I am glad I did this upgrade
I have a 2011 Mustang and installed mine tonight. I had some difficulty getting the bracket onto the rubber insert, due to its close proximity to the driveshaft. My wife sat in the driver's seat and pulled up or down on the shifter handle, which helped me a lot. I am an aerospace product Engineer, and could tell this was quality material and great design. I used the black/stiff insert, partly because it comes with a split which made installation easier. My test drive was a real "wow". Before the change, I often missed the 2-3 shift under hard acceleration. Flawless tonight. I am glad I did this upgrade.
