The DRS-1 rear spoiler features a more aggressive streamlined design with screw-less dry carbon fiber endplates, elevating its aesthetic appeal for the GT4 RS street car.
Flex-Carbon Structure: In traditional wings, aluminum inner structures are used at the mounting points, however, in the SR Flex-Carbon Wing, aluminum has been replaced with the SR Flex-Carbon structure, reducing the weight by another 1.5kg. Mostly importantly, the flex-carbon structure provides unparalleled flexibility, similar to that seen in the McLaren F1 Flex Wing.
Passive DRS Effect: Our tests on the Shanghai F1 track demonstrates that the DRS-1 wing can passively drop back by ~1.5 degree of AOA at speeds between 150 to 270 km/h, resulting in an 8km/h increase in top speed compared to traditional wings. For the GT4 RS, this improvements translates to a lap time reduction of 0.5 seconds.
The strongest and lightest rear wing for the GT4 RS
Made of 100% racing-grade dry carbon fiber, the SilverRocket DRS-1 Flex-Carbon Swan Neck Wing is the lightest rear wing for Porsche GT4 RS. It provides more compressive strength while weighs 2.85lbs lighter than the stock GT4 RS wing and 1.64lbs lighter than the stock Clubsport wing.
Full CFD analysis with real aero data
The SilverRocket DRS-1 Flex-Carbon Swan Neck Wing went through comprehensive CFD analysis with exceptional modeling conducted by expert engineer. Our real aero data shows that at 125mph and 15° AOA, the SilverRocket Clubsport rear wing provides a whooping 472 lbs of downforce, which is 170 lbs more than the stock GT4 RS rear wing.
Flex-Carbon Structure with Passive DRS (drag reduction system) effect
We use the SR Flex-Carbon Structure to replace the aluminum inner structure in traditional wings, resulting in a 1.5kg weight reduction. Most importantly, it provides unparalleled flexibility, similar to that seen in the McLaren F1 Flex Wing.
6 calculated AOA (angle of attack) settings with aero data
The SilverRocket DRS-1 Flex-Carbon Swan Neck Wing offers 6 different angle of attack settings from -2.5° up to 15° designed from our CFD analysis aero data to provide great maneuverability for various driving preferences and track condition. Additionally, we use the high end SUS304 1/2H stainless steel for the L-mount that significantly enhances the rigidity at the connection points.
100% racing-grade dry carbon fibre
No inferior wet carbon fiber, no cheap glass fiber, we use 100% racing-grade dry carbon fiber, both inside and out, in the making of this wing to ensure its superior structural strength and ultra lightweight for track performance.
Rigorously tested on and off the track for superior performance and reliability
The SilverRocket Dry Carbon Fiber Clubsport Wing has been pushed to its limit with aggressive strength testing and intensive track driving to ensure its superior reliability that’s essential for your track experience.
3" Dry Carbon Wing Risers
The SilverRocket GT4 RS Dry Carbon Fiber 3-inch Wing Riser is the only carbon fibre riser available on the market that is 100% customized for the Porsche 718 GT4 RS model. It is the upgraded version of our best-selling GT4 RS 3-inch wing riser (OEM AlSi7Mg Casting).
Lightest Wing Riser: Weigh at only 3.29lbs (1,493g), our carbon fiber wing riser is 2.4lbs (1,089g) lighter than the stock wing bracket, making it the lightest wing riser for the GT4 RS.
Track-tested Quality: We use 100% racing-grade dry carbon fiber in the making of this wing riser to ensure its superior quality. The riser has been rigorously tested both in the lab and on track, showcasing great strength and stability under extreme conditions during our lap time record test. It can withstand over 500lbs of downforce even with the Clubsport Rear Wing with extreme stability.
Improved Rear Visibility: Not only does our wing rise increase downforce, but it also provides added visual benefits. See clearly through the rear mirror, crucial for high-speed racing maneuvers.
Enhanced Downforce: By extending the factory wing 3 inches higher, our wing risers enhances rear downforce, delivering exceptional performance on both the track and street.
Sleek Full Carbon Aesthetics: With its 100% dry carbon fiber material, sleek design, and attention to detail, this wing riser elevates the overall appearance of your GT4 RS to a whole new level.
Hassle-Free Installation: It is designed to be 100% OEM compatible and seamlessly integrates with your Porsche 718 GT4 RS. No need for drilling additional holes or complex modifications. Install with ease and get ready to experience the difference.
Function:
The SR GT4 RS Dry Carbon Fiber 3-inch Wing Riser aims to optimize the rear wing downforce by raising the factory wing by 3 inches, further improving the car's racing performance. Additionally, it improves rear-view visibility to ensure that the driver's overall rear-view vision, particularly in high-pressure track environments, is not obstructed by the wing, significantly enhancing driving safety.

