Oh my goodness. Quite honestly, this has given me the best return on investment I've made to my car.
That said, I didn't simply purchase and install. I didn't completely follow suit with the modification. Instead of cutting off the center section or drilling a hole in the center of it. I decided to cut out a square in the middle of the center section. I left approximately 5/8" on both "sides" (where the lip ends) and approximately 17/32" on both ends.
I don't have anything to compare it with, but this is exactly how it should have been from the factory. There is a slight vibration @ around 2800 rpm. Definitely not anything to make headlines with. The slop plus gone. Again, my favorite addition to date.
