Cleib Original Carbon Fiber or Fibreglass Rear Diffuser – Toyota GR86/ Subaru BRZ (ZN8/ZD8)
Transform the rear of your GR86 or BRZ with the Cleib original carbon fiber or fibreglass rear diffuser. Designed to streamline airflow beneath the bumper, this diffuser not only enhances styling but also delivers true aerodynamic gains.
Compared to the previous model, this version comes standard with carbon fiber underfins, a one-off design featured on our BRZ demo car. (Underfins remain carbon fiber whether you choose a carbon or FRP diffuser.) The front section of the diffuser, hidden when installed, is made of FRP for weight balance and durability.
It can also be installed seamlessly with aftermarket rear side spoilers, making it a versatile upgrade for both street and track builds.
Performance Benefits:
- Aerodynamic design for reduced drag and improved stability
- Integrated carbon underfins for aggressive styling and function
- Works with GR86 (ZN8) and BRZ (ZD8)
- Compatible with most aftermarket rear bumper spoilers
Track-Proven Performance:
- Guaranteed to improve lap times
- Combine with Crave’s front diffuser and side steps for maximum downforce
- Flows perfectly with other manufacturers’ aero parts
What’s Included:
- Rear diffuser assembly (carbon fiber or FRP + carbon underfins)
- Installation instructions
- Mounting brackets, bolts, and nuts
