The SilverRocket Porsche 718 Cayman GT4 RS SR EVO3 broke the fastest lap record for a production car at the Shanghai International Circuit.

Introduction

At the Shanghai International Circuit (SIC), the SilverRocket team, driving a Porsche 718 Cayman GT4 RS SR EVO3, set a new record for the fastest lap time for a street-legal car—2 minutes 08.82 seconds.

This achievement fully demonstrates SilverRocket's engineering prowess in vehicle aerodynamics, lightweighting, and chassis tuning, bringing this GT4 RS-based model to near-professional race car performance levels.

Background of the Shanghai International Circuit

The Shanghai International Circuit is 5.451 kilometers long, featuring long straights and numerous complex corners, making it an international-class track capable of comprehensively testing a vehicle's acceleration, braking, and handling performance.

Comparison References:

• F1 Lap Record: 1:32.238 (Michael Schumacher / Ferrari F2004)
• GT4 Race Car Average Lap Time: Approx. 2:05–2:10
• SilverRocket GT4 RS EVO3 Lap Time: 2:08.82 (Fastest Street-Leader)

This makes the SilverRocket one of the fastest street-legal cars currently on the SIC.

Technical Highlights Analysis

1. Aerodynamics

The EVO3 kit's aerodynamic design includes a DRS-1 Flex-Carbon adjustable rear wing, a high downforce front underbody, and a HR AeroDisc carbon fiber fairing, providing exceptional downforce and optimizing drag in high-speed corners.

Combined with the CC-1 PRO rear wing mount and angle-of-attack adjustment system, it allows for rapid adjustments to the car's balance under different cornering demands.

2. Suspension and Body Rigidity

The KW V4 Racing shock absorbers are a SilverRocket-exclusive tuned version, with damping optimized for high-speed cornering and heavy braking on SIC tracks.

The carbon fiber roll cage is FIA certified, balancing safety and rigidity while significantly reducing overall vehicle weight.

3. Braking and Handling

The Porsche Motorsport Clubsport braking system provides enhanced power and resistance to heat fade.

Equipped with a 320mm racing steering wheel and paddle shifter system, it allows the driver to maintain precise control at high speeds.

4. Lightweighting and Heat Dissipation

Extensive use of dry carbon fiber components throughout the bodywork results in comprehensive weight reduction, from the front bumper corners to the air intakes.

Active Cooling Wheel Cover System improves front wheel temperature management, enhancing endurance lap performance.

5. Tires and Grip

Sailun PT01 semi-slick tires (front 245 / rear 305) are specifically tuned for the EVO3, combining high grip and thermal stability, a key factor in improving lap times.

2:08.82 Lap Performance and Significance

The time of 2:08.82 not only broke the fastest record for a street-legal car at the Shanghai International Circuit but also approached the lap time of a professional GT4 race car.

This achievement reflects SilverRocket's systematic development achievements in aerodynamics, chassis setup, and tire matching.

The average speed across the entire lap exceeded 154 km/h, maintaining extremely high stability and braking efficiency even at the crucial braking corner (Turn 14) at the end of the long straight at the Shanghai International Circuit.

Significance of the Record

• Engineering Validation: The aerodynamic and chassis performance of the EVO3 kit was validated on a real track.

• Performance Benchmark: Established a new standard for street-legal lap times at the Shanghai International Circuit.

• Market Impact: Provided a benchmark performance target for modified cars in the GT4/Clubsport class.

• Brand Milestone: Established SilverRocket's leading position in performance development on the Porsche platform.

Summary

The SilverRocket Porsche 718 Cayman GT4 RS SR EVO3 set a new street-legal lap record at the Shanghai International Circuit with a time of 2 minutes 08.82 seconds. Through comprehensive enhancements in aerodynamics, weight reduction, chassis tuning, and thermal management via the EVO3 kit, SilverRocket has successfully brought a GT4 RS to near-race car performance.

This is not merely an engineering success, but a redefinition of "street car performance limits." SilverRocket proves that precise design and tuning can enable street cars to conquer world-class racetracks.
