Porsche 982/718 GT4RS / Spyder RS

Tuning Porsche 718 GT4 RS / Spyder RS (982): Maximum Expression of Racing Technology

The Porsche 718 GT4 RS and Spyder RS are the apex of the 982 mid-engine platform. For the first time in the series' history, the Cayman received a full-fat 4.0L engine from the 911 GT3, capable of screaming up to 9000 RPM. In Ukraine, these cars have become a true challenge for drivers seeking to dominate the Chaika Autodrome. However, the extreme character of the RS requires a professional approach to chassis setup and thermal management. ATOMIC-SHOP offers ultimate solutions for GT4 RS and Spyder RS refinement, based on motorsport experience and premium brand integration.

Our approach focuses on unleashing the soundtrack via Akrapovič titanium systems, professional Manthey Racing chassis tuning, and ensuring braking stability under extreme loads using AI-100 fuel.

4.0L GT3 Engine: Breathing and Performance

The GT3 engine in the 718 chassis features a unique intake system that makes the cabin acoustics truly incredible. To maintain its efficiency, we recommend:

• BMC High-Flow Filters: BMC filters ensure a stable laminar airflow, critical for a naturally aspirated motor consuming a colossal volume of oxygen at high RPMs. This is a mandatory upgrade for consistent power.
• LiteBlox Lithium Battery: Every gram counts for the GT4 RS. Replacing the stock battery with a LiteBlox lithium unit saves up to 15 kg, significantly sharpening steering response and overall dynamics.
• AI-100 Fuel: High-octane fuel in Ukraine is vital to prevent detonation at high RPMs, especially during summer track sessions.

Exhaust System: Akrapovič Titanium Voice

The stock 718 GT4 RS exhaust is limited by strict environmental regulations and OPF filters. ATOMIC-SHOP offers game-changing solutions:

• Akrapovič Evolution Line (Titanium): This titanium system not only reduces vehicle weight but also provides a high-pitched, racing timbre. It allows the GT3 engine to breathe freely, adding power in the "combat" RPM range.
• Slip-On Race Line: For those seeking maximum weight reduction without modifying the headers, we offer the Slip-On solution, perfectly compatible with factory valves.

Chassis and Aerodynamics: Manthey Racing Magic

The 718 GT4 RS is already a phenomenal car, but the Manthey Racing (MR) package transforms it into a true track weapon:

• Manthey Racing Coilover Kit: Developed alongside KW, this suspension allows for perfect tuning of the car for the specific curbs of the Chaika Autodrome, ensuring maximum mechanical stability and control.
• Girodisc 2-Piece Rotors: We recommend replacing stock PCCB ceramics with Girodisc 2-piece steel rotors for intense track use. This provides better braking modulation and drastically reduces operating costs.
• Endless MX72 / ME20: Endless brake pads are the #1 choice for professional track use. They withstand extreme temperatures without losing friction coefficient.
• MR Aero Kit: Additional aero elements from Manthey Racing substantially increase downforce, making the car perfectly balanced at high speeds.

FAQ: ATOMIC-SHOP Technical Expertise

Why is the GT4 RS sound so loud inside the cabin?
This is due to the intake system, where the air intakes are located exactly where the rear quarter windows would be. This is a Porsche engineering solution for better airflow, which we optimize using BMC filters.

Is AI-100 fuel safe for RS versions?
Yes, it is the only way to ensure correct ignition timing at 9000 RPM. Lower octane ratings will result in power retards due to detonation.

What is the benefit of the Manthey Racing package for the Spyder RS?
While the Spyder RS is more street-oriented, the MR package adds composure and stability at high speeds, which is critical when driving with the top down.
