Features:
-
High-Quality Carbon Fiber Construction: The GT3RS Full Conversion Kit is made entirely of top-grade carbon fiber, known for its exceptional strength, rigidity, and lightweight properties. The use of carbon fiber reduces the overall weight of the vehicle, improving acceleration, handling, and braking performance.
-
Complete GT3RS-Inspired Aesthetic: This conversion kit includes all the key components to transform the appearance of your Porsche 991 into a GT3RS look-alike, including front and rear bumpers, side skirts, rear wing, front splitter, hood, and more. The sleek and aggressive lines of the GT3RS components elevate the visual appeal of your 911, making it look more dynamic and track-ready.
-
Aerodynamic Enhancements: The carbon fiber parts in this kit are not just for looks—they are designed to optimize airflow and improve aerodynamics. The front splitter, rear diffuser, and rear wing all contribute to increased downforce, which enhances stability and grip, especially at higher speeds. This improves cornering ability and high-speed handling, making your 991 more responsive and planted on the road or track.
-
Lightweight Performance Gains: Carbon fiber’s light weight significantly reduces the overall weight of your Porsche, contributing to better handling, quicker acceleration, and more responsive braking. The reduction in weight enhances your car’s agility and overall performance, whether on the street or at the track.
-
Track-Ready Look with Functional Design: The GT3RS Full Conversion Kit doesn’t just make your Porsche 991 look more aggressive—it also incorporates functional elements that improve vehicle dynamics. The larger rear wing increases downforce, while the redesigned front splitter and side skirts channel air more efficiently to reduce lift and enhance stability.
-
Perfect Fitment for Porsche 991 (991.1 & 991.2): Specifically designed for the Porsche 991 models (both 991.1 and 991.2), the GT3RS Carbon Fiber Full Conversion Kit offers seamless fitment with OEM-quality precision. The components integrate perfectly into the existing body lines, ensuring a clean, professional finish with no modifications required.
-
Durable and UV-Resistant Finish: The carbon fiber components are coated with a UV-resistant finish to prevent fading or yellowing over time. Additionally, the scratch-resistant surface ensures that your car's new body parts maintain their premium look, even with regular use.
-
Enhanced Handling and Stability: The aerodynamic improvements from the kit help reduce drag and increase downforce, improving your Porsche’s cornering stability, braking performance, and overall high-speed handling. The added downforce creates better tire grip and a more confident driving experience, especially during aggressive driving or track sessions.
-
Comprehensive Kit for a Complete Transformation: The GT3RS Carbon Fiber Full Conversion Kit is designed as a complete solution to fully transform your Porsche 991. The kit includes everything you need to give your vehicle the iconic GT3RS look, including front and rear bumpers, side skirts, rear wing, hood, front splitter, and more.
