Schropp SF4 GT4-Inspired Rear Wing for Mustang 6 Coupe – with TÜV Approval

The Schropp SF4 Rear Wing is our more subtle alternative to the large SF3 for the Mustang 6 Coupe. Our original Schropp design combines motorsport-inspired styling with GT4 influences and aerodynamic function, without sitting as high or appearing as aggressive as our SF3.

We developed the SF4 particularly for Mustang owners who found the height and aggressive appearance of the SF3 too extreme but still wanted a functional rear wing.

The more subtle alternative to the SF3

With its lower profile, the SF4 integrates more discreetly into the lines of the Mustang 6. It clearly changes the rear appearance of the car while remaining less visually dominant than our large SF3.

This makes the SF4 particularly suitable for Mustangs that should retain a performance-oriented appearance without having the rear wing dominate the overall design of the car.

Schropp design – more than just appearance

As with the SF3, it was important to us that the SF4 should not simply be a styling component. Positioned in the vehicle's airflow, the wing generates additional downforce at the rear axle as speed increases.

The SF4 can therefore help the rear of the Mustang feel more settled and stable at higher speeds. Compared with the considerably larger SF3, the concept is deliberately less aggressive.

Proven on high-performance Mustangs

The SF4 has also been used by customers with our Schropp supercharger conversions. Particularly on cars capable of regularly reaching higher speeds due to their significantly increased engine output, our customers have described the rear wing as a useful addition for increased rear-end stability.

This makes the SF4 particularly interesting for high-performance road cars: an aerodynamic addition for higher-speed driving combined with a considerably more subtle appearance than our large SF3.

Supplied with German TÜV parts approval – approved up to 300 km/h

The Schropp SF4 is supplied with a German Teilegutachten (TÜV parts approval) and is approved under the terms of the documentation for a maximum vehicle speed of up to 300 km/h.

A modification inspection is required after installation on the basis of the supplied Teilegutachten.

Installation

The SF4 is securely bolted to the boot lid. Installation therefore requires mounting holes to be drilled into the boot lid.

The rear wing is supplied unpainted, allowing it to be finished to match the vehicle or the desired overall design.
