On-power (corner-exit) oversteer — loose under throttle

The rear breaks loose when you get back on the throttle out of the corner.

Try these in order

Make one change at a time and re-test — that's how you learn what your car likes.

1. 1
   Thicker rear diff fluid

   Smooths how power hits the rear tires so they hook up instead of spinning.

2. 2
   More rear toe-in

   Stabilises the rear under drive.

3. 3
   Softer rear springs / thinner rear oil

   Lets the rear squat and plant under power.

4. 4
   Softer rear tire or fresher compound

   More mechanical grip where you're losing it.

5. 5
   Smoother throttle — gear up slightly or soften ESC punch/throttle expo

   Less initial hit = less wheelspin.

6. 6
   Increase anti-squat (if adjustable)

   Helps the rear plant under acceleration.
