Only if they are broken or you planto uprate them
The engine should move slightly when revving but not much and if its moving back left, it
could mean the ECU engine mount has broken.
The mount is in two parts, held together by a long screw if I remember rightly.
Have the car on level ground, stick a jack under the sump (use a block of wood) to support the engine and unbold the mount to see if it's broken.
