So I got the rear motor mount installed today and wanted to post some thoughts in case someone didn't see it in the other threads.
first impression when I got the mount was how nicely it was built. I kept wanting to hold it because it just looked so damn good.
install was a little bit more challenging then I anticipated. I had already taken the mount out in the past when I installed the fswerks poly insert so I figured this would go quick. two things went wrong. the first was completely my fault. I didn't check to make sure I had the necessary tools before starting, newb mistake. getting everything out is easy, the mount it self has 1 15mm bolt and then it attaches to a bracket with 1 15mm bolt and the bracket has 3 15 mm bolts. you have to take the bracket off first and then the mount slides out. Well the Cobb mount comes with a new bolt that replaces the one where the mount attaches to the bracket. the new bolt is a 3/8 allen head bolt. I apparently did not have that size. luckily I own a bicycle and a parts store is right up the street so about 20 minutes later I had what I needed. the second issue was the mount itself. where the old mount slid in and out no problem, the new mount did not want to go in. I was worried for a minute that it was to big and wouldn't fit. what I wound up doing was spraying the area with wd40 and put a pad on the mount and tapped it with a hammer until I got it to slid in. after that, it was easy sailing, just bolted everything back up and good to go.
so for those installing this mount, heads up, you will need wd40 and a 3/8 allen head socket. and patience. it will go in!
So I've only put about 40 miles on it but that was a mix of city driving, hilly country road driving and highway and I got to say this thing feels damn good. I bought it initially because the stock mount with the insert alowd to much engine movement under hard acceleration which was causing my header to tap on the front sway bar. This mount completely got rid of this. there is zero wheel hop and to be honest the car just feels smoother. I thought the fswerks insert made a big difference but this is night and day. as for vibrations, call me crazy but I honestly think it has less vibrations now then it did with the stock mount/insert. there are still vibrations, don't get me wrong but it very little. this mount is smooth. I would definitely recommend it to anyone wanting a upgrade. Cobb knew what they were doing when the built this for sure.
