Mugen Front Under Spoiler and Diffuser (GROUP B) – Honda Civic Type R FL5
The Mugen Front Under Spoiler and Diffuser (GROUP B) is a competition-grade dry-carbon lower spoiler designed for FL5 owners who want genuine aerodynamic gains without unnecessary weight. Replacing the factory lower bumper panel, the diffuser reshapes the airflow beneath the car to generate additional downforce and improve front-end stability at speed.
Integrated dry-carbon brake and radiator ducts help direct cool air exactly where it’s needed, supporting consistent brake performance and more efficient cooling under high load. The dry-carbon construction keeps weight to a minimum while maintaining excellent rigidity and durability.
Lowering the front bumper by approximately 42.5 mm, the GROUP B spoiler gives the FL5 a more purposeful stance with a sharper aerodynamic entry angle. Developed with motorsport input, it balances cooling performance, downforce, and strength for both fast road use and track applications.
Key Features:
- Dry carbon fibre construction for maximum strength with minimal weight
- Aero under-panel corrects airflow to increase downforce
- Integrated brake and radiator ducts improve cooling efficiency
- Lowers front bumper by roughly 42.5 mm for enhanced aero profile
- Motorsport-inspired design for stability at speed
- Direct replacement for OEM lower bumper panel
- Supplied unpainted with visible twill carbon finish
