How long does the break in usually take? Im at about 250miles right now gotta say i love the crisp feeling . I am from Hawaii and summer isnt really friendly I like to take advantage of having A/C and I was wondering to those who have broken in their motor mounts how was it compared to the break in process? I am a bit worried and I expected the vibrations when the a/c is on but im just wondering if it will tone down a bit more. I downloaded seismometer for the Iphone and I will be posting some pictures tomorrow morning.
