Installed for all of 3 hours. I immediately knew it wasn't for me, and uninstalled it. it's in practically brand new shape.
Here's the deal:
This thing is amazing for people that track their car a lot. It's great for a dedicated race car. It's great for anyone wanting a very raw feel to the car, and its effect on decreasing driveline slop is super noticeable.
If you're like me, and actually prefer things relatively quiet, and primarily daily drive your car, it's NOT for you, and I recommend you do not buy it.
