I have a V4 Sti that is used for fast road use. If i'm honest, i drive like i have Miss Daisy in the back 90% of the time. But, i do want to be able to track the car and not suffer with useless brakes.

I've decided to have a full engine build with a CDB capable of 600bhp done by Engine Tuner which is going to be a very slow time build.

My issue is, it'll be pointless without being able to stop.

I, like most want the AP/Porsche set up by powestation but i just can't afford or justify £2300 on a set of brakes.

I've been adamant that i wanted AP's due to their reputation. I bought a used set but unfortunately after sending them to AP i found out they couldn't be refurbed and were unusable.

I've considered Brembos from a newage but after lots of research on here it looks like they're not up to the job. It seems that they need to be drilled and refurbed every time you change your discs and pads.

I've seen the K-Sport gb run by Bren@Apex. For some reason, i've always thought of K-Sport / D2's being cheap copies. I have nothing to back this up of course.

I've already upgraded my wheels to 18x7.5 with an ET of 45 to take the bigger size disc and caliper.

My questions are, what do you recommend, why and where from?

i think the choice depends on your budget

K-Sport / D2's set ups are very good there are alot of members running them,with only good things to say about using them on fast road or track.SJ.

i had brembos as I have an sti and changed to d2 and they are much better.
im going to fit a rear set soon.

Thanks s.j

Would you think the 356mm is the option to choose? How do you think they'd compare to the 4/6pot AP's?

I know that's a lot to ask but i'm looking for opinions.

Markfey

Thanks tubs, you pic *****

It looks like a nice set of CDF droplinks and BC's as well

Are D2's and K-Sports very similar or totally different?

Hi there

Agreed on the Powerstation Porsche setup,which is pricey,but still you will need custom machined pads and they're not available on the shelf as for K-Sport/D2,which using AP pads and can use too AP Discs

About the D2,latest D2 have different design and mostly important they're seems are better in many ways,just using dust seals(in many ways is better,but can be this problematic if you will need rebuild as AP,Porsche/Brembo,K-Sport not using dust seals),plus using different pistons not like K-Sport,which using one size of the pistons

We are running K-Sport 356mm with 17"(low offset ET) and you should be able run on any 18",just due K-Sport or D2 callipers are NOT chunky as Brembo

I spoke to bren from apex at japshow yesterday and I forget the story behind the branding but they are identical ( 8 pot versions ).

stonejedi

iTrader: (51)

Markfey i know Jura runs a set TT also runs a set and as said above is very happy with the stopping power of them,to compare them with ap's,the spec of the K-Sport / D2's are reaching that level if not there already,its just that the ap brand has had more of a chance to prove themselves on the race scene as they have been in the forfront of racing brakes for years,plus there quality control and parts used in there build up of there calipers is top draw especially as there under Brembo,but saying all of that i would still purchase K-Sport / D2's and be happy that they would still do a job well and definately be fit for purpose I.E being used hard without fade.SJ.

Thanks all, it's really appreciated!!

I think i'll now be making two calls in the morning, one to bren at apex 356 kit plus bluestuff pads = £1045 delivered.

2nd

Ed@Japspeed 356 D2 (Not the latest kit) with sport pads £915 delivered.

At least my decisions have been whittled down. Thanks again.

he mentioned a scoobynet discount to me yesterday when I was asking about the rear kit so don't forget to mention that.

jura11

iTrader: (7)

Speak to Alyn@AS Performance,he is dealer too for D2/K-Sport and I would choose better pads,at least get PF Z-Rated pads


Jura

Thanks Jura, i trust your opinion.

I will endeavour to make 3 phone calls now

tubbytommy

I have never seen the red or any other colour in the flesh before until yesterday and Id recommend the black ones as the writing is milled into the caliper and on the red etc its just a sticker which I have to say looked a little bit cheap.


just personal thoughts but im a bit ocd on the look of my car

+1 Alyn is who i get the bulk of my parts from and as jura said performance friction pads are top draw,i would not waste my money on any EBC pad in my opinion.SJ.

jura11

iTrader: (7)

Hi there

We are run K-sport with DS2500 which has been OK,but still with PF Z-Rated pads braking is much better like on the road or on the track

If you are looking more for track days,I would speak again with Alyn@AS Performance about the best option

Jura

+1 always found ebc to be pants, id go for pagid personally as that's what im going to fit when I put rears on.

I've tried nearly all the options and currently have the powerstation setup, Very nice if a little dusty.

