performance lap after lap.

This complete kit is therefore the essential complement to original or aftermarket brakes. It uses the original air intakes to channel air from the bumper, through the original duct and via the wheel arches to the final backing plate.

The F2x already has intake ducts in the front bumper, but these end in the middle of the wheel arch. To avoid air swirling randomly in the wheel arch, an air duct extension has been designed

Advantages:

• Uses the original aerodynamics and ducts
• Installation with minimal effort and modification
• Air delivered to the centre of the disc
• Protects bearings and ball joints from heat
• Powder-coated aluminium hub plate
• Direct replacement for the original part

IMPORTANT: Given the different chassis geometries and wheel and tyre combinations, it is impossible to cover every variant. In the worst case, the wheel could rub at full steering lock (which should only happen when parking). If this does occur, we recommend not manoeuvring at full lock, or fitting steering lock limiters.

Kit contents:

• 1x front left air duct inlet
  
• 1x front right air duct inlet
• 1x left mounting plate
• 1x right mounting plate
• 1x 3m air hose (ducting)
  
• 4x hose clamps
• Cable ties
• Heat-shrink sleeve to protect the ducting hose
  

Mike's tip:

"After adding 60mm ducting hoses to the big Alcon brakes on my M3 E46, I could do 35min sessions at the Bugatti circuit or at Spa, and it wasn't the car that gave up but the driver! It's sometimes complicated, but it's worth it"
