If you was going to buy new brake setup and option were only either D2, Pb or k-sport which would you choose?

 

As far as I know k sport and d2 are the same? I've got the d2 8 pots and with better pads they are very good.

D2 and ksport ars the same

 

And they are rebranded ksports too.

 

didnt know that............

 

They're £1200 though and neither of above lol.cheers anyway

 

The new ksports/d2s are now 6 pots so they are based on latest versions.
the older versions are the 8 pots

 

The same,really? What size discs you use with the D2 8pots and what size wheels?

 

Jesus you just ask the same questions....

330mm will clear 17s

356mm require 18s

 

hhmmpppffffff learn summat everyday.how are you finding yours tubbs? what pad choice did you go for?

 

Does this mean the 6pots are better than 8 pots if they are new version?

 

Thanks,is there any differences?

 

They are fine on the road i use ds2500s
Better than my brembos were but they are 356mm.
im fitting some rears soon

 

good stuff,i used to have ds2500 pads on other models but the brake dust was quite bad,is it still the same? ive just aquired some rear brembo's that will be going on when i put my 6 speed in over xmas

 

Google


the same.

 

Tommy calm down mate! I dont keep asking same questions,I asked imprezaworks what size disc & wheels he has not what can I have!?

 

Yeh quite dusty but i have matt black wheels now so not so bad

 

happy days

 

I have done in the past and what I can remember I read something about internal/external dust seals.one has them and one doesn't??

 

the newer 6 pot versions have different dust seals but it wasnt a problem on the older versions anyway.

dunc has run both 6 and 8 pots on his time attack car without issue so they are more than adequate for a wrx.

 

Where can i get pads for the 8 pot k sports? The ones that come with are utter garbage Sorry to highjack

 

i would try alyn @ as-performance or ian @ god-speed brakes

 

Thanks buddy

 

no worries

 

I think the difference I read about was between k-sport and pb. Wonder why they replaced the 8pot for 6pot?

 

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.

 

Depending of where the car is used... Some had problems some didn't ...
Race cars are being overhauled quite often too including brakes... Or the sponsors are just giving another set of them , probably cheaper option

 

Jesus mantas he cant remember what size fits what.
its a wrx road car ffs any of the above will do

 

You are reading what i wrote wrong tubbytommy. I can remember fine thanks! I asked imprezaworks what size disc and wheel He has on He's car with the D2 8pots He has. Nothing about what wheels match what disc caliper etc...
