Porsche 911 GT3 R (992) in iRacing
I bought the 992 GT3 R about two seasons ago and it’s become my main GT3 car. The 4.2-litre flat-six sounds brilliant through my headset, and I genuinely enjoy the rear-engine weirdness of it. Nothing else in GT3 drives like this thing. Cost me $11.95. I run it mostly in IMSA and GT Sprint. Tight, technical tracks are where it comes alive. The rear-engine traction out of slow corners is bonkers. Spa and Monza are harder work because the understeer bites you in the fast stuff. It’s got quirks (more on those below), but stick with it and the car rewards patience more than anything else in the class.
For a broader look at getting started with setups in iRacing, see our iRacing setup guide.
How the Porsche 911 GT3 R (992) Drives
Understeer. You’ll notice it immediately in the mid-speed and fast stuff. The nose just washes wide. That’s 600-odd kilos of flat-six hanging off the back axle. Cranking on more lock only scrubs the fronts and makes it worse. Smooth steering, smooth brakes, smooth throttle. Honestly, smoothness matters more on the 992 than any other GT3 I’ve driven.
Slow corners, though. Slow corners are where the 992 earns its keep. All that rear weight plants the tyres under acceleration. I get on the power earlier in this thing than the BMW or the Ferrari, and the exit speed out of tight hairpins is silly. Slow in, fast out – the 992 in a nutshell.
Fast corners are sketchy. The rear swings like a pendulum, and any harsh input triggers snap oversteer, often with zero warning. Late in a stint when the tyres go off, those snaps get harder to catch. I’ve binned it at Eau Rouge more than once. You’ve got adjustable TC and ABS through the black box, and no manual clutch. Brake in a straight line, keep your hands smooth, and it’ll put down consistent laps. Bully it, though, and it bites back.

Setup Observations
iRacing’s stock setup for the 992 is honestly not bad. Probably top three stock setups in the GT3 class. You can hop in and be reasonably quick without touching anything. The McLaren and Mercedes stock setups are noticeably worse, for comparison.
Tyre pressures first. Set them to minimum cold and let them build during the stint. Target 1.50 to 1.55 bar hot – that’s what the fast 992 drivers on the forums are running. Go higher and the rear starts moving around mid-stint – exactly what you don’t want from a car that’s already getting tail-happy as the tyres wear.
For balance, go to the ARBs first. Stiffer front, softer rear. That gives you rotation to offset the built-in understeer. Small moves only. One click, drive three laps, see what changed. Going two or three clicks at once just muddies the feedback.
The aero map on the 992 is a bit odd. Higher percentage means more front downforce, which reduces rotation. Counterintuitive, but that’s how the garage displays it. Took me a few sessions to figure that out. Front splitter and rear wing are both adjustable, but tiny changes shift the balance more than you’d expect. Dead easy to overcorrect.
TC at 4 or 5 for grippy tracks, bump it up on slippery surfaces or in the wet. The Porsche’s TC is well-calibrated, so no need to get extreme. Brake bias in the 53-55% front range covers most circuits. Weight transfer is the thing with the 992. Every pedal input, every steering correction, shifts that heavy rear end around. Your setup should help you manage that mass, not fight it. One change at a time, test it properly, move on.
