Hands down, this is the best part I have ever put on a car. I am 60 years old, so I have put on a few. I was always disappointed in my 2013 R Design as I felt the suspension was too stiff for the chassis. There was an annoying noise from the interior panels in the rear and I was close to pulling the back seat and the panels to try and quell the noise. This brace cures all of that noise and the rigidity is noticeable even at low speeds. Even standing still the whole car feels rock solid and I swear the stance even looks better. I still have not tested it over about 35 miles an hour and I am totally sold. Can't wait to wring it out on some curves at higher speeds. Installation was fine, took about an hour.
