I've done some searching on this site, the other site, and the general interwebz. I cannot find any performance brake pads for the front and rear for my 2017 crosstrek. I've used EBC red stuff on all my street cars with fantastic results. I would like to use these again. One of the weaknesses I've found in the streak is the lack of braking confidence, this is only perceived by myself due to having always driven light weight vehicles for autocross. (I kid you not, this trek is at least 800lbs heavier than anything I've ever owned.) so due to the mountain roads I have to contend with periodically, I fear brake fade. Especially since I have a CVT. Various websites don't list anything. They do list for the 2013-2015 model, but I don't know if those are the same.

They are the same. I am 99.99% sure the brake pads on all 2nd generation Subaru XV models are the same shape.

The FMSI brake pad numbers are as follows:

D1539 [FRONT]
D1114 [REAR]


How hard are you intending to drive? If you drive nearly as hard or harder than me, you should set a minimum benchmark of a brake pad compound that has a maximum operating temperature in excess of 1200 degrees Fahrenheit (648 degrees Celsius).

For reference, the friction rating of the OEM brake pads is FF, which has a coefficient of friction range between 0.35 to 0.45 both hot (600 degrees F) and cold (0 degrees F).


The front brake pad shape is shared with the following:

2014-2017+ Subaru Forester non-turbo (2.5i)
2010-2014 Subaru Legacy 4-cylinder non-turbo (2.5i)
2010-2014 Subaru Outback non-turbo (2.5i)
2008-2014 Subaru WRX

The rear brake pad shape is shared with the following:
2012-2016 Subaru Impreza
2014-2017+ Subaru Forester non-turbo (2.5i)

I may have missed some, but that should be most of it.

So wrx fronts, but not rears?
Basically. The fronts are shared with many vehicles, so commercial availability is high for the front brake pads.

The rears are limited to the Subaru non-turbo compacts and are much more difficult to find.


I'm going to go out on a limb and recommend the following brake pad compounds if you expect to encounter harsher-than-normal conditions but situations that aren't has hard as the ones I encounter:
  • Winmax W3
  • Project Mu B-force or B-spec
  • Endless SS-Y (Super Street Y-sports), SS-S (Super Street S-sports), or SS-M (Super Street M-sports)
  • Carbotech AX6
  • G-Loc R6
  • Hawk Performance HPS 5.0

All of these compounds would generally qualify as performance street or autocross brake pad compounds. Not quite race pads, but not quite regular street pads. As a result, they may be noisy and may fade if used under extreme conditions that I encounter such as continuous extended spirited downhill driving.

Standby for part numbers ninja edit, I am searching for the part numbers.




EDIT: part numbers found

  • Winmax: front WM-580-W3, rear WM-655-W3
  • Project Mu (PAD SHAPE NUMBERS ONLY, not compound specific): front F914, rear R914
  • Endless (PAD SHAPE NUMBERS ONLY, not compound specific): front EP386, rear EP418
  • Carbotech (PAD SHAPE NUMBERS ONLY, not compound specific): front CT1539, rear CT1114
  • G-Loc (PAD SHAPE NUMBERS ONLY, not compound specific): front GP1539, rear GP1114
  • Hawk Performance: front HB711B.661, rear HB557B.545

Ok, so it's the daily driver, so I also need the brakes to stop when cold. The wife is not a race car driver, so she doesn't understand the "get them hot" strategy.

I'm sure I'll catch crap for this, because I'm not recommending a specialty brand. But....I used Autozone brakes on my Mazda 3. Fronts were ceramic, and rear were metallic. You got three choices, I chose the most expensive, which were about $50.00. They lasted about 90k. They were also FREE lifetime warranty. I bought replacements, brought the old ones back, and got all my money back. I don't know how they can do it, but they functioned well and lasted as well. When I'm in need in the future, I'll be checking to see if there is an application. Now, someone or everyone tell me how I'm wrong please.

Actually, having worked at autobone, I can attest that their brand is made by someone else and repackaged. Last I heard it was duralast. That being said, I would never disgrace a Japanese car with sub-par American/Chinese products. It's genuine subie or track made products like EBC.

Based off of that, instead of a performance street, you wish for a mild performance street compound. Initial bite is the priority right? And I'm going to assume fade resistance isn't as high of a priority. How about brake dust?

