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

Beyer Subaru 02-20-2013 07:55 PM
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 $$$$

wholeeoh 02-20-2013 07:58 PM
in the picture do you think everything is there? The price they are asking is 600..is that a good price? @Beyer Subaru

Beyer Subaru 02-20-2013 07:58 PM
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.
