We miss you, Matt! Fortunately your videos will live on forever.

Miss you guys too 😢 ❤️

Some spicey looking calipers 🔥

[@MatlasDI]

Yee boi

[@xtremewlr]

Nice job, I dig that color combo. Pro tip - Use 2 M6 (I think, 12mm head), short bolts to pop rotors off the hubs. That's why they have the threaded holes in them. Much easier than beating them with a hammer.

[@MatlasDI]

Yeah always a good option. Just had issues in the past with rusted rotors just destroying the threads so I turn on hammer time and go to town now. 🤣

[@Chase_AM]

I did the conversion rear parking brake shoes instead of the rotor, with the thinking that a rotor is a more regular wear item and I’d rather have a wide variety of rotor options rather than being tied to a single rotor.

[@MatlasDI]

Good way to look at it. Would be a step up if kns ever decides to discontinue the adapters. Honestly my brake shoes were barely worn at 230k miles. Maybe half a mm less than stock if that.

[@Chase_AM]

@@MatlasDI That’s barely anything! I guess that’s what happens when they’re engaging just to hold static and not being used for some drifty boiz

Nice upgrade! Brembo brakes = 🔥

[@MatlasDI]

Makes a huge difference for sure. Figured I'd try and make a somewhat detailed how to to help others out. 👌

[@Mike_44]

Super nice upgrade!

[@jayc5470]

Hey Matt, just wondering if installed the KNS oversized brake shoes on yours? I'm trying to find the correct rotors for mine to fit.

[@MatlasDI]

Got the kns/dba 4000 rears, so they just use the oem legacy/outback rear shoes. Fastwrx.com has everything you're after 🤙

[@gloglo1275]

Hey man. Question. I have a 2009 wrx. Doing this same brembo swap. I bought rotors from an sti. Would I have issues with the rear drum brakes or would it be a direct fit? Also I have stock 09 Wrx wheels and I guess I have to get spacers. Would 5mm be good enough? Thanks

[@Byrni1111]

Looks clean 👍

[@MatlasDI]

Thanks Byrni 👌

[@FADWC]

Woot! My allergies were fuckin murdering me all day, as soon as I started watching this it went away! Thank you! Haha great video!

[@MatlasDI]

Glad I could be of service 😆

[@FADWC]

@@MatlasDI the wheel gap looks like you gonna go rally bro haha the wheels are sick with those brembos back there!

[@MatlasDI]

Hahaha. Yeah that gap at first was wild. That was just from difference in spring compression rates. All fixed now, but worth a good laugh at first.

[@ymlas02]

So no issues with the stock MC moving all that extra fluid? The pedal doesn't go too low when applied? Just seems like a lot of fluid to move for those extra pistons.

[@MatlasDI]

No issues. The surface area is negligible between Stock 2 pot to brembo 4 pot. When bled it requires the same pedal travel and the abs module can operate normally.

[@carlost9824]

What did you need the spacers for? Were they required for the upgrade?

[@MatlasDI]

Not required for the swap. My wheels would contact my inner trailing arm in the rear due to size and offset, so I use a small spacer for clearance.

[@shiloh5199]

Great videos

[@MatlasDI]

Thanks 😊

[@alexanderenericavanwyk9909]

Sorry guys. Everyone is using all sorts of abbreviations. I have a 2010 outback. Will a 09 impreza STi be a direct bolt on? I will have to import brackets and things, which makes it impossible. I will have to get everything from a scrapyard, I need to know what models will be direct bolt on. Front, rear and master cylinder please.

[@lavishliamracing9329]

Will 2015 sti brembos work on my 08 LGT with the same stuff?

[@stephenwebb8424]

So where did you source these slotted rears because I was informed by FastWRX that DBA did not make a slotted conversion rotor?

[@spacegeek1534]

Looks great man!! What wheel and tire combo are you running?

[@MatlasDI]

Thanks man 🙏 Running 18x9.5 +45 wedsport tc105x with 255/35r18 continental extreme contact sports.

[@spacegeek1534]

Oh sick!! I’ve been looking for wheels and tires for my outback!