For cold bite and operating temperature comments:
  • Winmax compounds W1, W2, and W3 have a listed operating temperature that start from ambient temperature. The W3 may be too aggressive in terms of maximum operating temperature that is 600 degrees C or 1112 degrees F.
  • Project Mu B-force and B-spec compounds I listed already have a listed operating temperature that start from about ambient temperature but may be too aggressive in terms of maximum operating temperature that is 500 degrees C or 932 degrees F.
  • Endless compounds SS-Y (Super Street Y-sports), SS-S (Super Street S-sports), and SS-M (Super Street M-sports) I listed already have a listed operating temperature that start from about ambient temperature. But the SS-M may be too aggressive in terms of maximum operating temperature that is 530 degrees C or 986 degrees F.
  • Carbotech offers only one pad compound with true cold bite, and that would be their mild performance compound 1521 with a listed operating temperature that starts from ambient temperature.
  • G-Loc offers only one pad compound with true cold bite, and that would be their mild performance compound GS-1 with a listed operating temperature that starts from ambient temperature.
  • Hawk Performance brake pads all seem to require warm-up, so I don't think I would recommend any of their compounds in regards to cold bite.

From a friction and initial bite standpoint:
  • Winmax compounds are on the mild side in terms of friction. The W1 has a coefficient of friction of 0.29 - 0.32 (actually lower than stock), W2 has a coefficient of friction of 0.32 - 0.35 (actually lower than stock), and the W3 has a coefficient of friction of 0.34 - 0.37 (on-par with stock).
  • Project Mu B-force and B-spec have a coefficient of friction of 0.32 - 0.45 (about on-par with stock with expected better friction at higher temperatures)
  • Endless compounds basically match stock friction with expected better friction at higher temperatures. SS-Y (Super Street Y-sports) matches stock at 0.35 - 0.45, SS-S (Super Street S-sports) has better bite at 0.38 - 0.45, and the SS-M (Super Street M-sports) surprisingly has lower friction at 0.30 - 0.40 despite the much higher maximum operating temperature.
  • Carbotech and G-Loc, despite not listing their coefficient of friction ratings, will likely have a much higher friction rating than stock based on my experience with American performance brake compounds. Hawk Performance also probably has compounds that exceed stock friction ratings.



Based on all of this data, I would recommend the following with an emphasis on higher friction and advertised cold-bite:
  • Endless SS-S (Super Street S-sports)
  • Carbotech 1521
  • G-Loc GS-1

No brembo, wilwood, etc. , actual brake upgrade. Don't know if you would need one for a car that people complain is under powered. What are you going to be doing with your car? What's the practical application for the performance brakes, on a car that's stock like mine?

Ok cool. Thanks man. Brake dust doesn't bother me at all. Fade is second priority.
Thankfully, all those three are low-dust pads anyways if that was going to be a problem.

Regarding trying to get the Endless pads, I highly recommend you give Endless USA a call or email to verify availability and/or locate/identify authorized local and online vendors, as there is the risk of counterfeit Endless products on the market. Their number is (714) 842-8551 and email at [email protected]

Carbotech and G-Loc are also small companies but don't carry the same weight as the well-known Endless brand (most famous for their common use in the 24 hours of Nurburgring race), but I have not heard of imitations of their products existing.

A full brake system upgrade is generally overkill for most except for those who truly push their vehicle to the limit (think glowing rotors kind of hard driving). All a larger upgraded brake system does is increase thermal capacity, cooling, and allowing for the use of milder compounds due to the improved cooling and thermal capacity but will not contribute to shorter stopping distances if appropriate brake pad compounds as well as matched tires are not also presently installed.

For an overwhelming majority of people, a brake pad upgrade will suffice considering the tires are the biggest limiting factor for the brake system. The stock brake system can lock up the tires, indicating it is more than powerful enough to suffice. Hell, most production-based stock-type racing series simply use stock brake calipers with racing brake pads.

The limiting factor of the stock brakes is usually the stock brake pads do not have sufficient high temperature capabilities, usually overheating around 500-600 degrees Fahrenheit, not even at the point of glowing rotors. Also, DOT 3 brake fluid won't bode well with very high brake temperatures.


