      Video Review & Installation

      Justin: If you're looking to correct negative camber on your lowered 2015 and newer Mustang while also improving things like handling and launching performance, then you should definitely consider a set of the BMR Rear Upper Control Arm Camber Links that we're talking about here today. Now the BMR Uppers will combine a durable T6 billet aluminum construction with a combination of Delrin bushings along with spherical bearings all for the mid $300 price point. Installation won't be terribly difficult but will require the removal of two rear wheels so therefore the site will nudge this up to a soft two out of three wrenches on the difficulty meter and a couple of hours or so to complete from start to finish, as we'll show you guys a little later in the video.So as the name implies, control arms play a vital role in your Mustang suspension by controlling or essentially limiting the movement in your Mustang's rear end. Now with the older four-link cars, SN95s, things like that, you had two uppers, two lowers. Now with the S197, you had a three-link which was two lowers, one upper and a Panhard bar. Now with the IRS-equipped S550s, you got all kinds of stuff going on, right? You've got your vertical links which essentially act as a lower control arm, you got rear tow links, lateral links or camber arms which these will replace and then there will be a host of smaller but equally important parts such as your IRS bushings, in addition to your cradle bushing lockouts.And like all factory parts, those suspension components are historically loaded with soft rubber bushings from the factory which are great for the masses because they're gonna provide a quiet and comfortable ride. But for the enthusiasts out there looking for all-out performance this soft rubber is the enemy because it leads to deflection which leads to things like poor handling, poor traction, and that dreaded wheel hop.Now the upper control arms or camber links here from BMR are gonna address two different things. First and foremost, they are gonna help increase your ability to corner and launch harder thanks to the superior components, but they're also gonna help lend themselves to correct your suspension geometry on lowered Mustangs as they are a bit physically longer compared to the factory arms, which by the way those factory arms don't allow for proper correction once the car has been lowered. BMR goes on to state that guys out there who are serious about drag racing with their IRS-equipped S550s, these guys here will help you achieve a zero camber setting in the rear end which really is going to be ideal for straightline traction in drag racing.But let's touch on that superior build a little bit more and again, guys, there's really no comparison between the BMR stuff and the factory part you will be replacing. The BMR arms here will be CNC-machined from high-quality billet aluminum and then finished off in an anodized black. Now at that point, one end receives the durable Delrin bushing which is gonna be a bit firmer compared to your more traditional polyurethane stuff. The other end, guys, features a solid spherical bearing and when working together, these two will all but eliminate the factory deflection while still allowing for acceptable NVH levels and ride quality. Now the Delrin bushing is gonna be fluted on the inside. Basically, that means all that grease that you do grease this thing with from time to time will prolong the life of the bushing itself but also keep things a little bit more quiet at the same time. No squeaks or any noises, things like that. Everything is built right here in the USA and will be backed by BMR's two-year limited warranty against any possible defects.Now, I do wanna point out that BMR does offer other options with these arms, including combinations of polyurethane, Delrin, full spherical adjustable options, that's one thing I really dig about the company, they give owners out there a wide variety of parts to better suit your driving style and your needs. Now with that cover guys, this is the time in the video where I stop yapping and show you all what it takes to get these installed on your S550. So hang out for a bit, here is our detailed walkthrough along with a quick tool breakdown.Man: Tools required for this install: a torque wrench, a ratcheting 18-millimeter wrench is very helpful, 15-millimeter wrench, a 3/8 drive with an 18-millimeter socket and an extension, optional is gonna be this air ratchet and to get my wheel off I did use a 1/2-inch impact with my 21-millimeter socket, and I did use a hammer to get that bolt out.All right, so the first step to getting those links in is to get our wheels off. So with our wheel and tire off we're gonna take an 18-millimeter socket and place it on this nut right here. We're gonna take a 15-millimeter wrench and grab the bolt head, I'm gonna go ahead and take this out of here. Then we're just going to push this bolt through, I'm gonna grab a hammer, and to always be safe to protect those threads, let's start that nut back on there, just give it a tap. And to help back it out I'm actually going to put a 15-millimeter socket on here and use my ratchet to get this out of here. Last couple threads here.Now we're gonna go after this nut right here which is an 18-millimeter. On the inside the 15-millimeter head is actually captured so there's a little tab that goes into the body so you don't have to worry about getting the tool onto that. This is an 18-millimeter ratcheting wrench, we're just gonna remove these. Let me see if I can get this by hand now, I'm gonna go ahead and push the bolt through, could get a little vent here in the way. We'll just sneak this out from the bottom.So let's go ahead and get our new BMR upper control arms in place. One important thing to note is this relief right here is going to be on the inside and that's just gonna make clearance for that CV shaft. Let's sneak this in here, put it in place, I'm gonna come from the backside behind the shock and the spring and get my bolt started here and go through. I'm gonna start my nut. Now I'm not going to tighten this down all the way because it does have a torque value of 85-foot-pounds, I'm gonna bring in my air ratchet here and just help tightening it up a little bit. All right. And I still have a little bit of movement here because I need to get my spherical end in, I'll slip that on now. Bring this down. And you do have to push up a little bit on that rotor to get that bolt started. Got a little bit showing, I'm gonna give it a little love tap and then 18-millimeter nut on the backside, and this has a 15-millimeter head. All right, so as you can see I brought a torque wrench in and for the inside bolt here we're going to 85-foot-pounds. All right, there we go. And for this outside one we're gonna go to 76-foot-pounds.Now I'm gonna get this wheel and tire back on but all those steps you just saw you can complete on the driver side to get that upper control arm in. That's gonna wrap up my install of the BMR Rear Upper Control Arm Camber Links for your Mustang S550. And for all things Mustang, keep it here at

