Those pieces look pretty complete. The only thing out of OE spec I went with was the Stoptech stainless lines.

was it a simple swap? what did you need to do to accomplish it

Yep. Everything bolts right up. I ordered all new parts that included:
calipers
pads
rotors
stainless lines
shims/pins/springs/spacers
banjo bolts

It's about as simple a swap as you can do. It's not really a "big" upgrade. It's more of a lateral move. The "real" upgrade was the pads, rotors and lines

How's the brake bias/feel? These might be a cheap upgrade, since STI calipers are $$$$

in the picture do you think everything is there? The price they are asking is 600..is that a good price? @Beyer Subaru

Feels great. Some have mentioned that it will move the bias to the rear. But I can't really notice that in my butt dyno. I haven't really beaten on them yet as I want a good bed in. But the times I've needed them they worked great.

Yep, there is more there than you need. You won't use the spindels or the control arms. The life of the pads/rotors is your only real concern. 600 is a great price if there is life left on the pads/rotors.

If the pads and rotors are beat, then you are just doing a little better than buying the calipers new. They run about 600 for both calipers new.

I've been looking at these. Are the calipers cast iron or aluminium?

I have these 4 pots on my wrx and the feel is pretty similar to the stock BRZ brakes. The wrx has crappy stock brakes so it's a big upgrade, but the BRZ brakes already have decent feel. I think the only real benefit you'll get from these is increased thermal capacity, and the bling factor. Just new pads and rotors will be fine for most people, and the other people probably should step up to a big brake kit. These 4 pots are very popular on rally cars because you can fit 15" wheels around them.

Not sure if this applies to the brz, but on the wrx another common upgrade is to install a legacy caliper bracket and legacy rotors, which are 1" bigger diameter but use the same calipers (same swept area). These shift the bias to the rear even more and together with the 4 pot brakes and SS lines it's an awesome and cheap setup on the wrx. Might be able to do something similar for the BRZ if the parts fit.

Cast iron. They are pretty heavy. I haven't had my BRZ brakes off yet but I would guess they are heavier.

:word: Pretty much spot on words of advice. I don't need a BBK for everyday use and the extra costs nor do I want the Brembos.

This was a cheap and simple upgrade for me that was about half the cost of any comparable BBK and gave me some OEM bling.

I don't really recommend hunting down brakes from GC's as they are approaching twenty years old now and might need to be rebuilt. But if you want a cheap, simple, bling bolt-on kit these are them.

The BRZ/FRS front brakes are the SAME as the 09-13 WRX (and a host of other Subaru Forester and Legacy models) - and the rears are from the 2010 LGT.

The 4 pot front caliper was also used on 06-07 WRX's. It uses the same 294 x 24 rotor that the BRZ etc use. It's an extremely durable caliper that is still used by rally cars. Good race pad selection, cheap rotors, etc.

(One note - the basic 294 x 24mm rotor was changed in 2005-2008 depending on car model. They added vanes/mass to increase the heat sink abilities. That is the rotor your car comes with.)

The front 4-pots are cast iron.

The rear 2 pots are Aluminum.

You are referring to the 'H6' upgrade. Your car already has 290mm rear rotors and in fact they are vented so H6 need not apply.

DANGIT!! i knew i should have saved my 22B Front 4 pots.

Nope. I didn't refer to the H6 upgrade. That was spacewilly. Thanks though for the informative posts.

And those cars all weigh 500+ lbs more than the BRZ, so doing the 4 pot conversion on those is worth it. WRX brakes are just fine for this car, they are not fine for a WRX. My WRX brakes used to be cooked at the end of a 40 second rallyx run. So far I've yet to experience heat fade on the BRZ during autox, but I haven't taken it to a track yet. When I do I'll get higher temp pads and fluid and I'm 99% sure those will do fine.

That's true, they are perfect for rally cars, since they are the biggest brakes you can fit 15" wheels around, and it's very easy to find spares. If you are building a rally car, go ahead and do the 4 pot upgrade. Otherwise, in my opinion it's not worthwhile.

Yeah I didn't bother checking which brakes we had in the rear. Thanks to others for finding the info. Just more proof that the brakes we have are more than enough for this car.

My bad - quoted the wrong post.

