Pausing Wheelcollider movement

[Luci85]

I’m working on a racing game, but I’m using sort of indirect movemente control. The player doesn’t change the driving direction through direct input, instead he draws a path in a planing phase, which the car follows in a racing phase.
Planning and racing phases switches multiply times in the course of one track. My problem is that I must pause every movement of the car (rigidbody with 4 wheelcolliders attached), but don’t let go of the direction and motortorque already applied.
I already tried time.timescale, but that stops my planning phase timer from moving.
