Mate you only have a wrx and people with far more capable equipment are trying to give you advice.
Aps are best.
d2\ksport are the same but 356mm will require 18s.
brembos will be as good as brakes above.
Make sure you have decent pads and tyres.
and the im a driving god bullsh1t is dull...

Quoting John Felstead:
With regards to the K sports, you may have 8 pots, but the surface area of those 8 pots is almost identical to the WRX 4 pot and less than OEM Brembo's. The K sports have two small leading pistons working on the area of the pad that provides the main performance of the pad, which will give less bite from the pad than the larger leading 4 pot piston. You will get a better performance from a 6 pot caliper with properly stepped differential pistons. The equivalent D2 6 pot caliper has larger piston surface area and a larger leading piston than the 8 pot K sport, so gives better initial bite and more brake force for the same pedal pressure.
AP 6 pots have better differential piston sizing than both the K sport and D2, with 3 piston sizes in use to ensure the pressure on the pad is well matched to the requirement to provide less taper wear and give a better match to the required pressure increase as you move away from the leading edge of the pad, which is where all the work occurs. The D2 6 pot has 2 small and 4 large pistons per caliper, so the pressure required is less well distributed than the AP, but not too far away, the K sport has 4 small and 4 large pistons per caliper, which gives a less even pressure match across the pad length. This means the AP will give the better brake feel and modulation, with the D2 6 pot next, the K sport a bit further away.
With regards to piston surface area, pad surface and the total brake torque resulting from that, on a 330mm disk the D2 6 pot gives the most total brake torque, K sport next and then the AP 6 pot last. None of these give as much brake torque as a Brembo OEM caliper on a stock newage disk. Even a 356mm AP 6 pot kit gives less brake torque than an OEM Brembo setup. Where the AP, D2 and K sport win is in handling the elevated temperatures seen on track.
There are differences throughout the Subaru range with regards to the master cylinder bore size, and also pedal ratio, this will also influence the amount of force required at the pedal to give the required brake force. So a brake kit on a classic will work differently on a Newage STi, Newage WRX or Legacy. And we haven't touched on brake balance matching for the rears, or the way the ABS system will work when you change that balance.

You are talking ****e
piston sizes ap's Ø27.0 x 2 / - Ø31.8 x 2 / - Ø38.1 x 2
ksport 8pot φ26、φ26、φ26、φ31- where the **** are 2 large and 2 small pistons than?
front ksport 6pot φ36、φ31、φ26.4
ksport pad is long and way bigger in cm3 than brembo and wrx 4pot caliper, 8 pot design matching pad perfecly around and surface is over 10% bigger than ap's
both are non monoblock design and both are way better than brembo wrx set up, first pads are bigger and discs to.
new 6pots ksport arent worth a money especially with 330mm disc
money :
ap's with ap discs close to 2k
ksport 8pot -900
alcons monoblock 1.5k-problem with track/road pads
best bet -brembo zr zl 18-powerstation kit, monoblock 2k-problem with pads to
winner -ksport 8pot
for ap's money You can add ksport rear 356mm discs with 4pot calipers
im sure ksport 8pot front and rear both with 356mm disc will do job better than ap's with front 355mm and rear 4pots 330mm discs for half a money
the funniest thing is a lot of ap users put aftermaket discs(cheaper kit buy) ,take them on track and -Surprise pads warp discs.
buy cheap buy twice
ksport disc is used by some ap owners - why ,dont crack so often
next most users from this site use cp7040 caliper which is massive and heavy and is designed for road not track,on track should be used cp55xx range, lighter ,with antilocking springs etc.
had them three ;wrx 4pots, sti brembos and 8pots and stopping distance is unbelivable with 8pots,from 40mph you can brake few metres before corner and you think, **** me 10 metres to late but no, they will stop you just before turning.
my advice wait till before christmas and try ebay, last year was offer for ksport 8pot- 720 pounds few days only, later was offer for 810

Unless you've done extensive testing and comparison one product to another , who are you to believe you ? I'm sure statements reminds me the recent debate of a wrx ppp vs sti
A lot of AP users buy cheaper discs/kit ... you already bought a cheaper kit then my AP's ...you bought K sports
, most people i know who's got AP's have got them for a reason and these no cheap stuff with brakes afaik used PF discs.... Now grow up and stop being a ***** , put your constructive comments instead of efin every 2nd word...

Oh and scoobyjim your being a bit of a **** mate, if you go and spunk £1200 quid on D2 or ksport when you could have the AP 6 pots in the for sale section for £900 or New AP 4pots for the same as the D2's then you truly are mental.
But like I said in your other thread," it's not my money so I don't care"

See you're the one that doesn't listen or read properly in you're case! My first thread was what brakes are too big and will create adverse affects? (Not antthing about what wheel sizes will fit what brakes) my second was who do people think the best mapper is,I would like 400bhp but doon was told my vf35 is not capable of that,to which I replied I would like it turned to as much as is possible from it. I wanted my engine built strong for reliability not to use all its potential.same with gearbox,I wanted it to be as strong as I could have it for reliability more than getting maximum out of it. I dont drive fast n furious everywhere, but when have my moments I want to be able to stop

Hi there
Go with bakes which you can afford,really don't take shortcuts on the brakes
We are running K-sport front and rear,but we never have fade on the track or on the road with them,with previous pads DS2500 we are never been 100% satisfied,due this we are went with PF Z-rated pads which we are prefer mostly
OE 4pots are poor for New age WRX,I would replace them right away for Brembo at least
Comparison Brembo/K-Sport or D2 and AP will be always and always will be war of the words,some people still think their brake setup is best,but actual testing never been published or tested
We are went first time with K-Sport and we are happy,if I would buy them again,yes

We are running K-Sport 8 pots 356mm at front with PF Z-rated pads and at rear we are running K-Sport 6 pots 330mm with DS2500
PF pads what we are running(Z-Rated) not ruined our discs,not sure how it possible you are ruined discs on yours Brembo, what discs you are run
Do you run previously some cheap discs(drilled and grooved) or do you run proper PF discs?
