1. Performance Exhaust Systems
Upgrading the exhaust system on your Porsche Cayman 987 or 981 offers one of the most noticeable improvements in both performance and character. By reducing back pressure and improving gas flow, a well-designed exhaust increases your horsepower and sharpens throttle response. The change in tone is equally rewarding, bringing out a more focused, motorsport-inspired note that complements your car’s dynamic nature.
Material choice plays a key role. Stainless steel systems are durable and corrosion-resistant, while titanium options offer impressive weight savings and a more distinctive sound profile. Whether you’re driving daily or aiming for weekend circuit use, selecting an exhaust with high-flow catalytic converters ensures your compliance and efficiency. If you’re considering a Stage 2 remap, pairing it with a sports cat or de-cat pipe helps maximise your gains and maintain safe exhaust temperatures.
Compatibility is crucial. Exhaust systems must be selected based on your engine type, gearbox configuration, and whether your car already has aftermarket parts fitted. Noise regulations and emissions should also be factored in, particularly for road-registered cars.
Regal Autosport curates our range of performance exhaust upgrades to meet your specific needs, be it weight reduction, tone enhancement, or increased flow. Our knowledgeable team can guide you in selecting and installing the ideal exhaust system for your Cayman. Get in touch with us today on 02380558636 for specialist advice.
2. ECU Remapping and Tuning
Remapping your engine control unit (ECU) transforms how your Porsche Cayman 987 or 981 delivers power. By adjusting the factory calibration, ECU tuning refines ignition timing, fuelling, and torque strategies to suit your performance driving. The result is sharper throttle response, stronger mid-range pull, and improved flexibility across your rev range.
For those looking to keep hardware changes minimal, a Stage 1 ECU tune is the most accessible option. It works seamlessly with your stock components to enhance performance without compromising reliability. If you’ve installed supporting hardware like a high-flow intake or upgraded exhaust system, a Stage 2 tune is ideal. It builds on your modifications and fine-tunes engine parameters to safely unlock further gains.
Custom mapping is available for more advanced builds. At Regal Autosport, our tuners can calibrate the ECU around your car’s unique characteristics, whether you’re preparing for competitive use or have specific fuelling needs. Fuel type, ambient conditions, and load expectations are all taken into account to ensure safe, repeatable performance.
Proper ECU calibration is not just about raw numbers. A refined map improves your car’s drivability, reduces unnecessary engine strain, and supports consistent delivery even during your spirited use. It also ensures all your systems work in harmony, including your traction control and gear shift logic.
At Regal Autosport, our ECU tuning services are delivered with data-backed precision and full compatibility with your vehicle’s existing control systems. Email us your enquiry, or visit our dedicated service page today to learn more about ECU tuning for your Porsche Cayman.
3. Suspension Upgrades
One of the most effective ways to sharpen the handling of your Porsche Cayman 987 or 981 is through a targeted suspension upgrade. From coilover systems to uprated anti-roll bars, investing in the right chassis components significantly improves your steering response, road feel, and cornering stability, especially if you’re building a track-heavy setup or simply looking to reduce body roll for fast road use.
Modern coilover systems give you precise control over ride height and spring rate adjustment, allowing you to tailor your car’s setup to your preferred driving conditions. Whether you’re focused on road comfort or dialled-in track performance, Regal Autosport’s expertise in fine-tuning damper settings makes a noticeable difference in how your Cayman responds through corners.
In addition, components like sway links, camber plates, and GT3 lower control arms offer improved geometry and wheel alignment flexibility. These upgrades work together to help you maintain tyre contact under load, boosting grip during hard cornering. When pushing limits, a well-optimised geometry setup ensures your car remains balanced and predictable.
Bump steer adjustment kits and reinforced tie rods further refine steering accuracy, especially under aggressive braking or mid-corner load changes. These parts are often overlooked but play a vital role in improving your driving confidence and chassis feedback. For serious performance builds, suspension modifications should always be matched with proper alignment.
At Regal Autosport, we use digital geometry tools to achieve repeatable results and offer full consultation to ensure your suspension upgrades suit your driving style and needs. Call us today on 02380558636 to explore your suspension options.
4. Brake System Enhancements
Reliable stopping power is essential when upgrading your sports car for performance driving. For Porsche Cayman 987 and 981 owners, improving your braking system can deliver substantial gains in your control, safety, and confidence, especially during spirited use or track sessions.
A complete brake kit typically includes larger brake disc rotors, uprated pads, braided brake lines, and performance fluid. These upgrades enhance bite, reduce brake fade under heat, and provide better pedal consistency. Unlike factory setups designed for road use, performance brake systems cope more effectively with repeated heavy braking and high-speed deceleration.
Heat management is equally important. Components like brake duct deflectors channel airflow directly to your braking surface, helping lower disc temperatures during aggressive runs. When combined with quality pads and fluid, your setup minimises wear and maintains responsiveness throughout your driving session.
Upgraded discs often feature slotted or drilled surfaces to evacuate gas and debris while improving wet-weather braking. Pairing with stainless steel braided lines delivers a firmer pedal feel and improved modulation under load. Together, your enhancements transform the braking characteristics of your Cayman, delivering reliable stopping performance whether you’re on the road or pushing harder on the track.
For high-performance builds, we also recommend pairing your brake upgrades with engine protection measures such as a deep sump or windage tray, which help maintain oil control under heavy deceleration and lateral forces. These additions protect your engine’s integrity while you focus on braking later and harder into corners.
At Regal Autosport, our brake specialists can upgrade your Cayman’s braking system for optimal performance. Contact us today on 02380558636 for an expert consultation.
5. Lightweight Wheels and Performance Tyres
Reducing unsprung weight and increasing grip are essential goals when refining the performance of your Porsche Cayman 987 or 981. Lightweight forged wheels offer strength and weight advantages over cast alternatives, improving your handling response and enhancing your suspension’s ability to track the road surface accurately.
By choosing lightweight alloys, you reduce rotational mass, leading to quicker acceleration, sharper braking, and more predictable cornering. The benefits are particularly noticeable in fast direction changes and uneven surfaces, where suspension components can respond more effectively with less weight to control. Your upgrade is especially effective when combined with other suspension tuning elements such as sway links, camber plates, and GT3 lower control arms.
The tyres you pair with your wheels are just as important. High-performance compounds offer better grip, reduced braking distances, and sharper steering input. From track-ready semi-slicks to road-biased ultra-high-performance options, selecting the right rubber for your track-heavy setup or fast-road use has a significant impact on your car’s overall behaviour.
Upgrading your wheel and tyre package also allows you to optimise your ride height and spring rate adjustment through better suspension calibration. Matching your wheel dimensions with coilover geometry or tie rod configuration helps you reduce tramlining and improve your stability at high speeds. Whether you’re tackling back roads or preparing for your next track day, your upgrades contribute to your more balanced, confident driving experience.
If your focus is both on aesthetics and performance, a bespoke set of wheels can also complement your vehicle’s look, especially when paired with finishing details such as tri-bar sequential indicators or painted brake callipers.
At Regal Autosport, we provide wheel and tyre packages tailored to your Cayman’s performance goals. Reach out to us today on 02380558636 to find your perfect setup.
