My car has these two round thing mounted on the frame of the car, under the engine in front. One is blue and one is rusty, they dont seem to do anything and I was wondering what they are. I posted a pic in the album (that isnt my car, its someones 6000 from cardomain but i couldnt find a better pic to describe it). See on either sides of the soda bottle, the round things, what are they?

Lets see if this worked.....

If I see them right, they are the rubber mounts for your subframe. The subframe usually includes everything forward of the firewall. If you look at older RWD cars with "body on frame" you will notice the whole body sits on those round rubber things. This is just to reduce vibration and give it a smoother ride.

BTW... your picture didnt post right just above...
