Corner Lab

Pushes at the apex

Mid cornerUndersteer family

Steady-state, so this is a mechanical or aero grip split, not a damper problem. Dampers will not fix this.

Ranked on a free car

This week's rookie circuit is free — these labs open with this symptom at its key corner, already ranked. What is free this week.

The default order

Generic order — open a lab for your car and corner.

  1. 01
    Softer front anti-roll bar1 clickbar

    Lets the front axle roll and build slip angle, adding front grip as the car takes its set.

    Slower initial response; more roll to wait through.

  2. 02
    Stiffer rear anti-roll bar1 clickbar

    Takes rear grip away to shift balance toward rotation.

    Check exit traction afterwards.

  3. 03
    Lower front tyre pressure0.5 psityre

    Bigger front contact patch. Verify against carcass temps rather than guessing.

    Fronts run hotter and fall off later in a stint.

  4. 04
    More front negative camber0.1°geo

    Keeps the loaded front tyre flat at full roll. Only helps if the outer shoulder is running hot.

    Weaker straight-line braking.

  5. 05
    Softer front springsone stepspring

    Front grip, plus a lower nose under load which adds a little front downforce as a bonus.

    Watch you're not bottoming the splitter.

  6. 06
    More rake — raise the rear1–2 mmaero

    Shifts aero balance forward. Only meaningful where there's real speed.

    Looser at the rear in fast corners.

  7. 07
    Slow the entry, wait for the car5 km/htechnique

    Overdriving the entry saturates the front tyre into understeer you cannot unwind before the exit.

    None — costs nothing to test.

  8. 08
    Open the wheel and wait for it⅛ turntechnique

    Mid-corner push is a front tyre being asked for more angle than it has grip for. Less angle is more grip, and the car comes back to you.

    Requires trusting the car for about half a second. That is the hard part.

  9. 09
    Hold one steady input1 inputtechnique

    Sawing at the wheel through a corner never lets the front tyre settle at a slip angle, so it spends the whole corner somewhere below its best.

    None. A quiet wheel is faster almost everywhere.

  10. 10
    Use the full width on entry1 car widthtechnique

    A wider entry makes the corner's radius larger, which is the only way to ask less of a front tyre without going slower.

    Needs the room to be there. Check your mirrors first.