Rear diffusers are extremely efficient downforce producing devices when designed properly. We set out to produce a functional rear diffuser for the Porsche 981 GT4 using state of the art R&D processes. The assembly blends function and form utilizing carbon fiber, sheet metal, and hard rubber.
Utilizing scan data, CAD, and ANSYS Fluent analysis software; we were able to design and produce a functional and aesthetically pleasing rear diffuser for this Porsche chassis.
The three main diffuser planes are produced from 2x2 twill, autoclave cured, carbon fiber; while the strakes are manufactured from durable polyurethane for longevity.
The entire unit bolts to chassis locations through multiple sheet metal brackets. There is absolutely no drilling or fabrication required for installing this rear diffuser.
*Outside stakes require slight trimming if installing with OEM GT4 muffler*
Kit Includes
• Diffuser Main Plane x 3 (Left, Right and Centre)
• Bracket (4)
• Strake, Hard Rubber (4)

Dramatically improve rear-end grip at speed with our 300mm chord, swan neck wing. The wing and full aero kit were designed in CFD to greatly improve the vehicle's performance around the track.
The wing alone has the ability to dramatically reduce lap times. Through back-to-back testing, we saw a reduction of 2.5 seconds at Thunderhill and 3.3 seconds at Laguna Seca on a relatively stock GT4 at only 4 degrees angle of attack with one of our customers. The Verus GT4 swan neck wing installs like the OEM wing; with no permanent modifications to the car necessary.
Construction on the rear wing is the same as seen in high-end Motorsports; which is how the wing only weighs a mere 8 lbs.
The uprights are CNC machined from 6061-T6 aluminum and were FEA analyzed to ensure strength was kept high while weight was minimized.

Make your Cayman GT4 look and perform like a proper Porsche GT car. Salter Aero Rear Wing Supports raises the OEM spoiler an additional 4", dramatically improving the overall look of the GT4. Track tested by professional drivers, these supports provide just enough added downforce in the rear to aid cornering without upsetting stock aerodynamics intended by Porsche. The OEM wing angle and its adjustability is maintained.
Designed using the latest rapid prototyping and 3D CAD techniques and software, the Salter Aero Rear Wing support for the GT4 is a step above all other "extension" type solutions. Inspired by the styling of the Porsche GT3 RS rear wing, we have designed a version that matches the GT4's sleeker, leaner proportions, providing an elegant and functional design that the GT4 should have had from factory.
Both the wing support and lower support covers are made using aircraft quality 6061-T6 billet aluminium and CNC machined using advanced milling machines. They are then bead blasted to a fine, smooth finish, eliminating any milling marks and then finally hard anodized to give a durable scratch resistant matte black finish.
Features:
• Increase of 4" over the OEM wing height.
• Unobstructed view from rear view mirror.
• All components are CNC machined out of 6061-T6 billet aluminium.
• Durable hard anodized flat black finish.
• Easy to install. No drilling, no cutting.
• Designed to fit internal OEM weather seal as per OEM, unlike other brands.
• Completely reversible back to stock.
