I was a bit skeptical installing these but I wanted to stiffen up the rear differential. I didn't have time to pull the diff and have the OE bushings removed so I figured I'd swap these in one evening after work to see how they would do. There is a noticeable increase in NVH and I have better feel of what the rear of the car is doing on track. These were definitely a worthwhile upgrade for performance but will make road trips a little less comfortable.
