Will this scrape on steep driveways or speed bumps?

The Taka design extends moderately below the bumper line. Before installation, measure ground clearance at your vehicle's lowest points under load and verify the diffuser mounting height against your driveway approach angles. Adjust installation angle if needed to match your typical driving terrain.

Is this diffuser purely cosmetic or does it provide real downforce?

The Taka profile is engineered to manage airflow separation at the rear bumper, creating functional downforce at highway speeds. It's not a race-spec unit, but the geometry delivers real aero benefit alongside visual styling.

What prep does the carbon fiber need before installation?

Sand the mounting surface on your rear bumper with appropriate grit and clean thoroughly before bonding or bolting. Once installed, the clear coat protects the exposed weave from UV damage — periodic washing and wax application will maintain the finish long-term.
