255/35 Fronts - 275/35 Rear upsets VDC
Fronts on 9.5" rim
Rear on 11" rim
Tyres are Toyo R888R
According to VDC Happy calculations the OD difference is 2.2% which suppose to be fine,
What can be the problem ?

If you're running 35s on 18s, it's possible the whole combination is upsetting the ECM because wheel speed is higher than factory heights. Not probable but possible. If 19s, you should be good.
Did this just happen right AFTER you made a change or was it OK for a while then went South? If latter, possibility is that one or more of your wheel speed sensors has gone awry.

More info
Now after some testing i can narrow it to 1 scenario that happen all the time:
VDC ON or OFF (no effect)
When turning right while braking (tail braking)
The car is applying ABS
It is not happing when I'm turning left with braking or turning both directions without applying brakes at all.

Steering angle sensor is probably out of adjustment. The system works with VDC on or off, that’s why mine is 100% disabled on my track car
