When you want maximum support, minimum compromise, the Corbeau DFX delivers. This is a true fixed-back competition seat designed for drivers who actually push their cars—track days, time attack, autocross, or aggressive street builds where driver stability matters just as much as horsepower.

At Fab9 Tuning, we’ve installed and driven with the DFX in everything from dedicated track Miatas to high-power street builds. It’s one of our go-to seats when customers want serious lateral support, proper harness routing, and a fit that works well in compact chassis like the Mazda Miata.

Why We Like the Corbeau DFX

Fixed-Back Composite Shell
The DFX uses a lightweight composite shell that doesn’t flex under load. That means consistent driver positioning, better feedback, and no “twist” when you’re loading the chassis hard through corners.

Aggressive Bolstering (That Actually Works)
Deep shoulder and thigh bolsters keep you planted so you’re not bracing yourself with the steering wheel. Less fatigue, more control, better lap consistency.

Harness-Ready Design
Built-in harness slots support 4-, 5-, and 6-point harnesses, making it a proper solution for track and race applications when paired with the correct safety equipment.

Comfortable Enough to Drive To the Track
Unlike some ultra-narrow race shells, the DFX strikes a solid balance—supportive without being punishing. The breathable cloth material helps manage heat during longer sessions.

Fitment Notes (Especially for Miata Owners)

• Works well in NA / NB / NC / ND Mazda Miata chassis with the correct seat brackets

• Lower seating position possible compared to OEM seats (helmet clearance win)

• Best suited for drivers who want a snug, performance-oriented fit

• Side-mount required (sold separately)

If you’re unsure about fitment for your height, weight, or specific chassis, reach out—we’re happy to sanity-check your setup before you order.
