We took our employee’s 2013 BRZ out to the shop to install the Whiteline Front Roll Center Adjustment Kit for the 2013-2014 Scion FR-S and Subaru BRZ. So we looked online to find the installation instructions and decided we would make a fairly comprehensive write-up for you!

Going into this, pressing the ball joint out and back in seemed a little difficult, but once we got started, they pressed right out, and right back in. Guess that’s the beauty of having a new car to work on  . Before we get started let’s see what Whiteline has to say about this product:

Roll Center Kit incorporates 2 steering arm tie rod ends and 2 ball joints and is designed to raise front roll-center geometry after lowering the vehicle and also improve on the original bump-steer geometry. Changing front suspension geometry by raising roll-center, results in substantial increase to roll resistance and significant reduction of suspension compression of outside front wheel during cornering through improved weight transfer distribution. Whilst bump steer correction via extended tie rods aids in minimizing steering angle input during suspension articulation.
So we looked around the shop and found that the only thing we didn’t have was the press kit to press the ball joints out. So every other tool we needed was just laying around to make it easy on us. Here’s what we ended up using.

Keep in mind; you will have to get your car off the ground, securely on jack stands and front tires/wheels off the car to do this installation.

1) ½ in drive ratchet
2) Extensions
3) 17mm, 19mm sockets
4) Vice grips (for that pesky cotter pin removal)
5) Needle nosed pliers
6) Flat tip screw driver (small)
7) Drill with 10mm driver and 12mm driver (for removal of under tray)
8) Pickle fork
9) Hammer
10) Impact (not necessary, but makes things easier)
Here’s a picture of most of the tools we used. We didn’t use the pry bar, but it made it into the picture somehow.

Ok, now we’re getting somewhere. Since we didn’t have the press toll required to press out the bushings, we ran down to Autozone and grabbed one of these, it worked great!

Now that we have all of the necessary tools, let’s get started. First thing we need to take off is the under tray of the car to gain access to the bolts to take the lower control arm off. It’s simply 8 12mm bolts, 4 10mm bolts and 6 plastic clips and it comes right off. Be careful as it might just fall off when you get the last bolt loose.


To get the clips off, simply slide a small flat tip screwdriver in the head and pop it out and it should slide right out.


There are five nuts/bolts that need to come off to get the lower control arm out. Some are 19mm and some are 17mm you see which is which once you get started. Here’s a shot of the control arm from below that shows you roughly where they are.

Bend the cotter pin as such that it slides out from the hole.


Now take the castle nut off.

Now that the nut is loose, just tap the top of the ball joint being careful not to damage the threads, and it should pop right out.

Now we can move to the front of the car and undo the bolt and nut that holds the front/lower control arm bushing in place.

Pull the pin out of the ball joint that connects to the hub spindle.


Then, simply break the nut loose and thread it off.

Now take your pickle fork and spread the ball joint loose. This shouldn’t take a whole lot of effort.

Now we can move on to the rear bolt/nut. Just get a ratchet on one end and wrench on the other and it should come right out.

We loosened the tie rod end locking nut while it was still installed because it will be a lot easier to to it on the car, than trying to hold it while doing it off the car

We took our sharpie to mark the threads on the tie rod to make sure we got as close as we could to factory specifications when reinstalling the new tie rod ends.

Now that we have it loose, let’s go ahead and pull it out. The whole assembly is now ready to come out of the car.

Just wiggle it a little bit and it will come right out.

Then we threaded the tie rod ends off and grabbed out new Whiteline replacements! Man, they look good. You can definitely see the height difference from stock to these replacements. That’s what it’s all about!

Installation of these is extremely simple, just thread them back on the tie rod in place of the stockers keeping in mind the marks you made on your threads to line them up as close to factory specs as possible.


Phew, now the fun part begins

First thing you need to do before removing the factory ball joints is getting the dust boot off. Just take a flat tip screw driver and work your way around the boot prying upward and it will come off. There will be quite a bit of grease when you get it off, just wipe it off with a rag.

After that’s done, we can take the ball joint tool out of our press kit and press the old one out, we had the #2 sleeve on the bottom with the ball joint tool and the #3 sleeve on the top to press it out. It worked pretty slick. It seemed like it wasn’t going to work at first, but it slowly worked right out. Be patient here.

Now that we have the old one out of the way, let’s press the new one in. this is VERY simple; pull it through from the bottom like this

Now put the #2 sleeve on the bolt side and press it in straight on the ball joint itself. Be sure to press it all the way in, there shouldn’t be any gap

Here we are placing the assembly back onto the car. It seemed to be easiest to slide the forward most bushing in place first, and then slide the rear one in, then work on the ball joint into the spindle.

Line up the hole in the rear of the control arm and slide the bolt in and thread the nut. Don’t tighten it down just yet.

Take your front bolt/nut/plate and replace them in the front position, keep these loose as well (for now)

Then slide the ball joint into the hub assembly might be slightly tricky, but it will slide in.

Place the tie rod end in the rear of the spindle.

Thread on all respective nuts and tighten them to factory specifications.

You can replace the under tray and you’re ready to go! That wasn’t so bad, was it? Now you can enjoy the benefits of having the Front Roll Center Adjustment Kit installed! Get your car on the track and experience the difference this product makes in handling!

 

Thanks,

Corby
