Neat video! Looking forward to seeing more videos and hopefully some on road/track talk, as well. Re: j-hook design, I think I remember reading that gases released from the brake pads are better dissipated, increasing friction, when clampin' down : )
2-piece rotors for lighter weight, but also less thermal transfer to hub. I ran a Stoptech BBK for a while, superb quality. Much better pedal modulation, absolutely zero fade on-track.
Lots of theoretical gains but how about some simple numbers? What is the braking distance with OEM vs this kit? That ought to be the biggest metric which people use to decide whether or not to buy this.
TheLeesto AP racing big brake kits aren't so much about pure breaking power and more about stability. Contrary to what most people think, 2 piece rotors are not meant to save weight. They do but it's no their primary purpose. They were first invented to manage heat: 1 piece rotors in race conditions would break because they would get so hot and would expand so much that they would crack and shatter but 2 piece rotors have oval shaped mounting holes (between the two pieces) wich means they can thermally expand without cracking. This is espescially true with the big one piece rotors you can see on road cars nowadays. The 4 pistons will help with pedal feel and brake control but the pad area is the biggest determining factor in braking power. What I mean to say is that you could probably get the same braking power from a simple pad change on the stock pieces but the difference comes when you go to the track. That's why everybody will tell you you don't need a bbk if you don't abuse your car.
this is for early cg8 and forester gt up to 2002 = every body knows subaru had 4 piston brakes from 2002 onwards with subaru on the caliper moving onto brembo 4 piston a little later = so only really good for race or rally - go to the wrecker - it will be cheaper and get new discs not much cash. i did and fitted high pressure brake lines !
Dear uploader, do you guys ship to malaysia? Secondly, this particar brakes with 4pistons are just for the front, so the rear stays stock? Can the rear be the same discs as well with 4 pistons? Thanks
Hey man, as far as the dust /heat shield goes its your choice, but the j hooks and the vents need to be facing the forward rotation. What you have done is the reverse, where the vents are not scooping up the air and the j hooks are not opposing the pads. You should consider changing this immediately
+Dj Hazard all rotors with angled fins, are to push the heat from the inner area of the rotor to the outter, not the opposite. why would you push the hot air towards the center of the rotor?
0:27 Actually I think most F1 teams use Brembo or Akebono (McLaren)... But certainly AP Racing are widely used in other racing classes :) And F1 brakes are tiny (since 13" wheels!) but very stout indeed! :D
I'm looking to buy new wheels very soon. I want to make sure the wheels I buy allow for a brake upgrade later on my 2015 wrx. How do I make sure I don't buy the wrong wheel?
is this safe and long last for daily all season? I live in New Hampshire and wonder the reliability without the dust shield, can it fit with dust shield still on ?
I'm interested, but how will this effect the torque vectoring and vdc?? Is it a drastic difference while turning? Don't want the car to over compensate or anything. On a curve the car's giving me a lot more credit then I should have with stock brakes
if your not a hardcore track enthusiast but still want to take your car out on the track without much brake fade whats a good set of brake pads that arnt to pricey?
Stoptech street performance or sport. They are same pad, just used to be called the former and then switched to the latter. (Or viceversa). Have them in my m5 and they work well under light track use/racing. You need better fluid and I’d install stainless steel brake lines.
The pads we use are for track use. When hot they make no noise. If your car is more of a daily driver then there are pads we can supply in this kit that will be silent during daily driving and also provide decent track performance.
so would you say it would be a good idea to get these for daily driving? they should last a really long time with the thicker pads and the fact that it wouldn't be pushed hard as if we were on the track. Just a question so save the sarcasm or dickhead comments please.
That awkward moment when you shit on Brembo to praise Brembo... AP Racing is owned by Brembo. But, even if it wasn't, discounting Brembo's place in the automotive world is stupid. There's a reason they're used in almost every single HiPo production car out there. And it's not because manufacturers think they're incompetent.
Couple things with this video: #1 not saying its going to make a difference but on the OEM weight of caliper, you left the brake line attached where you didn't measure the line with the BBK. Still going to be lighter i know but still mis-representation. #2, "J-Hooks" are just for looks and "Pad scrubbing" Their job is not to dissipate heat at all.. Mainly their for scrubbing the brake pads and for looks! #3 when you're looking at the vane geometry, its not necessarily more "air flow" that the geometry accomplishes. Compared to the OEM straight vanes, the curved vane geometry acts like a pump per say to "pump" the heat out and create a more laminar flow.
@@johnvelazquez9579 marketing BS, they don’t allow any gaseous out flow due to their design, so I’d agree with the poster above they are more about looks than about function. Now if they extended full width of the rotor & allow for gaseous outflow they could help with some heat dissipation, however they don’t.
