Product Description

The Fabspeed Monoblock Wing Risers elevate and reposition your GT4’s rear wing to unlock improved aerodynamics, enhanced rear-visibility, and a more aggressive stance. CNC-machined from billet 6061-T6 aluminum, they lift the wing nearly 5.75" and shift it 1" rearwards — putting it into cleaner, higher-velocity airflow like a track-spec CUP-car wing. The result is greater rear downforce, sharper high-speed stability, and the kind of purposeful track-ready aesthetic that completes a serious build.

Fitment Notes

  • Designed for Porsche 981 Cayman GT4 (2016) and 718 Cayman GT4 (2020+). 

  • Also compatible with Cayman/GT4-based race cars and Cayman RS race cars using the same mounting geometry. 

  • Direct bolt-on installation: uses original mounting points, no cutting or welding required.

  • Adds only 0.57 lbs (≈ 0.26 kg) — negligible weight penalty for a big aero gain.

Included

  • Two billet aluminum riser struts (left + right) machined from 6061-T6 alloy. 

  • Mounting hardware (bolts, spacers) for direct installation. 

  • Adjustable-angle mounting supports (allowing multiple wing angle settings). 

  • Installation instructions (DIY-friendly setup, no cutting required).

Product Specs

  • Material: 6061-T6 billet aluminum (CNC machined)

  • Wing elevation: +5.75 inches (≈ 146 mm) from stock mounting height

  • Wing rear offset: +1 inch (≈ 25 mm) rearwards compared to stock mounting

  • Wing angle/Angle-of-attack settings: Adjustable — from factory ~21° up to 27.4° for added downforce or more aggressive aero balance. 

  • Structural rating: CAD-designed and stress-tested to withstand over 3 G cornering loads and up to 1,200 lbs of downforce.

Product Features

  • Improved Rear Downforce & Stability — Elevating and rear-offsetting the wing places it in cleaner, higher-pressure airflow, increasing downforce at speed for better high-speed stability and cornering grip.

  • Track-Grade Construction — CNC-machined from billet aluminum with a one-piece monoblock design, ensuring superior strength, stiffness, and longevity compared to cast or cheap riser kits.

  • Adjustable Aero Tuning — Multiple angle-of-attack settings (from near-stock to aggressive track spec) let you tune the car’s balance for road, track, or mixed use.

  • Better Rear Visibility & Safety — By lifting the wing higher than stock, rear window sightlines improve compared to low-mounted wings, enhancing rear-view visibility from the driver’s seat.

  • Minimal Weight Penalty — Adds only a fraction of a pound — negligible impact on handling or weight balance, while delivering meaningful aero gains.

  • Easy Bolt-On Installation — Designed for DIY or shop install with simple hardware; no drilling, cutting, or fabrication required.
