Review & Install Video
The BMR Front and Rear Adjustable Sway Bar kit will be an excellent choice for the S550 owners out there who wanna dramatically reduce the body roll and alter the understeer or oversteer characteristics of the car for the mid-$400 price point. Now, prospective buyers can look forward to a 35-millimeter front bar, along with a 25-millimeter rear option, both of which are 3-way adjustable. Your install is gonna be pretty straightforward guys, but there is a small amount of work both underneath the car and through the engine bay here, so I am gonna knock this one up to a very soft two out of three wrenches on the difficulty meter with a little bit more detail later in the video.So BMR's goal as a company is to help you guys improve both your handling and your traction by offering owners a plethora of different parts to help increase or improve both areas. Now, the sway bars here are certainly more of a handling focused mod, and in true BMR fashion, the company has gone through great lengths in designing a set of bars for S550 owners to really wake up the handling performance and help eliminate excess body roll. Now, not only will this give you guys a little bit more confidence behind the wheel, but you're also gonna be able to set up the car for your driving style thanks to the adjustability. Now, guys, I am on record and I'll say it again here, these cars, in my opinion, are very much under barred from the factory, and that, of course, is to better suit the masses as opposed to the spirited driver like you and I. And BMR tends to agree with me on this as they claim the factory sway bars have a very low torsional spring rate thanks to the smaller diameter tubing. But let's talk about how these bars from BMR will be an improvement for both you and your ride, and honestly guys, you have a couple of different things working for you here. First up your diameter and also your materials. Now, as far as the diameter is concerned, you're going to be looking at a 35-millimeter front bar here in addition to a 25-millimeter rear bar. Now, according to BMR, the front option will be an increase in rate for stiffness ranging from 28% to 70% over the factory bar it is replacing. Now, the rear bar, on the other hand, is even more impressive with a 63% to 208% increase over the factory bar, and that big range on both bars is made possible, of course, thanks to the 3-way adjustability that both the front and rear have in common. But by upgrading the front and rear bars, the car will certainly feel more responsive overall, will definitely be flatter in turns thanks to the drastically reduced body roll, and at the same time, the car should rotate a little bit better through those turns as well.Now, this is going to be a welcome change for most owners out there because, in my opinion, these factory S550s have the slightest bit of understeering characteristic sport tendencies, meaning, the car just kinda wants to push or plow through turns. But with the bigger bars like the options we have here from BMR, you're going to experience more of a neutral balance with the car and maybe even experience a little bit of oversteer depending on how you set these bars up. Now, this just is simply accomplished by moving your end link to one of the three respective holes here on each bar, essentially softening or stiffening the bar in the process.Guys, listen, everyone has their own driving style, everyone's setup is going to be a little bit different so this is certainly one of those things you're gonna just have to play with a little bit before landing on your ideal setting. My advice to you, start with the end links on the middle hole here for each bar, make a few adjustments and go from there. But getting into the physical construction here with these particular sway bars, BMR is quick to point out a few key attributes. Now, for starters, these bars are manufactured from cold-form DOM steel tubing. Why cold form? Because according to BMR, the cold-form stuff is better at reducing or resisting torsional fatigue, and can actually retain the memory or shape better than most hot form bars.Now, the bars themselves are actually hollow, which does make for a strong bar overall, but one that won't add a ton of weight to your S550. Now, both bars do include their own dedicated brackets, as you can see right here, and loaded with an 88 durometer polyurethane bushing to be exact, which will help reduce deflection or movement far better than the soft rubber factory bushings. Finally guys, and not nearly as important, you'll notice we do have these things obviously in red here on the table with me for this video, but BMR does also offer these things in their signature hammer tone finish as well and you can find those on the site if you are interested. But what do you say we switch gears real quick here and talk about the install? And again guys, this isn't exactly the hardest job in the world, but since there is some work involved underneath the rear of the car in addition to some work involved to get the front in place, I am gonna knock this one up to a relatively soft two out of three wrenches on the old difficulty meter here, and tool-wise, you're gonna wanna consider a socket set in addition to a few allen keys, a number of extensions to help you get some bolts through the engine bay, some open-ended wrenches, and then last but not least, obviously a way to get the car in the air slightly. A lift would be the preferred method, of course, but you can always do jack and jack stands, or race ramps if you have access. Getting started, get the car up in the air and pop those front wheels off to give you better access to those front end links. At this point, you can remove those end links and hit the front sway bar brackets which I like to do through the engine bay. To do so, just chain a few extensions together or hit them through the wheel wells, whatever is easiest for you. With the brackets removed go ahead and fish out that factory front sway bar and fish in the new BMR option in its place. You might wanna have a buddy help you kinda work its way through its engine bay. Now, reinstall the new brackets from BMR in addition to your end links, reinstall the front wheels, grease those front bushings, and the front is completely wrapped up. Now, in my opinion, the rear bar is definitely the easier of the two, but go ahead and disconnect those rear sway bar end links, remove the brackets and remove the factory bar from the car. Reinstall the new BMR 25-millimeter option in its place in reverse order, and your installation is complete. The BMR Front and Rear Adjustable Sway Bar kit is gonna be a great choice again for the S550 owners out there who are interested in dramatically improving their handling, and you can find your set right here at americanmuscle.com.