I would like to get the Radical 6 piston brakes for the front, and 4 piston for the rear for my 2017 wrx. Do they make kits for this? I have larger wheels than oem
They do.....Wilwood brakes from TCE performance. 6 piston forged billet front calipers and 4 piston forged billet rear calipers. 2 piece rosters front and rear.
Donell Clemons in my experience with my old STi's the only need for an upgrade is for track use. the Brembos will fade faster. if your only street.. meh
It is better to use standard TQ values than just 'good and tight'... Good and tight is subjective and unsafe BC one person will over tighten, and the next under. Take five min online and find standard TQ values for thread and diameter size :) And of course, if in doubt, Lock Tight!
There is a link in the description to our website -> www.subispeed.com/2015-subaru-wrx/brakes/big-brake-kits/ap-racing-competition-brake-system-sprint-2015-wrx.html#.U5r_ePldV8E This will also fit the 2013 STI so good to go if you want to order a kit. :)
Yeah honestly you don't need all this unless your on the track. Stoptech makes a full kit that has better pads, rotors, and stainless steel lines. I also recommend a master cylinder brace.
darn I hate you guys lol now I want to get a wrx or sti lol. Had the 03 wrx and loved t had a 08 evo x and it was fast and fun took to mods well. have a 13 accord sport stick as a dd now and wanted a new vette the only thing is I don't track anymore mainly due to working all the time. I think a sti might be a great toy for half the price. yeah its not as fast as a vette but tune the darn thing get some ohlins and u can rip up any road. The only thing is is want a 2.5 fa with hydrolic steering in a sti.
Brembo who? :D Really bro? REALLY? Seriously, AP Racing make very competitive products, but you can't just underrate Brembo's work in the industry for 50+ years like that. Also, as far as I know AP Racing is a part of Brembo Group brands, but I guess that's another topic..
gt3076rCA Yes, I was put off by the "Brembo who" comment in the video. And yes, Brembo bought AP racing in 2000. en.wikipedia.org/wiki/Brembo#Brembo_Group_brands Brembo has been producing brake components forever, since the 60s.
MrThePrivateer those track tests done by whoever it was, dont prove jack shit. That depends on the tires, driver, and what the conditions were duing testing. Depending on that, it can change. I hate how you people just look at track tests and instantly state that one car is better than the other. I own a 2009 nissan gtr, and personally hate it when people are like "oh dude the gtr can do 0-60 in 2.7 seconds which means its faster than the aventador that hits 0-60 in 2.9 seconds. Like get that bullshit out of here. you cant judge a car based on their 0-60 times. The aventador will fucking smash the gtr above 60mph
When someone goes keeps commenting on TH-cam about how many cars they own, 99.99999% of the time they are full of shit and just trying to impress someone. I know you probably live in a dumpy trailer park and try to act cool online, but you should just really stop while you're ahead.
for a street car and some auto crosses, the oem floating/sliding caliper is adequate. Just get some dot 4 brake fluid and a good set of upgraded brake pad and you will be ok. But for track duty, I agree with the SubiSpeed gentleman. Alcon BBK is also a good choice but I do not know if they make them for the WRX. The Brembo BBK that come with the STI is an INFERIOR product. The Morons that have been design this set up for the past decade for STI should know better. This is because the aluminum Brembo caliper is mounted directly into the knuckle assembly to hold the rotor. The problem comes in when it is time to change the rotor, thus you have to remove the caliper to get the rotor out. The heat, rust and foreign matters the have been accumulated over the years caused the stripping/rounding off the threads on the Brembo aluminum caliper or making the job a lot difficult. Even if the mechanic used hand tool to remove the caliper bolts that attached to the knuckle assembly. You have to be stupid to use impact wrench on this. Once you damaged the thread on that Brembo caliper, the best option is replacement. You can try to re-thread the caliper and the knuckle assembly but it is not safe. As a result you will turn it into a bigger job and more headaches. And the aforementioned MORONS from Brembo did not make the caliper braket like AP RACING, Alcon, J's Racing and Spoon Sports calipers.
**WARNING** Follow the Subaru factory service manual for proper installation. This video is not a proper installation of the big brake kit. It skipped one very crucial procedure. Even with relatively low mileage on the bearing hubs and brand new high quality brake rotors, you should still measure for lateral run out for the rotors and index the rotors in such a way to minimize run out. I have seen as much as 0.005" of lateral run out by not indexing the rotors.
Dear uploader, do you guys ship to malaysia? Secondly, this particar brakes with 4pistons are just for the front, so the rear stays stock? Can the rear be the same discs as well with 4 pistons? Thanks
brembo owns AP and they've been in F1 for way over 30 years.
Neat video!
Looking forward to seeing more videos and hopefully some on road/track talk, as well.
Re: j-hook design, I think I remember reading that gases released from the brake pads are better dissipated, increasing friction, when clampin' down : )
what a great kit. Always had issues with stock brakes on my WRXs.

