'07 Sti Brakes, experience with this swap?

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.

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.
