Default The STi Brembo Brake FAQ - including "will STi Brembos fit on [x]?"

Not gonna try to get it all in one shot

General STi Brembo information

What replacement rotor options do I have?

-dealer prices
-cheap options
-blingin' 2-piece options

Update! It looks like NAPA now sells cheap blanks. Woohoo! Ken @ WRXBrakes sells em.

Brembo swap information

The Brake Interchangeability FAQ is also a great resource!
http://forums.nasioc.com/forums/show....php?t=1529797

What do I need to swap Brembos onto a WRX?

You can either
a) Swap 04 Brembos over - easiest if you can find them
b) Swap 05 Brembos over - a lot more work, though there are advantages to using the larger hubs and whatnot

Very cliffnotes version:

Rears, not so much, and you have to use a brake caliper adapter. I believe Ken@WRXBrakes has one, Dan@MachV has one, and Tom@Kartboy has one.

However, you can swap to a 06-07 WRX rear Caliper (same as JDM 2 pot) and run a stock 06-07 WRX or 04-07 Legacy GT rotor with the special l bracket Kartboy makes for the swap.

The two main differences between STi and WRX hubs is the diameter of the e-brake assy and the mounting points on the hub for the caliper.

Wish this thread was here when we did the 06 wrx with brembos!

This will help lots of people. WRXBrakes (Ken) knows tons of info on the swap!

I just recently installed a full set of Brembos on my car.

I will try to write an install thread, especially for the rear including brackets, when I have free time.

...just a few thoughts...
It would be nice to have:
- Info/part numbers for the rebuild kits, hardware (pins, clips, mounting bolts), etc.
- Torque specs for the bleeder screws & mounting bolts
- Bleed sequence (inner or outer bleed screw first?)
- Maybe a link to the "wheels that fit the STi" thread for wheel choices.

using TCE's brake bias calculator you can see the effect of running Brembos w/ different combos in the rear-might be worth running the numbers ie Brembo front/ oe 266mm rear, Brembo front/FHI two pot rear, Brembo front/Brembo rear etc

Legacy777 has a spreadsheet that calculates that stuff and has the piston sizes and effective diameters already in it.

http://www.main.experiencetherave.co.../brakemath.xls

Also, could we have a summary of what it takes to swap brembos? Something like this:

Quote:
Originally Posted by me
Brembos, like most other Subaru brakes, are interchangeable between models. However there are a few extra things that are needed.

Rotors:

The 05-08 STi has 5x114.3 rotors, where all other Subarus are 5x100. This means only 04 STi rotors will fit on other cars.

Rear Backing Plate:

The rear Brembos are 2-pot fixed calipers, and they will not bolt up to cars with 1-pot rear calipers. They will bolt up to an 06-07 WRX. To install them on another Subaru you need to swap backing plates (a pretty involved process requiring a press), or buy some adapter brackets. Kartboy manufactures adapter brackets and they are sold through various nasioc vendors.

Rear Parking Brake:

The STi has a 190mm parking brake. Most other Subarus have a 170mm parking brake. That means if you put 04 STi rear rotors on your car the parking brake will not work. Previously the options were to deal with it, have some spacers made to fit in the rotor, or buy expensive taller brake shoes from Godspeed in the UK. Fortunately DBA has started making a 5x100 Brembo rotor with a 170mm parking brake drum.

So, to swap brembos you need:

-Calipers and bolts (any 04-07 will work)
-04 front rotors
-kartboy rear adapter brackets
-DBA 2657 rear rotors

The 08 rear end is different and I don't think the calipers are interchangeable. You could use the 08 black front calipers though.

Yes, excellent suggestion. Sorry, just laziness on my part, and I am also hesitant to write something about doing a swap that I have never done. Yours sounds good tho

Just to add to the list. If your doing the Brembo front swap and use 07 sti Hubs, Rotors and Brembors on an 06 wrx you will need front struts and 05+ STI rims with the larger 5x114 also. I just did the swap and had to get STI struts for the front swap. This was all part of my swapping an 07 STI tranny into an 06 WRX. Still working on the wiring issue.

just in case anyone comes in to find the obvious.. but do the limited black brembos pretty much follow the same guidelines as the gold brembos? same brakes right? would just need 04 sti front rotors like that other guy said to put it on any wrx. sorry been searching for that forever and i think it would be easier if someone comes in here and sees that.

Just be careful with the 08 rear sti calipers. Someone reported on IWSTI that they do not fit the rear even with older sti hubs. I have not been able to verify this yet however.

So the rotors just change on the brembos in 05 5x114 and up. The 04 rotors are 5x100. But does the calipers change how the bolt up ?

I too want to know about this. I've heard the only difference is length but I'd hate to be realizing they won't bolt up when I'm too far into the project!

If you look the Goodridge lines are the same for the WRX and STi. I have 04 STi Brembos on my 03 WRX.

Just so you KNOW they will work, I specifically installed the part # 24215 I still had the package, the funny thing is it's in the trash can on the curb. Trash pickup is in 10 hours or so.

A little bird told me that Brembo pretty much says that your caliper should NEVER need to come apart... and thus, they don't sell a rebuild kit of any kind for them. I was looking so I could un-ass them for coating... no such luck, and I'm not about to take them apart with the hopes that I can just use some beefy o-rings to put it back together.

Another note... I was just reading the last link in the op, and it says TWICE in that thread that the torque spec for the Brembos is 114.3 lb/ft and "over 100".

I'm pretty sure that's bull****. The 2 manuals I checked showed 59 lb/ft... damn near half of what they are suggesting. I wonder why they had stripped threads?

they sell caliper rebuild kits for both the front and rear Brembos- available from your dealer or anyone that deals in Subaru parts

the caliper doesn't come apart, but the pistons are removed to replace the boots/seals- if you run track days a fair chance you'll at some point need to rebuild them
