Porsche 718 Cayman GT4 RS 982 – The Pinnacle of Cayman Engineering
The Porsche 718 Cayman GT4 RS (982) represents the most extreme and track-focused iteration of the Cayman family. Unlike the standard GT4, the RS version takes engineering to another level, borrowing the naturally aspirated 4.0-liter flat-six from the Porsche 911 GT3. With over 9,000 RPM of thrilling performance, lightweight construction, and motorsport DNA infused into every detail, the GT4 RS stands as a benchmark for precision and excitement. At ATOMIC-SHOP, we provide a comprehensive catalog of upgrades to help Cayman GT4 RS owners elevate their cars even further — whether for the racetrack or spirited road drives.
Air Intake & Exhaust Systems for Porsche 718 Cayman GT4 RS
The heart of the GT4 RS lies in its high-revving engine. Optimizing the way it breathes and expels gases is essential for both performance and driving pleasure. Our range of air intake systems ensures maximum airflow with reduced resistance, while cat-back exhausts, manifolds, and downpipes enhance both power delivery and sound character. Crafted from lightweight titanium or stainless steel, these upgrades reduce overall mass while amplifying the raw, motorsport-inspired soundtrack.
- Performance intake systems with improved airflow and induction noise
- Cat-back exhausts engineered for maximum power and reduced weight
- High-flow manifolds and catalysts for track-ready responsiveness
Brake Systems – Precision Stopping for Extreme Driving
With a car as fast and aggressive as the GT4 RS, brakes must inspire confidence under all conditions. Our collection of performance brake pads, rotors, and brake lines is engineered for the demands of high-G cornering and repeated track laps. Lightweight rotors reduce unsprung mass, while upgraded brake pads offer fade resistance under extreme heat. Stainless steel brake lines and racing brake fluids ensure a firm pedal and consistent braking feel.
- Heat-resistant pads designed for track-level braking loads
- Two-piece lightweight rotors for improved cooling and reduced weight
- Performance brake lines for sharper pedal response
Suspension Kits & Chassis Reinforcement
The GT4 RS is engineered for razor-sharp precision, but for those who push limits, suspension upgrades provide the ultimate edge. Adjustable coilovers, air spring kits, and control arms allow for fine-tuning of ride height, damping, and alignment. Paired with strut braces and chassis reinforcements, these upgrades maximize grip and stability at high speeds and through technical corners.
- Height- and damping-adjustable coilover systems for custom setups
- Air spring kits for adjustable comfort and stiffness
- Performance braces to increase torsional rigidity
Cooling Solutions for Track Durability
Sustaining high performance on track requires efficient heat management. Performance radiators, oil coolers, and accessories keep engine and transmission temperatures under control during intense sessions. With the GT4 RS’s flat-six often pushed to its limits, these upgrades ensure long-term durability without compromising power output.
- High-capacity radiators designed for extreme heat dissipation
- Oil coolers to maintain optimal lubrication under stress
- Durable fittings and hoses for leak-free operation
Seats, Harnesses & FIA Safety Gear
The GT4 RS is built for motorsport, and the right seating setup enhances both safety and control. Our range includes sport seats for aggressive daily driving as well as FIA-approved racing seats and 4- or 6-point harnesses for track compliance. Combined with precision seat brackets, these components provide the driver with secure positioning under lateral G-forces, reducing fatigue while boosting confidence.
- FIA-approved racing seats for full track readiness
- Lightweight brackets for precise seat positioning
- Harnesses designed for maximum safety and driver focus
Aero Enhancements – Downforce Meets Design
Even though the Cayman GT4 RS is already aerodynamically optimized from the factory, further refinements are available. Diffusers, wings, and spoilers not only enhance downforce but also bring a more aggressive visual identity. Many upgrades are available in lightweight carbon fiber, delivering strength and style while shaving unnecessary weight.
- Carbon diffusers to channel airflow and improve stability
- Rear wings designed to increase downforce at speed
- OEM-fit aerodynamic upgrades for seamless integration
Wheels & Lightweight Components
Every kilogram matters in a performance machine like the GT4 RS. Upgraded wheels reduce unsprung mass, improving acceleration, braking, and handling precision. Forged alloys provide exceptional strength-to-weight ratios, while offering bold motorsport styling. Combined with lightweight hardware, these upgrades enhance both aesthetics and performance.
- Forged wheels engineered for reduced rotational mass
- Track-oriented fitments for maximum grip
- Performance wheel hardware for reliable durability
