Porsche 911 GT3 R (992)

GT3 · Rear-engined · Twin-turbo flat-6 · Downforce 3/5

The only rear-engined car in the class and it behaves like it: huge traction on exit, a nervous rear on entry, and a high skill ceiling.

Where to start. Everything is entry. The rear-engine weight bias means entry stability is the problem to solve and traction is the reward.

Symptoms this car reads differently

These notes appear alongside the ranked answer whenever you pick that symptom.

Rear steps out on entry

Rear engine puts the mass behind the axle. On entry that mass wants to keep going — coast diff and bias matter more here than on any other GT3.

Spins up / snaps on exit

Traction is this car's advantage. If you're spinning up on exit, something is genuinely wrong — check the rear tyre window first.

Won't turn in / pushes on entry

Rare in this car. If it won't turn in, suspect you've over-corrected the entry instability with too much coast lock.

What this car's answers lean on

In order: what this car reaches for first when something is wrong. GT3 sets the baseline, and anything this car weighs differently says so.

1. Differential and engine braking more than the archetype
2. Braking system — bias, ABS, pressure more than the archetype
3. Anti-roll bars
4. Free changes — driving, not setup
5. Tyre pressures
6. Damper clicks more than the archetype
7. In-car driver aids and gearing

What you cannot change on this car

Still shown, struck through at the rank they earned — partly so the list is honest, partly because they open up as you move up a class.

Shorter gearing

Gearing is fixed on this car.

Stiffer heave / third spring

No third spring on this car.