:word:

Yep, these brakes are more than adequate for our cars. I just wanted a bit of an upgrade and threw in some bling. I kinda got the inspiration from the Xt Line Concept - http://www.ft86club.com/forums/showthread.php?t=18475 I just wasn't really feeling the Red at all and went with the Black instead.

The 4 pot calipers will save about 2 pounds per side. 12 pounds for the 2 piston caliper/bracket - 10 pounds for the FHI 4 piston caliper. (Weighed on crappy shipping scale)

Fixed calipers offer better pedal feel and more even pad wear than floating calipers.

If you ran the old style front rotors - WRX up to 2008 - you can save another 2-3 pounds per wheel.

And a mountain of brake pad compounds to choose from.

The front D929/1539 shape is not bad for pad choices - but the 1124 rear is pretty limited. The rear however would require a bracket to run the 2 pot FHI though. It's AL though and would also save a few pounds per corner.

Yeah it definitely looks better. Once you start upgrading tires and power it probably will become necessary to upgrade the brakes, and this could be a good way to go but I'm not convinced it is much of an improvement over the sliding calipers besides the looks.

Also rear pot will fit plug and play ?

I think you would need this

http://www.knsbrakes.com/images/Bracketv2/IMG_1480.jpg

I have the red 4/2 pots on my Impreza coupe.

$600 isn't that great for used ones. I recently sold my old set of black 4pots for $300.

You can get brand new 4pots with endless slotted rotors and Hawk HPS pads for about $850.

Check out Subaruwrxparts.com they're one of my local dealers and I get all of my parts through them.

You will more than likely need the Kartboy adapters for the rear 2pots. The 2pots are around $1k new for everything since the Kartboy adapters are super overpriced.

It's a different bracket for the newer cars.

I was under the impression from reading up on the Brembo 2 pots, that our rears actually outperform those, and these? I understand the concept of reducing the unsprung, but TBH, I'd be more concerned about the bling of matching all 4 wheels than the weight that I likely won't notice around town. So from what I understand, keeping the LGT rear sliders with Brembo fronts shifts the bias of the normal Brembo setup to the rear a little, and the same with these, if not more than the Brembos? Also, these will obviously fit in a smaller barrel, what about width? Think these will fit behind the ridiculously high offset stock wheels? I imagine that they might hit the spokes- and adding spacers AND rotors, pads, rebuilding etc I just feel like would put me in Wilwood territory... And I love Wilwoods. I want my Miata and my FRS to someday have lots of wood if you catch my drift haha. Actually- dream kit for the FRS is KSport 6 piston "whytheeffnot" setup.
@KNS_brakes Also, I'm a bit confused- Our front rotors are the same as the 294/24 or whatever WRX correct, which Is the same one that uses 4/2 pots? So why no use ZN6 rotors with these? or is offset from hub different or something?

Is this just the calipers or is that the rotors as well? Im wondering because a local guy has 06 wrx frozen rotors front and rear brand new for a cheap price.

The older 294 x 24 Subaru rotors are the same outside but have fewer cooling vanes and are lighter overall.

So they will work just less cooling vanes?

Yup -=and they are lighter

nice. I know in the thread here a couple people have said it is more of a linear move going from the brz brakes to the 4pot 2 pot setup. Anyone else tried this out and feel differently?

Reason I ask is im weighing the options if this is the route I should go or just get a set of frozen rotors a set of hawk hps pads and call it a day.

Rotors, pads, SS lines. All you need really

Tips and tricks
 

I am super excited to try this out as soon as it warms up. Anyone have any install tips and tricks? Does the front dust shield need to be modified at all?

No tips or tricks for the fronts. They will bolt right up and you won't need to trim or change anything. The only thing I found that I needed was the various shims and spacers for the new calipers/pads.

Hey bro I got the same set up, but now my brake pads are done... Do you have the part number for the brake pads? Thanks a mill...

Here is my set up... Just placed TRD Stickers (removed the Subaru off)

Thank bro :cheers: :burnrubber: :thanks:

You'll have to go to an online catalog and look up front brake pads from a 06-07 Subaru WRX.

I got help thanks to @Beyer Subaru (Matt Nemetz) :thanks: :respekt:

Is there any issue with the fact that you swapping sides on the front calipers to fit them to the BRZ?

The FHI 4 pots are not differentially bored, so no - no issues.

Does it put the bleeder valve in the wrong place?
