Really well built, strong materials and perfect fit and finish. I am using the softest bushings they provide and the difference in response is incredible.
These aren't as annoying as full solid mounts but they do add a lot of NVH if that is going to bother you. I have to say though, after doing all of the other drivetrain-stiffening mods, this is by far the most impactful one. If you don't mind more NVH, skip all the little stuff and just go trans-mount, pitch stop, and this mount and you'll be very happy
Note: pay attention to how you orient the post on the center piece when you are building the mount itself before install. I got through the entire process but realized the posts didn't line up on the frame of the car because I installed the left insert onto the right-side mount and vice-versa. don't be like me and do it right the first time haha.
