Porsche 981 S/GTS Tuning Guide

Porsche Cayman 981 S & GTS Modification Guide (2012-2016)

The Porsche Cayman 981 S and GTS (2012-2016) are already remarkable cars right off the factory floor, offering a finely balanced driving experience, excellent handling, and impressive performance. However, many owners choose to modify their vehicles to further enhance their driving pleasure, either by improving the car's sound, performance, or aesthetics. While the naturally aspirated flat-six engines in these models aren't typically modified for substantial power gains, there are still plenty of options to personalise your Cayman for both track enthusiasts and those who enjoy spirited driving on the road.

This guide covers some of the most common and popular modifications for the 981 Cayman S and GTS, giving you a better understanding of how owners enhance their cars.

Exhaust System Upgrades

One of the most popular modifications for the 981 Cayman S and GTS is upgrading the exhaust system. The standard exhaust note on these cars is already pleasing, but many owners opt for aftermarket systems to enhance the sound further and improve the car’s overall presence.

• Sports Exhaust Systems: These exhausts typically feature larger pipes and sportier tuning, which help amplify the engine’s natural tone. Brands like Akrapovič and PSE (Porsche Sports Exhaust) are popular choices. These systems can offer a more aggressive growl under acceleration and a more satisfying sound at higher revs.
• Downpipes: Replacing the stock downpipes with high-flow versions can help the engine breathe better, improving throttle response and sound, though the power gains may be minimal.

Although power increases are generally modest, the sound and driving experience are often the primary reasons for choosing an exhaust upgrade.

Suspension and Handling Enhancements

Porsches are known for their handling, and the 981 Cayman S and GTS are no exception. However, owners who want a more aggressive stance or improved performance, especially for track use, often turn to suspension modifications.

• Coilovers: Upgrading to coilovers is a popular choice for those seeking better handling and the ability to adjust ride height. Brands like Bilstein, KW, and Ohlins offer high-quality options that improve both comfort and performance. Coilovers allow owners to dial in the suspension to suit their driving style, whether that’s a firmer setup for track days or a more compliant setup for daily driving.
• Lowering Springs: For those who want a more aggressive stance without fully adjustable coilovers, lowering springs are a simple and effective modification. They reduce the car's ride height, giving it a sportier look and often improving handling by lowering the centre of gravity. Popular brands include Eibach and H&R.
• Anti-Roll Bars: Upgrading the anti-roll bars or sway bars helps to improve the car's cornering ability, reducing body roll and increasing stability. This is a common modification for track-focused drivers or those looking for a more planted feel on twisty roads.

Wheel Spacers and Tyres

Another common modification to enhance the Cayman’s stance and handling is the use of wheel spacers. These small components push the wheels outward, improving the car’s appearance and increasing track width for better stability in corners.

• Wheel Spacers: Spacers are a simple way to widen the car’s stance, improving its look and performance. A wider track can provide more grip, especially in tight corners, by improving the alignment of the wheels. Typically, spacers between 5mm and 15mm are popular, but it’s essential to ensure they’re properly installed to avoid any issues with wheel rubbing or alignment.
• Tyres: Upgrading to high-performance tyres can be a simple way to further enhance the car’s driving dynamics. Brands like Michelin, Pirelli, and Continental offer tyres that provide better grip, handling, and braking performance, which is especially important for those who take their Caymans on track days.

Exterior Aesthetic Modifications

While the Cayman 981’s design is already sleek and stylish, many owners like to personalise the car further with exterior enhancements that accentuate its sporty appeal.

• Carbon Fibre Components: Upgrading to carbon fibre parts such as mirrors, rear spoilers, side skirts, or diffusers can give the car a more aggressive look while also reducing weight. Many owners prefer these lightweight modifications, especially for those who regularly track their cars.
• LED Tail Lights: Changing out the standard tail lights for modern LED options can refresh the car's appearance. These can improve the visual appeal, adding a more contemporary feel to the rear end.
• Aftermarket Front Splitters and Diffusers: For a more track-inspired look, adding a front splitter or rear diffuser can increase downforce and enhance the car's aerodynamics. While these modifications are often cosmetic, they can improve stability at higher speeds.

Interior Upgrades

Although the 981 Cayman comes with a high-quality interior, owners may want to personalise the cabin to suit their style or driving needs.

• Sports Seats: While the Cayman comes with excellent standard seats, some owners opt for racing-style bucket seats for a more aggressive driving experience. Recaro and Sparco offer popular options that save weight and provide additional support during spirited driving.
• Alcantara Upholstery: For a sportier feel, swapping some of the interior materials for Alcantara can enhance the aesthetic, particularly on the steering wheel, centre console, or door panels. It offers a more tactile feel while also helping to reduce weight compared to leather.
• Upgraded Infotainment: Many 981 owners choose to upgrade the car's infotainment system with an aftermarket unit that supports modern technologies such as Apple CarPlay or Android Auto. This provides a more up-to-date user experience for those who value connectivity.

Brake System Upgrades

For owners who frequently track their 981 Cayman S or GTS, upgrading the braking system can provide improved performance under hard driving conditions.

• Performance Brake Pads: Upgrading to higher-performance brake pads, such as those from Pagid, Brembo or EBC, can help improve stopping power, reduce brake fade, and improve pedal feel during track days.
• Carbon Ceramic Brakes: While these are an expensive upgrade, PCCB (Porsche Carbon Ceramic Brakes) provide superior performance, especially for track use. They offer reduced weight and better heat resistance compared to traditional steel rotors.

Conclusion

The Porsche Cayman 981 S and GTS are already exceptional cars, but the ability to modify them allows owners to fine-tune their driving experience. Whether it's enhancing the exhaust sound, improving handling with coilovers, or adding aesthetic touches to the exterior, modifications can bring a more personalised and exciting experience to ownership. However, it’s essential to ensure any modifications are done carefully and with quality components to maintain the car's performance, reliability, and resale value. If you’re considering modifications, take the time to research what will best suit your needs and driving style, and consult experts or experienced Porsche technicians for advice.