      Improve Handling Performance. Get more responsive launches and sharpen your cornering stability by shoring up your lowered Mustang's rear suspension geometry with a set of BMR Rear Upper Control Arm Camber Links. Your stock arms aren't letting your lowered Mustang realize its full potential. However, BMR's non-adjustable Control Arms boast heavy-duty spherical bearings and Delrin bushings to put an end to deflection and suspension binding, giving you consistent handling in even the most demanding conditions.

      Remove Negative Camber. These BMR Rear Upper Control Arm Camber Links are primarily designed for lowered Mustangs that are looking to remove the camber gained from a lowered ride height. Designed to be longer than the factory arms, these BMR Control Arms allow you to correct/remove negative camber on lowered Mustangs. These Control Arms are not for those looking to GAIN negative camber. With an average 1.2-inch drop, the most negative camber you can achieve will be approximately -2.0 degrees. These BMR Control Arms work very well for drag racers who have lowered ride heights, and are looking for ZERO camber.

      Delrin Bushings. The included Bushings are precision CNC-machined from a high quality Delrin material for superior strength and excellent dimensional stability. Delrin is an extremely stiff thermoplastic that features a very low coefficient of friction making it the perfect material for performance automotive bushings. Complete with grease fittings, these Delrin Bushings are internally fluted for consistent lubrication to eliminate binding.

      Durable Construction. Proudly designed and manufactured in the U.S.A., these BMR Rear Upper Control Arms are CNC-machined from 6061-T6 billet aluminum for strength and light weight, in fact you'll drop 4 pounds of weight. BMR then completes their Control Arms in a durable black anodized finish for good looks and long lasting corrosion protection. The included heavy-duty spherical bearings are designed to stand up to high loads while offering bind-free suspension articulation.

      Bolt-on Design. BMR designed their Upper Control Arms to be an easy bolt-on installation using the existing mounting points, with no modifications required. Using just basic hand tools, installation can be completed in about 3 hours’ time. Please note that an alignment is highly recommended after installation.

      Two Year Warranty. BMR products are warranted to be free from defects in material and workmanship under normal use and service for a period of (2) two years from the date of sale to the original purchaser. Some exclusions may apply, please see manufacturer's warranty for details.

      Application. These BMR Rear Upper Control Arm Camber Links w/ Delrin Bearings are designed to fit all 2015-2023 Ford Mustang models. Sold as a pair.
