Installed the Pedders bars and these end links last weekend, huge improvement, and they are quiet as advertised. I did have issues with the lack of instructions included with the parts, and the incomplete ones on Pedder's website... One example is these end links don't require drilling the existing mounting holes on the car as described in the online instructions, didn't discover that until after drilling.
Good product though.
