D2,Pb or k-sport brakes
#182
But haven't you mentioned somewhere yourself about subaru 4pots not being much good? Or am I mistaken? Only get fade after heavy braking mate like 100mph to around 40-50mph. After say the first hard application I dont feel confident at all with them
#183
Look I know your only kidding well I hope you are but I have never asked what wheels the brakes fit under.when I asked what disc & caliper is too big,I meant what is too big a brake setup that it would create too much force on the front. ie the 400mm discs to which tubbytommy replied they wont fit under 18s.which is good to know but in all honestly I wasnt asking that! That seems to be the problem on here that too many people run away with the thread and dont concentrate on the actual original question in hand..

Yea but im not actually asking what brakes I should get im asking what people think? There is a difference! Sorry if you don't feel I have explained myself well on here,please bear with me im new to this forum business. I dont even really like txting/messaging etc.lol but I do like to research things,whether you say I listen or not,I assure I do (even though still make wrong choices sometimes,im only human lol) and appreciate everyones feedback,well the nicer ones lol.(unfortunately this leads me to having to txt,I am much easier to understand & get on with in person,as im sure some of you are and you might believe me if you met me and maybe had seen for yourselves ).

Ok, that is funny
To the OP, I have Brembo's with PF discs and Bluestuff pads and 888's. I haven't managed to get brake fade at Cadwell or Spa, my friend has a similar setup albeit on an Evo 6 and DS3000 without fade and he brakes hard and late as anyone round Cadwell and has taken mine out and couldn't get fade.
Just to add, there was a set of AP 356mm Cp7040 on here and 22b last week, they only needed new pads £1100.

This is my (AND OTHERS) point/problem. ^^^^^^
How many times have I now told you that Brembo's are a massive improvement over the pants 4 pot subaru calipers. MASSIVE. I've had absolutely no brake fade on my road car with Brembo's, but loads previous with the old subaru 4 pots and different disc/pad combo's.
Honestly, you say you don't repeat yourself or ask the same flippin questions. Evidence YET again above!!!!!!
ARGH. GIVE ME STRENGTH!!!!!!!

basically your brakes (4 pots) are crap, brembos are better and so are ksports/d2 not a lot to choose between either.

for the record and forget everything else, what do you want to know??
#193
what he should have written for the title is.
im a street racer bruv, my four pots keep catching fire and i want some ksports, i dont care what advice you offer me i want ksports, are ksports any good,should i get them,i want ksports, are ksports good, im getting ksports...........

#198
At £800 or so for complete setup i would say they are budget personally,as are d2 & pb. Brembo are second hand for budget money. I havent rejected brembos,just getting views what people would buy from my budget range
#199
Mate im listening.ap are the best etc etc,but when will people realise its not what I've been asking
#200
right jim i have a newage sti which came with brembos, they are very good with the correct pads but have issues with the bolts snapping when you remove them to replace the discs and they need helicoiling.
when i went to replace my discs the above happened, rather than get them helicoiling,buy new discs and pads and repaint it was the same price to replace with d2s which are identical to ksports just a different sticker on the front. so i did.
as i run 18 inch wheels i bought 356mm kit and i have to say its slightly better than brembos but not vastly so and i put that down to the increased size.
so for me id go for ksport/d2s and thats from someone who has tried both setups with identical pads and you also get braided hoses in the kit.
and change the brake fluid at the same time.
does this answer it ???
and just to add if the brembos hadnt got above bolt issues would i have swapped them?? no but it was cost effective to as i sold on the brembos

Well thats the thing I cant drive it too hard because of brakes,they do work quite well before one or maybe two heavy stops. No one mentioned built up area pal
#204
saying things like this wont win you many friends on here mate-it is a bit daft
regarding the brakes-heres my 10p worth...........
cost isnt really the issue BUT what you get for your money is-let me explain
a USED (nearly 10 year old) set of front brembos will be about £450 then if you have your head screwed on you will want to at least stick on NEW uprated discs and NEW pads (£550-ish)
http://www.godspeedbrakes.co.uk/~god...?id_product=28
http://www.godspeedbrakes.co.uk/~god...?id_product=86
along with a decent fluid (£20) and whilst your doing it you may aswell uprate the hoses too (less than £100)
so thats an outlay of (give or take) £1100 which will be fine for a fast road car BUT for not a great deal more money (£100 or so) you can have a a NEW k-sport kit with NEW (not 10 year old) calipers not painted in flakey pikey gold paint
see here
i based the price on the kit with ds2500 pads
http://www.scoobyworld.co.uk/catalog...oducts_id=2146
if the difference was £500-£600 then i would suggest brembos but as its the price of a night out then i suggest the k-sports
im not saying that they give better stopping power as i dont honestly know-what i am saying is surely something that is new is better than something that is 10 years old
#207
I'll be polite and repeat myself ... this is all you need to know... Trust this peace of knowledge..... This guy has been given to test these brakes Ksport vs D2's vs Ap's.......
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.

Not you aswell mate. Fudgey please read my very first post on this thread and also read the very first post on my other thread 'how bigs too big' I havent asked the same questions mate
