Well installed it in the driver side and must say WOW!!! I dunno if it's the mount or not but htis car feels better. The motor sits still. Also decreas my cruising on the highway knock.. I use to get like 15-25KR cruising at 65mph and now the highest it goes is like 4 but usuallly stays at 0.... I highly recommend it.... You do feel a slight vibration but the ride makes up for it...
