Bought because of the promotional claims. I have a 2001 Mercedes Benz S-430 in absolutely superb condition. mechanical and more. Unfortunately, the product, the driver's side A-pillar, did not live up to expectations. My car drove like a dream even when I ordered a new strut as the passenger side strut was replaced less than a year ago for $385 plus $120 for installation and I figured I'd replace it until it gets built . I thought it was a good deal as this device cost about half as much and met the same specs on paper. This is where the comparison ended on paper. Just got back from home after riding 800 miles in Utah. I felt like I was driving a 1911 Ford pickup. (These pickups had no struts or shock absorbers). This S-430 has always been like a cloud. Now it isn't. If you want a really tough ride, buy these racks. I am so disappointed. I only had 27 days to return this item. Of course it's gone. I'll eat this product, buy another $385 stand and replace this one. Unless the trip means nothing to you, I hope you make the right choice! Updated 07/25/18. Well the product has never been driven in easy mode since it was installed, it only drives in cornering mode (hard) which causes the workshop visit warning to fire every time I start the car. I will buy and install a better product (cost wise) and let you know how it works. I wasn't thrilled with Autosaver88's products. See my review of their air compressor for this system. 11-6-18 is just a note to say the new rack works just as well as the OME rack. I have just returned from a 2500 mile trip. It's like you're flying on a cloud again.
