Unsettled over kerbs
The car is fine on smooth tarmac and awful the moment a wheel is disturbed. That's wheel-movement damping and ride height, not spring rate or bars.

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.
- 01Take less kerb, and cross it squarehalf the kerbtechnique
A kerb taken at an angle lifts one wheel and twists the car. The same kerb crossed square barely disturbs it.
You may give up a little line. Almost always cheaper than the moment it prevents.
- 02Leave the exit kerb alonehalf a cartechnique
An exit kerb unloads the inside rear exactly when you are asking it for traction, and the wheelspin that follows costs more than the tightened line saves.
Costs a little exit width. Worth it in anything with limited rear grip.
- 03Softer fast bump damping1–2 clicksdamper · adv
Fast damping controls wheel movement, not body movement. If the car is fine on smooth tarmac and awful over kerbs, this is the knob.
Vaguer body control if you overdo it.
- 04Stiffer rear springs or ride height upone stepplatform
Stops the floor bottoming and stalling mid-corner, which is what makes a car feel random rather than loose.
Costs rear mechanical grip in slow corners.
- 05Check bump stop gap—platform · adv
If balance changes abruptly at one speed or over one crest, you're hitting the stops rather than running out of grip.
None — this is diagnosis.
- 06Softer rear anti-roll bar1 clickbar
Rear rolls and builds slip angle rather than snapping. Also keeps load on the inside rear on exit.
More roll; slower direction changes.
- 07Softer front slow bump damping1–2 clicksdamper
Front loads earlier in the dive, so the tyre has grip at the moment you turn in.
Transient only — won't help at the apex.