With a mild performance brake pad, one is improving the immediate response (less effort required vs stock) as well as improving the repeated-use performance (less brake fade means longer amount of time pad is effective) which can really make a difference in serious driving situations (such as emergency panic-stop braking) or expressway use (repeated moderate-speed stops).

Appreciate your knowledge as usual AWD. I have no complaints about my breaking system. I also followed the proper break in procedures for the car, including the recommended procedure for the pads. Guess I will see how long the pads last. I'm not an extreme driver, and don't beat on my car. I'm not constantly getting on the brakes. When they wear out, I'll consider options. Judging from how long the last car went, and the relative light weight of ours, I'm not worried. I also don't have the automatic braking system on my car. I don't know what role that would play in brake wear either. If I had a heavy foot or was more reckless, I would go for the overkill and added expense of a system upgrade.

I actually know a few people who went and bought all new rotors/pads with the lifetime warranty for their wrx/sti.

They swap on the Autozone stuff for Autocross, beat the living **** out of them and return for a fresh set for the next event lol.

When you know enough, you can race ANYTHING. Even a cvt car. This car isn't underpowered. I don't know where people get this from. I've driven momentum cars my whole life. 148hp, 145tq, and 3200lbs SOUNDS slow, but the the CVT actually has less drivetrain power loss than a traditional automatic. You think this is slow? Try driving my old 2011 Honda Fit. 2500lbs, 117hp, 92tq. Five speed auto. S-L-O-W. but by today's standards my old crx was slow, my ae86 was slow (until I swapped it), my s13's were slow (until I swapped it), my point here is "slow" is relative to the perspective. The people that that complain were probably driving wrx or sti cars before this.

I feel that a lot of the people who think the crosstrek is slow, are probably similar to those who thought the BRZ/FRS were/are slow.

The XV is slow, but I assure you that it's more than capable with keeping up if you can hang with WRX's driven by lesser-skilled drivers in twisty stuff... not that I would know anything about that :eek:


And besides, I enjoy having a momentum car, as my dependency on power output is minimized.

I'm not personally saying it's slow. I love my ride. I'm very happy with it. I'm just echoing the criticisms I see almost daily from a lot of people. I have it as my daily driver, and can't risk beating on it. I'll be happy to get through winter ❄ without being white knuckled for a change. As far as the brands, I'll use whatever works and lasts best. I do appreciate the support and stories though. Keep them coming.

For most typical drivers, my local Subaru mechanic swears by Akebono brake pads. They're the same manufacturer that makes stock brake pads for a big chunk of the automotive industry, but their aftermarket brake pads are definitely a best buy. My local Subaru mechanic said he has never had a comeback from recommending those pads to his customers.

I also sold a set to a local XV Crosstrek driver and haven't heard any complaints from them either.


I also forgot, for additional brake system upgrades, one should consider getting stainless steel braided brake hose as well as a master cylinder brace. Both have a pretty substantial improvement in pedal feel, removing much of the mushy soft pedal feeling some may not quite like. The brake hose that I know of specifically for the XV Crosstrek can be had from Mann Engineering, while the master cylinder brace is the same exact one applicable to 2015 and newer model year WRX and WRX STI.

Im running around on every NFD i find ( national forest road ) @ all seasons.
Living in Oregon the PNW is my backyard,,not had issue yet with stock componets tho im due for new pads .. and looking for as stated a lesser “mushy,soft pedal feel” .. cant stand the softness when needing to suddenly brake an avert..reduces my confidance in breaking ability,lending to limiting my own ability to boldly go where no 30k$ car should go haaa.. (blue collar worker)
So before my adhd runs away with this question..let me wrap it up..

1.stainless steel braided brake hoses from Mann Engineering
2. Master cylinder brace ..??
3. Pads from — ?? crap forgot to make note of those before replying and cant goback an see without loosing what wrote sofar ..

2015 xv crosstrek limited with eyesight ( why they label it limited - dont make sence to me- i ordered with every option possible except hitch and rearview mirror compas thingy .. sportmesh grill wasnt able to add at time due to manufacturing changes at time :mad:

Tottaly greatful for recomending hose ! forgot all about that- I Seek protection as much important as performance .. no twigs-rocks-mud-ice-snow-sand need be a concern for slicing or pinching or ripping ect my hoses ..!!
