Speed Engineering Front Rotor Air Guide Plates for BMW F20 F21 F22 F23 F30 F31 F34 F32 F33 F36

Serious driving demands serious cooling. These Speed Engineering front rotor air guide plates deliver cool airflow straight into the disc hub so the vanes pull air through the ventilated rotors. Expect stronger fade resistance, more consistent pedal bite and improved pad and disc longevity on fast road runs and during hard track sessions.

Why enthusiasts choose this upgrade

• Feeds air to the rotor centre for efficient inside-out cooling using the disc’s own turbine effect.
• Optimised outlet angle for effective airflow where it counts, not just into the wheel arch.
• Lightweight, tough, powder-coated aluminium designed to handle heat, debris and UK weather.
• Bolt-on install reusing factory fixing points and screws - no extra hardware required.
• Ideal for fast road, track day and time on circuit where brake temperatures skyrocket.

We run these on our own cars and the difference is clear. Customers report steadier pedal feel, reduced fade during longer stints and fewer heat-related issues, helping consumables last longer when driven hard.
