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

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.

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.

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.
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.

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 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?

(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.)

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.