[@MatlasDI]

Have to use a spacer with these for rear clearance between the trailing arms, so if you're going 9.5, 40 would be the highest offset I'd recommend running. Hard finding proper offset wheels for these 🥲

[@spacegeek1534]

Ya it really is I was thinking like a 35 on a 18x9.5

[@MatlasDI]

Would be good. My old setup was 18x9+30 with 255/40s. Little bit more meat.

[@marka1837]

Nice work on the brembo upgrade! Is it pretty much 2004-2014 brembos that will work?

[@MatlasDI]

As far as the calipers, you can use any of this style sti, but gd is preferable, for the rotors you just need to make sure to get 5x100 style like that from an 04 sti. For the rear you can pick up kns/dba rotors that keep the rear ebrake shoe size, or swap them out for sti ebrake components and use normal rotors. Fastwrx has a huge selection so they make nice rotors like dba 4000's with that Internal drum 🤙

[@marka1837]

Great, thanks! Is there any real benefit changing the hub to 5x114 over 5x100? Can the 5x114 ever work on 05-09 outbacks? Off the topic Did you and Tanner serve in our military?

[@MatlasDI]

No one has figured out a rear hub solution for these cars yet to swap to 5x114. I want to give it a shot in the future and may try to on the outback this next time around, but there isn't an easily available solution. 5x114 hubs from an sti are a lot stronger, and you get much better wheel selection, so it would be a huge benefit if you could figure it out. I was never enlisted, but Tanner was in the army for a while 🤙

[@marka1837]

Thanks Matt. I had read that the 5x114 hubs are much stronger. I wonder if the whole rear sti suspension subframe would fit? I had thought about trying it awhile back. You have inspired me to get back into building beast aka the 06xt. It's been sitting for a couple of years with a blown motor. Going to slowly start piecing it together starting with the six speed swap and then build the motor to the power levels I've always wanted! You have built the best xt I've ever seen! So thanks for the inspiration! I'll thank Tanner for his military service! I thought I had heard you guys mention it at some point. Your great guys!!!

[@MatlasDI]

@Mark A i think our issue with a subframe swap is the trailing arm/ knuckle setup that these cars use, but i was considering machining out the knuckle to fit the sti bearing assembly. And thanks man, means a lot. 🙏 I can't wait to see what you wind up doing with it 🤙

[@lgt304]

What calipers were sourced for this swap any certain STI years ?

[@MatlasDI]

Any GD is fine. These were 04/05 sti

[@dominicmorones8314]

Does this conversion also work for an 07 gt limited? (Non-wagon)

[@MatlasDI]

Yes, all the 4th gen legacy/ outback.

[@vannevels6758]

I'll hopefully be doing this on my OBXT. 12K/10K?! I've got FA 500s with 8K/8K Hyperco springs and the ride is FIRM, a a 🤏 bouncy, and I don't think the sway bars are even necessary. I can't imagine how stiff your set up is.

[@MatlasDI]

The 12k/10k honestly felt money on my setup, it may have to do with dampening or preload to some extent on setup. Mess with dampening settings to get it to match with spring rates and you should be able to get any type of bouncing out.

[@dominicmorones8314]

Also what color did you use to paint the calipers? I really like that, think it would look nice with my satin white legacy 🤙

[@MatlasDI]

They are powdercoated an alien silver base with jamaican teal from prismatic powders

[@dominicmorones8314]

@@MatlasDI Thanks so much! Hope all is well for you and the build 😎

[@MatlasDI]

Np man thank you

[@RobHTech]

grinding it might reduce strength in that part sufficient to cause it to break under extreme force. Are the backs even really needed?

[@MatlasDI]

You could always do just the front, it may change bias slightly but more than likely would not be noticeable under standard driving. I don't believe grinding is necessary with anything but the aluminum rear trailing arms, and might not be necessary with a different adapter kit.