I had the ksports a few years back and found the standard pads to be lethal, once swapped over to something better they worked very well, but I found the bleed corroded after a matter months and went rusty, The alloy of which the caliper is made oxidised and looked tatty where the name was. The bells don't look as nice as the AP stuff.

Would I buy them again, NO

fawor

iTrader: (3)

thats a thing, you base on what You heard not what You owe and what... he bought standard pads with d2 kit
ive got ebc blue and You cant fault them,better than ds2500

tubbytommy

iTrader: (20)

and have had pagid in my brembos, very good pads if a little dusty and will be refitting front and rear when I put the rears on.


try and use google translate for us in the future,half of the crap you write makes no sense, but I suspect if it wasn't in pigeon English it still wouldn't.

jura11

iTrader: (7)

We're never tried standard pads,but I wouldn't put them anyway,just due not knowing how they perform on the road or track

About the AP or other makers,yes agree they're better but cost twice or thrice more than D2 or K-Sport

Second biggest problem of those AP and Porsche Brembo setup is reliability,they will need rebuild every year or so and price for rebuild is not cheap,are you tried to spoke with Ian or others about the rebuild price of them

AP Discs are available for K-Sport or D2 from Bren@Apex Performance or Alyn@AS Performance

I would buy Porsche setup,but for me is biggest problem,with Porsche I can use low offset 17",with 355/356mm AP or K-Sport/D2 I can use


Jura

I've run K-sport with DS2500 and they're been poor,we are now running PF Z-Rated pads and difference is like day and night

EBC BlueStuff I've run only on OE 4pots and I wouldn't run them,we are been disappointed with them and really for price of the EBC Blue... you can have PF Z-Rated pads


Jura

I used to swear by DS2500, I currently have the bluestuff in on PF discs in Brembo's. I've done Cadwell and Spa with them and I can't fault them either, very good overall and I fancy trying the orangestuff ones having previously never wanting to use EBC. I only tried the Bluestuff due to them being in when I bought the car.

Not sure where you got the idea the porsche set up needs rebuilding every year. They have the same style dust deals as the normal STI brembos, Which normally last for ages, The pistons are ceramic so will never corrode.

Don't forget these calipers come off a road car and are expected to encounter dust, road grime and salt.

I know the cost of the refurb as I got Godspeed to do these as I got these 2nd hand, It was around £160 and the seals are not that expensive (got a full set for £100)

With regards to cost, The Ksports have gone up over the years and by the time you buy decent pads your not that far off the cost of Ap's

The Ksports used to be around £8-900 cheaper than the AP but it's alot closure now,

As said, I've tried a few different brake setups over the years and wouldn't buy Ksport again. Would rather spend the extra

Lol at the comment that the AP and Porsche brembo calipers will need rebuilding every year , they are about the best you can buy !!
They will last for years before they would need looking at , it's only when they are used for serious track use that the outer seals can burn , but that it only after continued hard track use.
Apart from that in my opinion you won't get better.

Now I have nothing against K sport calipers , we have sold a few kits , and painted quite a few calipers so have stripped them down completely , and they are not as well designed or made as well as AP or Brembo , which reflects in the price compared to the other two makes , so please don't try and make out that K sport are as good as AP or Brembo 6 pots as they are not.

OK Try buy new 355mm set of AP Racing 6pots for £800 without the pads,I'm pretty sure you can hardly find them for this price

About the reliability,how much per year is used yours car,are you using yours car in winter and on the track?

Maybe 1 year has been OTT,but still will needs to be rebuild'd,when time will tell,sooner or later,they will need

We are using our K-sport like on track or on the road and has been faultless,agreed on discs they're poor


Jura

Ian

Agreed my 1 year can be OTT,but still will needs to be rebuild'd sooner or later

Nobody never tested them on the same car or any company tested them in head to head,which is shame

This is only my or yours opinion/people who use them how they're are

If they're so bad or non comparable with AP/Brembo,people will never use them on TA and other events


Jura

How many of the TA cars pay for those brakes?

RCM use the APs and they seem to do ok!

If your sending big money on a motor I would go with the APs, getting my rears fitted in the next few weeks and had the front for 4 years without any issues. From the sounds of it you would be happy with any if them tho

I am running with brembos, performance friction discs and pads and PF dot 4 race fluid, the car is used for track days, hill climbs, sprints and is used daily, /.they have been brilliant. Discs are now over 3 years old and are exactly half worn with no warping, on my second set of pads.
