How do I get more traction on corner exit?

Wheelspin off slow corners — especially the inside wheel — is usually the power side of the differential too open: add lock to tie the rear wheels together and put the drive down. If the rear loses contact over exit kerbs, soften the rear springs or anti-roll bar; if the car is still rotating as you open the throttle, you're catching a balance problem with traction — fix the rotation first. And an overheated rear has no grip to give, so check the thermal trace late in a stint.

Why does my inside wheel spin out of slow corners?

With an open or lightly-locked differential, the unloaded inside rear wheel spins up under power while the loaded outside wheel does little — so you get noise and no drive. Adding power-side lock forces both wheels to turn together and deploys the torque through the tyre that actually has grip. Too much lock, though, makes the car push wide on exit.

Is exit traction a diff or a balance problem?

Both feed it. The power differential decides how the drive is shared between the rear wheels, but a rear that's too stiff, too low or overheated has no grip to deploy regardless of the diff, and a car still rotating at the throttle will spin whatever the diff does. Engineer the platform and balance first, then trim the diff.

What an exit-traction problem actually is

On exit the car is accelerating and light at the front. The rear has to put the power down through two tyres that are also cornering. If the differential won’t lock under power, the inside rear spins up and you lose drive; if the rear is too stiff or the tyres are overheated, there’s no grip to deploy; if the car is still rotating, the throttle finishes the slide.

When wheelspin becomes a sudden bite — see snap oversteer.

How the engineers diagnose it

Lost drive on exit has three usual culprits — the engineers separate them:

Power differential — wheelspin off slow corners, especially the inside wheel, is the power side of the diff too open. More lock ties the rears together and puts the drive down; too much makes it push wide.
Rear platform — a rear too stiff (springs, ARB) or too low loses contact over exit kerbs. Soften it to keep the tyres planted as you feed power.
Rotation and thermals — if the car is still rotating at the throttle, you’re catching a balance problem with traction. And an overheated rear has no grip to give — check the thermal trace late in the stint.

Exit traction pays on every straight that follows a slow corner — it’s the cheapest lap time there is. One change, three laps, watch the throttle and wheelspin traces. See the glossary and the setup guide.

The levers that cure an exit-traction problem

From the diff outward — the power differential first, then the rear platform and thermals:
