The Chevrolet Corvette Z06 GT3.R is one of the most advanced GT3 machines in iRacing, designed to bring the excitement of modern endurance racing to the sim. Developed alongside the production Corvette Z06 and factory endurance racing programs, it combines American muscle with sophisticated aerodynamics and race-bred engineering.
Powered by a 5.5L naturally aspirated V8 producing around 600 horsepower, the Z06 GT3.R is built to compete at the highest levels of GT3 racing worldwide. Its wide chassis, aerodynamic balance, and electronic driver aids make it one of the most competitive and accessible cars in the class.
Performance & Specs
- Engine: 5.5L V8, naturally aspirated
- Horsepower: ~600 hp (subject to Balance of Performance)
- Transmission: 6-speed sequential paddle-shift
- Weight: ~1,250 kg (BoP dependent)
- Top Speed: ~175–180 mph (track and setup dependent)
- Electronics: GT3-spec ABS and traction control
The Z06 GT3.R strikes a balance between raw V8 power and precise aero grip, making it a versatile option across a variety of circuits.
Handling Characteristics
The Corvette feels stable and confidence-inspiring at high speeds. Its wide chassis and downforce package provide excellent balance in medium- and fast-flowing corners.
- Stability: The car feels planted on high-speed straights and during heavy braking.
- Cornering: Strong mid-corner grip rewards smooth steering.
- Throttle: While stable, the rear can still snap loose under aggressive throttle application.
- Braking: ABS makes threshold braking more forgiving, but proper brake bias setup is crucial.
The Z06 GT3.R encourages precision — it rewards drivers who manage weight transfer and aero balance carefully.
Difficulty Level
The Corvette sits in the intermediate GT3 category. It is more approachable than twitchier GT3 cars like the Lamborghini Huracán GT3 EVO, but less forgiving than the Audi R8 LMS GT3. Drivers with a solid foundation in GT racing will find it a natural progression, while newer GT3 drivers benefit from its predictable handling and strong grip.
Real-World Tie-In
The Z06 GT3.R is Chevrolet’s first customer-available GT3 car, designed for both professional and privateer teams. It races in major series such as:
- IMSA WeatherTech SportsCar Championship
- FIA World Endurance Championship (WEC)
- GT World Challenge
- Endurance classics like the 24 Hours of Daytona, 24 Hours of Spa, and 24 Hours of Le Mans
In iRacing, the car mirrors this versatility, competing in IMSA, VRS GT Endurance, and major special events.
Why Drive the Corvette Z06 GT3.R in iRacing?
- Balance: A mix of stability, power, and downforce that makes it competitive across all circuits.
- Endurance Ready: Handles long stints well with predictable tire wear.
- Accessible Power: Naturally aspirated delivery feels smooth and linear compared to turbocharged GT3s.
- Versatility: Excels on technical tracks, fast circuits, and everything in between.
Whether you’re a casual racer looking for consistency or a competitive driver preparing for 24-hour events, the Corvette is a strong choice.
Tips for Success
- Smooth Driving: The car thrives on precision. Avoid jerky inputs.
- Use Downforce: Trust the aero grip in fast corners, but remember to adjust setups for track type.
- Tire Management: Sliding overheats the rear tires quickly. Focus on balance to maintain pace.
- ABS & TC: Use these tools to stay consistent, but avoid leaning on them too heavily.
The Chevrolet Corvette Z06 GT3.R represents a new era for Corvette Racing, bringing their endurance expertise to a global audience through the GT3 platform. In iRacing, it stands out as a car that blends raw American V8 power with cutting-edge GT3 technology.
It is stable, versatile, and fast — a car that can be enjoyed by both seasoned endurance racers and newcomers eager to step into top-level GT3 competition.
