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 the 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 straight line 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 half inch
impact with my 21-millimeter socket.
And I did use a hammer to get that bolt out.
Alright, so the first step to getting those links in is to get our wheels off.
So with the 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,
[inaudible 00:06:01] little vent here in the way.
We'll just snake 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 snake 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 doesn't 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, 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 boat here we're
going to 85-foot-pounds, 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 americanmuscle.com.
