Mazda MX-5 Cup · Oulton Park · T1 Old Hall
Spins up / snaps on exitOversteer family
Fixed setup. The garage is shut for this car. The order below is unchanged — what would work still would — but anything you cannot reach is greyed where it stands.
T1 Old Hall — Quick, committed, and the road falls away on the way out with a wall waiting.
Technique — Turn in earlier than feels right and let it run wide on exit. The drop unloads the rear just as you open the throttle.
Rear tyres are asked for cornering and acceleration at once and run out. Give the rear more grip, or make the axle behave more as one unit.
Spec car with a shut garage: the ranking is technique only, because nothing else is available; traction-limited, so diff and rear grip move up; high speed, so aero is live here.
  1. 01
    Feed the throttle over a count of three3 countstechnique

    A rear tyre near its limit will take a lot of torque delivered gradually and very little delivered at once.

    None. This is free, and it is faster than the correction it prevents.

  2. 02
    Later, smoother throttle½ secondtechnique

    Getting on power before the car is pointed is the most common cause of this and costs nothing to fix.

    None — try this before any setup change.

  3. 03
    Get the car straight, then commit⅛ turntechnique

    Every degree of steering angle is grip the rear is spending on cornering rather than on putting power down.

    None — the cheapest fix on this list.

  4. 04
    Short-shift out of the slow corners1 geartechnique

    A taller gear delivers the same power with less torque at the wheel, which is exactly what a rear tyre with no grip left needs.

    Costs a little acceleration if the rears were never the problem. Test both.

  5. 05
    More drive diff lock5–10%diff

    Ties the rear wheels together under power so the unloaded inside wheel can't spin up and pitch the car.

    Fixed-setup car — nothing in the garage is adjustable.

  6. 06
    Softer rear anti-roll bar1 clickbar

    Rear rolls and builds slip angle rather than snapping. Also keeps load on the inside rear on exit.

    Fixed-setup car — nothing in the garage is adjustable.

  7. 07
    Softer rear springsone stepspring

    Lets the rear squat and put weight over the driven axle on power.

    Fixed-setup car — nothing in the garage is adjustable.

  8. 08
    More rear wing1 clickaero

    Rear downforce grows with speed, exactly where high-speed instability lives.

    Fixed-setup car — nothing in the garage is adjustable.

  9. 09
    Lower rear tyre pressure0.5 psityre

    More rear contact patch — provided the rears aren't already overheating.

    Fixed-setup car — nothing in the garage is adjustable.

  10. 10
    Higher traction control level1 leveldriver

    A stopgap while you sort the mechanical side — protects the tyre over a stint.

    Fixed-setup car — nothing in the garage is adjustable.
