When it comes to GT racing in Assetto Corsa, few cars demand as much respect and precision as the Porsche 911 RSR 2020. As the successor to the 2017 model, this car represents the pinnacle of Porsche’s GTLM and GTE engineering, brought to life through the official Porsche DLC pack.
Whether you are diving into a league race or hot-lapping on Nürburgring, here is everything you need to know about mastering this German masterpiece.
The RSR lacks ABS in GTE spec (though some versions have it for amateur driving). Locking the front left at T1 Monza is a rite of passage.
Most default mod setups are understeery to protect beginners. If you want to set lap records, you need aggression.
1. Rear Wing Angle
2. ARB (Anti-Roll Bars)
3. Differential (Preload)
The engine is a masterpiece. It revs high and delivers power linearly. Unlike turbo-charged competitors (like the BMW M8 GTE), there is no sudden spike in torque. This allows you to get on the throttle earlier in corner exits without worrying about the rear stepping out unpredictably.
The default setup is safe, but to be competitive, you need to tweak the car. Here are the "golden rules" for setting up the RSR 2020:
The rain hit the virtual tarmac of Spa-Francorchamps like a million tiny hammers. In the dim glow of his racing rig, Alex tightened his grip on the wheel. On the screen in front of him, the clock read 23:47. Tomorrow was the qualifying for the “24 Hours of Spa Sim Championship,” and he was still three seconds off the alien pace.
His weapon of choice? The Porsche 911 RSR 2017. It was a beautiful, stubborn beast. But Alex knew a secret. Hidden in the encrypted folders of Assetto Corsa was a mod he’d been beta-testing for a friend: the Porsche 911 RSR-20, a fictional evolution based on the 2019 Le Mans winner.
He loaded the car on the default layout, no assists, no racing line. The flat-six engine crackled to life through his bass shakers—a guttural, angry howl that vibrated up his spine.
“Okay, old girl,” he whispered. “Show me what you’ve got.”
First Lesson: The Rear is a Pendulum, Not a Rudder.
Exiting La Source hairpin, Alex did what he always did: he stomped the throttle. In the 2017 RSR, the rear would squat and grip. In this new 2020 beast, the rear stepped out like a startled horse. He spun, facing the wrong way on the Kemmel Straight.
“Too much, too soon,” he muttered, resetting the car.
He tried again. This time, he treated the throttle like a volume knob, not a light switch. He rolled onto the power, feeling the rear tires squirm through the wheel’s force feedback. The car didn’t bite. It sang. He flew up the hill, braking later than he ever dared for Les Combes. The carbon brakes bit with surgical precision.
Second Lesson: Downforce is a Contract.
Through the high-speed sweepers of Pouhon, the 2020 RSR transformed. It wasn't driving on the track; it was suctioned to it. Alex felt his own stomach lurch as the virtual G-forces tricked his brain. He took Pouhon flat out—something he’d only seen pros do on YouTube.
But entering the Bus Stop chicane, he braked a meter too late. The aero grip vanished like a liar’s promise. He slammed the tire wall.
Reset.
“The downforce gives you wings,” he thought, “but only if you respect its limits.”
Third Lesson: Patience is the Shortest Path.
Lap after lap. The rain stopped, leaving a drying line. Alex started mixing his brake bias, adjusting the traction control on the fly using his rotary encoders. He learned to listen. The Porsche’s engine note changed pitch just before the rear would slide. The steering wheel’s vibration told him when the front tires were begging for mercy.
At 1:47 AM, he crossed the line. His hands were sweating inside his gloves. The split time appeared.
2:12.087
The lap record was 2:12.300.
He hadn’t just beaten it. He’d demolished it. But more importantly, he hadn’t spun. He hadn’t crashed. He had danced with the car.
The Real Story
The next morning, during official qualifying, Alex didn’t use the secret 2020 mod. He couldn't; the server ran the standard 2017 RSR. But something had changed. His hands moved differently. He braked earlier but carried more speed to the apex. He rolled onto the throttle with the patience of a surgeon. He treated the car’s rear end not as a danger, but as a partner.
He qualified 4th. His best ever.
After the race—a chaotic, rain-soaked 24-hour simulation where his team finished 3rd—his teammate messaged him: “Dude, your sector two times were insane. What was your secret?”
Alex smiled, glancing at the hidden mod folder on his desktop.
“The future,” he typed back. “I just borrowed a little from the future to learn how to respect the present.”
He never published the 2020 RSR mod. He didn’t need to. The car had served its purpose—not to win a race, but to teach a driver that true speed isn’t about the machine’s power. It’s about the human’s patience.
And sometimes, you need a virtual ghost from tomorrow to tame the beast of today.
