Everything we know about PP Brembos
Given how much positive feedback I got on the topic about wheel fitment for PP Brembos,
and how many things most people still don't know about them, I decided to start a new topic about the brakes themselves. OEM Subaru part numbers
Torque specs Front caliper bolts: 88.5 ft·lb or 120 Nm (19 mm socket) Rear caliper bolts: 53.8 ft·lb or 73 Nm (17 mm socket) Bleeder valves: 14.8 ft·lb or 20 N·m (11 mm) The rotors have two M8x1.25 holes each for bolts to simplify removal. Piston sizes 4x40 mm front [citation needed] 2x40 mm rear [citation needed] Compatible rotors Fronts are 326x30mm, rears are 316x20mm
Compatible kits
Please post any other useful information you might know about these! |

They use the standard OEM Brake pad sizing for Subaru, which is common to other OE Brembo systems (Can be referenced in the Brembo attachments). This typically also applies to the 4pot/2pot Brembo GT system
See attachments Project Mu shape code:
WVA code:
Attached Brembo pdfs also show information about approximate pad width, height, thickness, though I'm sure there is some allowable play in the exact dimensions among parts makers

Can we confirm which years of WRX STI Brembo pads will fit with the BRZ/86 Brembo's? Currently I'd pretty confident the 08+ STI size pads are cross compatible.

Another 2-piece rotor alternative are Girodisc rotors. More info in this thread: https://www.ft86club.com/forums/showthread.php?t=140428
Front fitment (A1-007) is confirmed to fit, but rear is still up in the air. |
Also, the FMSI D Number (defines the pad shape, etc.) are listed below:
Front Pads: D1001 Rear Pads: D961 These shapes are common between WRX STi (04-17) and the PP Brembos. I believe the front pad shape is used for a lot of different cars with OEM Brembo brake setups, including WRX STi (04-17), Lancer Evo, Civic Type R, and others. The rears are common with WRX STi (04-17) again obviously, Lancer Evo, G35/350Z with Brembo options, and others. Just something to keep in mind while you're shopping for pads. |

Also the PDFs don't do a good job of recapturing the additional compatibility info in the tabs from Brembo parts site For others, feel free to browse: 86 https://www.bremboparts.com/asiapaci...ey/000121184-1 BRZ https://www.bremboparts.com/asiapaci...-0/000124014-1 WRX STI https://www.bremboparts.com/asiapaci...wd/000100922-1 |
I used the PowerStop Z23 carbon fiber pads on my last car, and they were excellent for a street pad. Virtually no noise or brake dust, but with decent initial bite and fade resistance for "spirited" canyon runs. After experiencing the massive amounts of brake dust from the stock pads, I'll be swapping them out ASAP. ;)
The PowerStop Z23 front part number is Z23-1001 and rear part number is Z23-961. There are also the Z26 carbon fiber / ceramic pads, which are supposed to be a further step up in performance. Part numbers for those are Z26-1001 and Z26-961. They also make some "stock replacement" pads (Z16 and Z17) and some "Track Day" pads, and some drilled and slotted rotors. They also sell some pads and rotors together in kits. You can search what's available at www.powerstop.com, and they link to several online vendors. There are also lots of other pads available to fit the OEM Brembo's listed on www.rockauto.com. |
StopTech Sport 309.10010 front pads and 309.09610 rear pads work well. Used them for one season of autocross and two track days and I'm very happy with them.
