Another suggestion would be to check your transmitter settings and reduce your steering rate/speed and exponential. Run negative expo if anything but spectrum and if spectrum run 20 to 30 positive.

A mini needs you to drive smoothly and not wrench the wheel or sticks left tor right.

From your limited details. Solutions:

Run a harder front spring, stand the front shocks up, use a spacer on the front hex. This will make the car more stable.

Rear run a softer rear tyre, softer rear oil, run a 5mm or 4 mm hex. Narrower rear should give more rear grip.

Because you have not included all of the data it is very hard to give you a full solution.

Ride height front and rear?

Droop or shock length etc.

Did you remove the front bumps under the front arms, these will rub and cause issues if not removed as they will drag on the ground with weight transfer. I have observed this mistake on another persons MO5 V2 and this was the issue. The instructions do not tell you to remove it, as the front arms are universal. I cut mine off and only fit left and right.

Anyway consult a mini driver at your local track as advised by others here.

I certainly do not know much but the above have worked for me in the past.
