you should change this mount also, i ll do in the near future.
it recommended as you ll have more vibrations then, after fitting the "hard" engine mounts.
Vibra Technics has 2 series, street mounts and competition mounts, and bailey just has 1 series or? I think there are some diffs, the street series are much smoother, i suppose, I can't really tell as I ve the comp. series.
