The Mercedes-AMG GT4 is one of the most stable and forgiving cars in iRacing’s GT4 lineup, making it an excellent choice for both beginners and endurance-focused drivers. Released in the 2017 Season 4 build (December 2017), it is powered by a 4.0L twin-turbocharged V8 producing ~430 horsepower. With its front-engine layout and AMG’s renowned durability, the GT4 emphasizes consistency and stability over long runs, providing a confidence-inspiring platform for drivers at every skill level.
Braking
- Brake Bias: Beginners should keep the bias slightly forward for stability under heavy braking.
- Trail Braking: Can be used lightly to aid rotation, but overuse may induce understeer.
- ABS Support: Trustworthy, but smooth pedal inputs remain the fastest way through braking zones.
Throttle & Turbo Power
- Smooth Throttle: Turbocharged V8 requires progressive application to prevent rear instability.
- Traction Control (TC): Higher TC levels are useful for stability when learning, with adjustments downwards as confidence builds.
- Exit Discipline: Patience with throttle on corner exits prevents wheelspin and maintains long-run tire health.
Cornering
- Entry: Brake in a straight line for predictable stability.
- Mid-Corner: Slight understeer bias, but stable and easy to manage.
- Exit: Smooth throttle is rewarded with traction and consistency.
Setup Advice for Beginners
- Aerodynamics:
- Higher Downforce → Adds stability and confidence on technical circuits like Nürburgring GP or Zandvoort.
- Lower Drag → Works well on high-speed tracks such as Daytona or Monza but requires careful throttle management.
- Brake Bias: 51–52% forward for stability.
- Suspension: Softer setups improve comfort and consistency during long stints.
Track Strengths
The AMG GT4 excels on circuits that reward power and stability:
- Daytona Road Course – Strong on straights, predictable in the infield.
- Watkins Glen – High-speed stability is a major strength.
- Silverstone – Balanced handling fits flowing sections and endurance racing formats.
The Mercedes-AMG GT4 is stable, predictable, and endurance-ready. Its forgiving balance makes it a great entry point into GT4 racing, while its turbocharged V8 ensures competitiveness across all formats. Beginners should focus on smooth throttle application, careful brake bias tuning, and higher downforce on technical tracks to maximize stability and confidence. Once mastered, the AMG GT4 becomes a reliable and competitive GT4 option in iRacing.
