Porsche 718 Cayman / S / T - 2017 to 2024
The OEM front lip spoiler solution for the Porsche 718 Boxster / Cayman with standard bumpers.
A properly integrated and quality solution for your Porsche using the newer generation 991.1 OEM Porsche sports spoiler and a purpose built adapter kit to achieve compatibility with 718 Porsche models (2017-24)
Benefits of the 991 OEM Spoiler?
It creates a front-end aerodynamic profile similar to newer models and provides more usability than wrap-around spoilers due to increased ground clearance at the corners. It’s an original Porsche part that looks great and provides a refreshing update to the 987 Boxster front end.
How our adapter kit works:
991 Spoiler mounting points are not compatible with the 718 Boxster / Cayman so the kit solves this problem with a unique set of adapters that:
- are strong, secure and will not damage your bumper in cases of spoiler scraping or impacts
- eliminate the risk of damaging components (such as headlight washer lines) inside the bumper
- are both re-usable and reversible
Installation:
Almost zero DIY skills are needed
Step by step instructions provided
30 - 60 minutes of quality time with your 911 depending on the kit
No need to remove the bumper
A jack or ramps to raise the front of the car makes installation very simple

Fits:
Porsche 718 Cayman GT4 RS - 2022 to 2024
Porsche 718 GT4 - 2019 to 2024 *
Porsche 981 GT4 - 2016 *

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.

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.

Porsche 991.1 Carrera 2 / Carrera 4 - 2012 to 2016
Porsche 991.1 S Carrera 2S / Carrera 4S - 2012 to 2016
Function:
The Oxygen Sensor (also known as Lambda Sensor) is located in the exhaust manifold and measures the amount of unburned oxygen in your engine's exhaust. Based on the amount of oxygen, it sends a signal to your engine computer which then adjusts the air/fuel mixture for optimum engine performance and emission control.
Failure Symptoms:
Excessive fuel consumption, a faulty oxygen sensor can waste 30% of your fuel.
Driveability problems, such as engine surging or hesitation.
High hydrocarbon emissions, failing an emissions inspection.
The engine warning light may be on or service flag displayed.
The ecu/computer stores a mixture-related fault code.
When the oxygen sensor has stopped functioning completely, the catalytic converter may overheat and fail
Maintenance/Service:
Test and/or replace every 30,000 miles.
Perform periodic emission checks.
Watch for service light.
Vehicle manufacturers recommend periodic inspection and replacement of oxygen sensor.
