            great upgrade for the s550

            car turn flatter and less body roll with this rear bar. great upgrade if your dont like that cadillac feel in the turns. just a note ride will get stiffer with bigger sway bars, its not huge difference but its noticeable.

            Major upgrade for v6 ‘Stang

            My ‘15 V6 comes with a 34mm front bar and hollow 20mm rear bar. This is a solid 25mm bar with three end positions possible. I did a couple of track days with the stock setup recently and the OE setup gives massive understeer (it plows badly). Installed the Eibach bar easily and have just been doing street driving with it so far- on middle position the car feels radically different already. The loads are not all stacked up on the outside front tire in corners. We’ll be back to the track next month and will update then. The OE V6 chassis setup is heavily biased toward “safe” understeer and if you don’t have a powerful engine, you can’t really use throttle to shift the load around. If you like to play with the corners, and you car came with the wimpy rear bar, this is a must-do mod. The instructions specify the stiffest setting is for “dry, track use” and that is best taken to heart. I can feel the car may be a bit tail-happy if I go stiffer. Good to have adjustability!!

            An essential upgrade.

            I recently bought a 2015 V6 and I thought it felt like it was "floating" at highway speeds. A bigger rear sway bar seemed like a good fix. Not only does the car now feel great on the highway, as an added bonus the cornering feels far better than I expected. Truly amazing! Easy install and excellent Eibach quality. Highly recommended!

            Great investment

            I have a 16 gt base, just recently installed this eibach rear sway bar and the car hugs the road. It makes a huge difference, I would definitely recommend this to anyone who wants to improve their handling. But don't take my word for it, go put one on and tear up the streets.

            Great product.

            Super simple! I love the way it takes corners and handles while I drive!