***** Not to mention better acceleration through less rotational weight

TBH, one of the most important features of a BBK is zero fade, ever.
Brembo who? APRacing is owned by Brembo
WOW didnt know that thx man. so cool
lmao oh sh*t i didn't know that either. thanks for the info
Brembo does the large production car runs. AP does the smaller racing and hi-po street stuff.
Yo does not kno!
Hahaha

Nice! Definitely looking to get some in the near future.
Hey love the videos, can you make a walk thru video showing the current state of the car?
Will this kit fit 17" wheels on wrx 2015??
I actually wanna know how badly the rotor is scoring from the removal of the dust shield
did this brake kit clear your stock bbs rims ?
nice video! Will the OEM wheels will clear the new calipers or you need to buy a new set of wheels with a different offset?
When replacing the brake pads, do you need to prep them in any way or do you just simply drop them into their slots?
Would these brakes be a track only set up, or would you have to put your oem ones back on for daily driving?
These are sweet vids man high production value!
Hey man, as far as the dust /heat shield goes its your choice, but the j hooks and the vents need to be facing the forward rotation. What you have done is the reverse, where the vents are not scooping up the air and the j hooks are not opposing the pads. You should consider changing this immediately
+Dj Hazard all rotors with angled fins, are to push the heat from the inner area of the rotor to the outter, not the opposite. why would you push the hot air towards the center of the rotor?
+oinkurrboinkurr because its comments like these that spread mis-information. Typical youtube comment lol
yea thermal engineering is a typical youtube comment
Well done explaining every step.
yes rotors are lighter compared to oem ,but calipers are heavy compared to oem.equates to same weight,,
Is this the same kit from the BRZ? Looks so similar.
Essex AP Racing Sprint kit is my favorite mod on my BRZ
are you guys building a track day wrx? if so why didn't you guys go with the sti?
Great DIY video, thanks!
Buying this is only for the front right? Do you also have 4piston brakes for the rear?
0:27 Actually I think most F1 teams use Brembo or Akebono (McLaren)... But certainly AP Racing are widely used in other racing classes :) And F1 brakes are tiny (since 13" wheels!) but very stout indeed! :D

