Porsche 911 RSR

The mid-engined 911 RSR: its naturally aspirated flat-six sits ahead of the rear axle, unlike a road 911. Strong traction once pointed; endurance discipline matters as much as one fast lap.

Brake straight, release cleanly, rotate once, use the traction out.

Symptoms this car reads differently

Steps out on entry

Mass behind you. Abrupt release steps the rear. Bleed into the turn.

Snaps on exit

Traction is strong when straight. Not when the wheel is still wound on.

Falls off over the stint

Rear tyre life over a stint. Smooth is fast.
