Fabspeed Monoblock Wing Risers for Porsche 981 and 718 GT4 (2016–Present)

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.