Does this kit use a OEM dimensioned rotors and pads or is specific to the AP Kit? (I.E. is it an STI p/n rotor and pads?)
is it good too keep the factory shield with the AP (not for tracking) ?
Wonder if this kit cleared with RPF1 18x9.5 38mm on 2018WRX hmm
SubiSpeed , any videos/instructions on changing pads only? I just bought hawk hps from your shop. thanks
I'm interested, but how will this effect the torque vectoring and vdc?? Is it a drastic difference while turning? Don't want the car to over compensate or anything. On a curve the car's giving me a lot more credit then I should have with stock brakes
I'm almost 100% sure when you turn off all the Aids and switch to s# the torque vectoring stops.....
Hello, did you have to upgrade the BMC?
Wow what a great installation man. Great video. Stay safe.
Brembo who? Don't they own AP Racing? lmao. Gorgeous brake kit though!
What are the new stop distances with the new ap big brakes?
What rims are installed on the car?i want them for mine wrx they look nice
if your not a hardcore track enthusiast but still want to take your car out on the track without much brake fade whats a good set of brake pads that arnt to pricey?
Stoptech street performance or sport. They are same pad, just used to be called the former and then switched to the latter. (Or viceversa). Have them in my m5 and they work well under light track use/racing.
You need better fluid and I’d install stainless steel brake lines.
I'm new to tuning and i wasn't sure if i would need to buy two of these kits bc they only come with two disks and two calipers.
Just one kit is needed, as it only replaces the front calipers and rotors. There is not a rear kit available from AP Racing at this time.
SubiSpeed would it be alright to only replace the front calipers and rotors or would that cause a problem.
That's what we did and we've been to the track a few times since and we are still alive :)
Watching your other videos how come the brakes squeak all the time? Is it just when they are cold?
The pads we use are for track use. When hot they make no noise. If your car is more of a daily driver then there are pads we can supply in this kit that will be silent during daily driving and also provide decent track performance.
so would you say it would be a good idea to get these for daily driving? they should last a really long time with the thicker pads and the fact that it wouldn't be pushed hard as if we were on the track. Just a question so save the sarcasm or dickhead comments please.
These would work for daily driving, but they would not be necessary. We would recommend some upgraded brake pads instead.
What does the AP caliper and rotor cost? Also the cost on the Ferodo brake pads?
Thanks

+le Anthony No
+SubiSpeed can you do a video for the rear Ap racing brake kit 4 pis for wrx 2016?
More great videos. Keep it up
Is this kit realistic for a daily driver or strictly for a track day car?
This kit can be used both on and off the track.
So... this is only a front upgrade... what about the rear? nothing to match?
+Benito Samia (Bb) Upgraded rear brakes are available as well, however, most of your stopping power will be coming from the front.
+SubiSpeed what size rims would I need to fit a BBK?

Beautiful brakes.
What models are those brakes ?
Will this fit with stock wrx 2016 wheels or will i need spacers/new wheels?
This kit does work with all 2015+ factory WRX wheels!
I think you are forgetting that Brembo have been supplying brakes in F1 since the 70s
AP Racing has racked up about 708 Grand Prix wins since the 60s so they must be doing something right.
How does this compare to the brakes from the sti?

will this fit on my 2011 Subaru Sti

This guy knows fuck all about brakes
+Dj Hazard Hey dj fuckface shut the fuck up
+Massimo T shut the fuck up massimo fatfuck
Which one is better brembo or this ?
AP all the way.
Do these clear 15in rims?
In my opinion I think the top hat design on brembos is way better than ap’s
Where can I buy this kit? I have a 2013 STI

This will also fit the 2013 STI so good to go if you want to order a kit. :)
STi doesn't really need this, why go from 6 pot to 4...
How can I reduce brake fade with out doing all that? huh? anyone?
+Mad Hatter slow down i guess
Don't ride your brakes, puddles can warp or glaze your rotors with the quickness. Keep up with flushing every 2 yrs or 20,000 miles.
+Mad Hatter get better pads....
better brake fluid, upgrade the SS brake lines, better pads.
Yeah honestly you don't need all this unless your on the track. Stoptech makes a full kit that has better pads, rotors, and stainless steel lines. I also recommend a master cylinder brace.
Very nice.
And now the new ones are 6 piston calipers the size of a continent.
aint even got braided brake lines...whatisthis.
"serious track guys" has a WRX in the background... LOL ALso Brembo owns APRacing...

why would anyone buy this for the sti? It already comes with 4 piston brembo brakes from the factory.
+MrThePrivateer lol bullshit
MrThePrivateer Also the STI 60-0 is 106ft, the R 60-0 is 130ft. So please keep talking about how much better the brakes are on that car.

Does it still keep its abs?
ABS module and related ABS components aren't touched at all so I would assume so