[@followtheornghat]

I died over the dog part 🤣😂🤣

[@MatlasDI]

He's my lil helper. Kind of. Lol

[@ChristopherFranz]

I'm a bit of a newbie to suspension etc. so forgive the stupid question... The blue piece on top of the brake assembly that connects to the body/inner wheel well obviously isnt stock, is that to help keep geometry correct when lowering the outbacks? I hear when lowering Outback you need legacy trailing arms I think it is to keep this all in the realms of "ok"

[@MatlasDI]

Hey man, not a stupid question. you've got the right idea, the blue arm is a megan adjustable upper control/ trailing arm. when you lower the outback the best way to keep geometry is to actually remove the spacers from the subframes and convert the components over to legacy spec which are designed for the engine/ transmission being at a different height. if you are only lowering the outback to around the height of a stock legacy it isn't a huge deal to do this, but if you're getting further into things, using adjustable rear trailing arms/ upper rear control arm is the best way to have the most control over where everything is located and get the alignment set up exactly how you want it.

[@ChristopherFranz]

@@MatlasDI awesome.Thanks for the info. I did see something about the sub frame spacers elsewhere but that made me nervous on my daily not knowing if I’d need new drive shafts from gearbox to diff etc. I was thinking of going legacy gt height. Where the arches are just in line with the tyre. Local laws dont allow anything lower than 100mm(4ish inches) off the ground :/

[@MatlasDI]

Should be okay then. the adjustable arms are pretty easy to add after the fact if you need to get more adjustment.

[@MaxBeecher]

I have a 2010 outback I want to do this with but from what I've read, it's a direct bolt on from the 2015 sti brembo's

[@MatlasDI]

I can't speak from experience on the 5th gen cars, but you'd still need to use the 5x100 rotors from '04 To match the hubs front and back as the sti is 5x114 and the outback for that gen is 5x100. E-brake may already be of correct size so may not need the kns rotor, but not positive. Would just need to check rear caliper clearance and bolt spacing from the knuckle. Fronts should bolt straight up like the other cars. 👌

[@MaxBeecher]

@@MatlasDI awesome thanks dude!

[@dillankennedy9607]

What year of sti are these off of? Or does it not really matter

[@MatlasDI]

The calipers need to be the GD versions so 04-07. Spacing is different IIRC on the 08+, at least for the rears. Best to get a set of GD golds to be sure.

[@dillankennedy9607]

@@MatlasDI thanks for the tip

[@nova12332]

sooo the rear rotors and pads were for the gd wrx? cuz some ppl say the rears are for lgt and itll fit the brembo

[@MatlasDI]

The rear rotors are a modified sti rotor offered by KNS and DBA. they feature the inner drum diameter for wrx and legacy/outback ebrake components. Pad utilizes standard sti brembo rear pads. You can either run the dba/kns rotor variants or swap ebrake components to sti and run a standard sti rear rotor.

Can u fit the factory wheels? The 17? Since I use them for winter tires

[@MatlasDI]

I believe so, but I'm not entirely sure. Might have to use some spacers, they should clear circumference wise, just would depend on spoke clearance.

[@dillankennedy9607]

@@MatlasDI thanks

[@Mr_BUSINESS_24_7]

What wheels are those ? How do we choose wheels sure to clear ?

[@MatlasDI]

My outback has wedsport tc105x's. The main clearance issue is the inner trailing arm on the rear. Determining proper fitment, I'd use willtheyfit.com plug in your current wheel size and then mess around with things to see where it gets you. I ran 18x9.5+45 on this car but ran into issues with it touching the trailing arm on the rear requiring spacers. Having tested a lot of sizes I think 18x9+38 is nice on this chassis; fills out the wheel well, close to the fender and the trailing arm, good scrub radius, and can fit up to a 255 without issue, but in the end it really depends on what look you're going for. There are a lot of threads on the legacygt forums for different wheel sizes and fitment. It's also worth noting that the front tracks wider on this chassis, so it isn't uncommon to have a spacer in the rear to make it look more uniform.

[@Mr_BUSINESS_24_7]

@@MatlasDI I thought the issue was ensuring the wheel spokes didn't interfere with the caliper. Thank you for all this great information. Real nice job on the powder and this video !!

Yeah no issues with the trailing arm sections. Only needs to be done on spec b aluminum arms iirc. Best to only take off as much as needed.

From what I've seen this should be the same or very similar for the prior gen legacy and outbacks as well. You would use the kns v1 rear caliper adapter like i did, front will bolt right up. 👌
