Why is my iRacing car loose on corner exit?

By Shane Lowry · updated 2026-09-28

The short answer

Most of the time it is your right foot, not the setup. Loose on exit usually means throttle applied earlier or harder than the rear tyres can take while the weight is still transferring. Smooth it on and it usually goes away. Only once your inputs are clean does the car become the suspect.

Identify the beast before you touch anything

Loose (oversteer) is the rear stepping out mid-corner or on exit. Tight (understeer) is the front pushing wide while you crank the wheel and nothing happens. Watch your replay and feel the wheel. Do not guess.

The first instinct is to open the setup screen. That is the last thing you should touch.

Check the driver first

Before you change a click, ask whether you are asking the tyre to do something it cannot.

Then, and only then, the car

If it is still sliding once your inputs are clean, small changes go a long way on modern tyres:

Loose: add rear wing if the car has it, soften the rear anti-roll bar one click, or add one click of rear rebound damping.

Tight: soften the front anti-roll bar one click, or add one click of front rebound.

One change at a time, five laps, revert if it is worse.

Nine times out of ten the fix is your right foot or your hands, not the car. If you are still lost after that, ask — that is what a coach is for.

Where this comes from: this answer is drawn from section 21 of the Taming the Wiggle: Oversteer & Understeer Correction — part of the BustaWrench Guide, 57 plain-English sim racing and setup lessons.
