I have about 3500 miles on my ms3 and recently installed the AWR rear engine mount 70 durometer. After installing it I noticed that when the car is idling if I turn the steering wheel the engine actually very slightly revvs. I do not know if it is due to the engine mount(dont see how it is) or if I actually just started listening closer due to the new part(making sure there werent any insane vibrations or noise). I was wondering what could account for this? Sorry if I seem like the noob I am.
