They work as advertised. The smaller bushing is a little bit of a pain to snap into position. Once installed, you never have to fight with the shifter to get into a gear. It always clicks into place very easily. Worthwhile mod!
This was by far the easiest upgrade to do. Took me longer to jack up the car and take the protective shield off the bottom of the car than it did for this. Defenitely notice an immediate improvement in the way shifting feels.
