I installed this brace on a Monday and removed it by Friday. Mercedes mastered suspension and the brace takes away handling regardless of what they advertise. When taking highway ramp a high speed with 2014 c350 4matic, it felt like inside front wheel wanted to lift kinda like 3 legged elephant. I-695 heading west ramp going northbound on I-83. $300 and not impressed. I installed it to try to stiffen up chassis and get rid of glass knock sound of panoramic roof. It didn't fix the noise and I felt it undermined the stock suspension. If anyone has solved the glass knock sound of this roof, please contact me. For sale now if anyone else like to try the bar. Maybe I am missing what it is actually supposed to do but I didn't notice any improvement. Mercedes better be able to find a fix because my car has 35,000 miles on it and had this knocking sound for a while. Anyone interested in class action suit, let me know cause I have to probably live with it for the rest of this cars life. I like the car but hearing a loud glass knock sound every once in a while just ruins the car
