Porsche 911 GT3 R (992)

Rear-engined · Naturally aspirated 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.

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

Steps out on entry
Rear engine puts the mass behind the axle. On entry that mass wants to keep going — preload and bias matter more here than on any other GT3.
Snaps on exit
Traction is this car's advantage. If you are spinning up on exit, something is genuinely wrong — check the rear tyre window first.
Pushes on entry
Rare in this car. If it will not turn in, suspect you have over-corrected the entry instability with too much preload.
