'07 Sti Brakes, experience with this swap?
 

Found a guy on Facebook parting out his entire 2007 STI. He has brembo rotors and calipers for $900. From what I understand this is one of the harder swaps to do onto the BRZ (year 07 brakes I mean). Any experience with this? Worth trying to do the swap?

The calipers will need the bleed valves moved to the other side. The rotors won't fit because they're drilled for 5x114.5, not 5x100. You'll need rotors from a 2004 STi or dual-drilled rotors like DBA.

It's an easy swap, not difficult at all

Fronts bolt directly on but you need new rotors that are 5 x 100. Nothing else is needed for the front.

Rears are a little bit more complicated. You need to buy an adapter. KNS Brake's Version II adapter is what you need. Also, you will need to trim or remove the dust shield because it interferes with the larger rotor. Again, the proper rotor is needed for the 5x100 and the P brake. The 2004 STi rotors will work Frt and Rr. Other options of redrilling 08+ (thanks streetthrowback for this correction) also. This is for P brake figment.

Read this entire thread and you will get information about the bleeder valve and plug swap.

Existing FRS break lines will fit but you need to use the STi Brembo banjo bold IIRC.

You will need to get new hardware to mount them too since the OEM FRS ones don't fit.

Make sure your rims clear. OEM ones will not work.
Good luck.

Correction the rear needs 08+ rotors, the fronts you can use the 07 rotors, I had the 07 rotors on the rear and they weren't seating properly, 08+ do

Thanks everyone for your advice, im still deciding if i want to do it. I currently have no space to do the swap so its a bummer. Guy is in ATX too, so kind of out of my way and I need to do more research!

Not worth it IMO, unless you really want it for the look.

Not worth it as brake bias could become an issue.

I have STI Performance brake pads for the stock BRZ calipers with stock BRZ discs and ATE Typ 200 brake fluid. I find the braking already too good for occasional spirited street driving.

I would recommend doing some more reading. There is a DYI thread on what it all takes and king Tut has a thread about questions/discussion. As stated above the full swap makes the car a lot more front bias. I would only recommend doing the front brakes, our rear brake is more than capable.

If you have not tried pads, stainless steel lines and new fluid I would start there. I have the STI front brembos and it is a upgrade. However in most cases the pad, lines and fluid is a good upgrade. This will also give you time to research if you want another BBK or do Brembos. There are plenty of Brembos for sale on NASIOC and no shortage.

Hope this helps some.

For that matter, our front brakes are more than capable at everything except heat dispersion. New pads and fluid and you're good for everything except heavy track days. And you can mitigate heat by installing cooling ducts.

The Brembos do look tremendously better though.

I'm not sure what's all the negativity surrounding the swap, I drive very aggressively, I bet the hell out of the car everyday and autox the car, and the brakes feel great, I'm not in it for the looks, I'm in it for the performance

There is zero performance benefit to this swap. Short of guys running wide slicks, we have plenty of braking power with the stock system. What we lack, for track use, is thermal capacity, but the STI swap doesn't help that at all.

Good pads/fluid will be all the vast majority of those autoxing or street driving their car need. You can even lap quite quickly on just upgraded pads/fluid without issue.

I have to disagree with you, I noticed the lack of brakes once I took it out of the box, the sock brakes on my lotus makes the stock brz feel very bad, not to mentions the Lotus has a swap motor in it and it still equipped stock Brakes

Ok, but why go through an entire STi brembo swap with no mention of what pad compounds you are going to use? Especially when better pads and real fluid perform for many people on the stock rotors and calipers?

You should also point out that many track rats are only using a front BBK!!!!

Look at @ImperiousRex and his insanely capable BRZ. Front AP Racing Sprint Kit with OEM rears, all 4 corners on good pads

this is the beauty of life, everyone enjoys different setup, I just talk with experience on the things I been through

better breaking doesn't shed time off around the track?

Did you try better pads first? What pads are you running on the STI brembos? I'm willing to bet every bit of difference you're feeling is because you're running different pads, and you could've done that way easier on the stock calipers/rotors.

If you're able to engage ABS, your brakes are strong enough already. On stock pads with cold tires (dunlop ZII's) I could still engage ABS, once the tires were up to temp I couldn't. I added new pads and fluid and I could easily engage ABS again.

See above... plus, tires are generally the limiting factor in how fast you can stop, not the calipers.

The OEM brakes can already engage the ABS. Since you can only brake as well as the tires can hold onto the ground, there's no real benefit to a brake system that can engage the ABS sooner.

People who go with the Sprint kit, which is designed to work with the OEM rear brakes to maintain brake bias, do so because it has better thermal capacity and heat management, and for a track-driven car replacement parts are cheaper over time. The STI Brembos, which were not designed with the BRZ rear brakes in mind, push the bias forward. This overworks the front brakes and causes them to overheat faster, which then overworks the rear brakes because the front brakes are no longer effective. The rear Brembos actually have less braking power than our OEM rear brakes do, so doing a full swap just exacerbates that effect. 95% of users will never notice, because they aren't putting that kind of strain on their brakes. The 5% that do will notice very quickly.

I would do the Brembo swap because it looks cool. If I wanted straight up performance, I would buy a kit that was designed for this car. Probably the AP Sprint or Endurance kit, since I don't live anywhere that sees snow or road salt.

Echo what everyone has said. Better pads,steel lines, and fluid is all you need. I am getting ready to try some new pads and new front rotors(Stoptech slotted) as recommend by the manufacture. On stock power, no need for BBK.

not worth it.

You will die in a fire, as seen here: http://www.ft86club.com/forums/showthread.php?t=86917

Most owners that did this swap are dead. I barely survived. Install at your own risk.

They died in a fireball explosion. While drinking fireball.

don't do it. everyone that read somewhere and never actually personally experienced it said its sucks and does nothing but ruin your car.

also, you'll end up locking up and dying in huge ball of fire as stated above by the prior poor restless souls. hell i'm lucky to be a live right now.

I don't think it's unsafe or will kill you, but it it's not going to improve braking performance compared to better pads. If you're doing it for looks, sure, but if you're after better braking performance there are much cheaper options that work better.