Epilogue
Months later, Porsche announced the real 2020 RSR. Alex watched the reveal trailer, heart pounding. The rear wing. The side exhausts. The diffuser. It was identical to the mod he’d driven in the rain that night.
He never found out how his friend got the data. Some say it was a leak. Others say it was a coincidence.
Alex knew the truth. The car doesn’t choose the driver. The driver chooses to listen.
And in Assetto Corsa, even a ghost can leave rubber on the asphalt.
The Porsche 911 RSR-19 (often referred to as the 2020 model in sim racing circles) represents the pinnacle of naturally aspirated GT engineering. In Assetto Corsa, it remains one of the most popular choices for endurance racing enthusiasts due to its unique mid-engine layout and iconic flat-six scream. The Engineering Shift: Why It Matters
For decades, the 911 was defined by its rear-engine layout. However, for the 2017 RSR and its 2019/2020 evolution, Porsche moved the engine forward of the rear axle.
Weight Distribution: Moving the engine created a mid-engine balance.
Aerodynamics: The shift allowed for a massive rear diffuser.
Tire Life: Better balance reduces rear tire overheating during long stints. Performance Specs in Assetto Corsa
While specific BOP (Balance of Performance) can vary by server, the base stats are formidable: Engine: 4.2-liter naturally aspirated flat-six. Power: Approximately 515 hp (depending on restrictor). Transmission: 6-speed sequential gearbox. Weight: Roughly 1,245 kg. Sound: Widely considered the best engine note in the game. Driving Dynamics and Handling
The 2020 RSR is a surgical instrument. Unlike the older "widowmaker" Porsches, this car is remarkably stable, but it demands precision.
🚀 Acceleration and Top SpeedThe naturally aspirated engine lacks the instant torque of the Ferrari 488 or BMW M8 turbos. You must maintain high RPMs and carry momentum through corners to stay competitive.
🎡 CorneringThe mid-engine layout makes the car rotate beautifully. It resists understeer better than the GT3 R, but aggressive downshifting can unsettle the rear end.
🛑 BrakingThe car is exceptionally stable under heavy braking. You can trail-brake deep into the apex, using the car’s rotation to set up a straight exit. Setup Tips for Sim Racers
To get the most out of the RSR in Assetto Corsa, focus on these three areas:
Aero Balance: Because of the large rear diffuser, the car is sensitive to ride height. Keep the rear slightly higher (rake) to pinned the nose down, but don't go too far or you'll lose high-speed stability.
Differential: If you find the car "snapping" on exit, soften the differential preload. This smoothens the power delivery to the rear wheels.
Gearing: Since it lacks turbo torque, ensure your gear ratios are tight. You want to be at the top of the rev range at the end of the longest straight. How to Get the Car
The Porsche 911 RSR 2019/2020 is available through the Porsche Pack Vol. 3 DLC for Assetto Corsa. It is also a staple in community mods and specialized racing platforms like iRacing and Assetto Corsa Competizione, though the original AC version remains a fan favorite for its moddability and sound.

The Porsche 911 RSR (2020) is a premier GTE-class racing machine frequently utilized in Assetto Corsa
through high-fidelity community modifications. While the official game DLC features the 2017 RSR, the 2020 "RSR-19" version represents a significant evolution, featuring a larger mid-mounted engine and relocated exhaust systems to improve aerodynamic efficiency. Technical Specifications
The 2020 model is defined by its mid-engine layout, which shifts the classic 911 weight bias to provide better balance for endurance racing.
Engine: 4.2-liter naturally aspirated flat-6 (the largest boxer engine in a 911 racer).
Power Output: Approximately 510–515 hp, depending on the Balance of Performance (BoP). Torque: 450 Nm to 489 Nm.
Transmission: 6-speed sequential gearbox with paddle shifters. Weight: 1,245 kg (minimum weight per regulations).
Aerodynamics: Features a massive rear diffuser made possible by side-exiting exhausts. Performance in Assetto Corsa
In the simulation, the car is praised for its precision and visceral auditory experience. Detailed performance stats can be explored on the Real Racing 3 Wiki.
Handling: Characterized as highly balanced with sharp, precise steering. Unlike the rear-engine road cars, it lacks the extreme "pendulum" effect but still requires careful weight management during trail-braking.
Audio: Known for its "screaming" engine note at high RPMs, which community members on Reddit consider one of the best sound experiences in the game.
Braking: Extremely effective with ventilated steel discs; visual details in many mods include glowing brake discs under heavy load. Setup and Driving Tips
To master this car, sim racers often focus on managing its unique mid-engine dynamics. Experts on Facebook suggest that seat time is the most critical factor. Porsche 911 RSR - iRacing.com
Because the engine is mid-rear mounted, the car has a polar moment of inertia that makes it rotate very quickly.
