me

front and rear upgraded on a MY00 wagon, from 170mm sliding rear\280mm four pot Subaru fronts to 190mm two pot Subaru rear\325mm two piece floating disks four pot Brembos (not the heavy horrid OE sti callipers either), and braided hoses.

'felt' nicer but that was probably to do with more aggressive pads...the real difference is in repeated stops from three figure speeds; reduced fade due to larger and thicker disks. The end

oh and they make the car look cooler "because race car"

me too, from oem brembos which were ok, to two piece discs and ferodo pads on brembos which were very good to d2 356mm 2 piece disc and pagid pads which is also very good, not much in it between d2 and 2 piece brembo combo though until you do very hard driving then the increased size seems to reduce fade........

so id say bigger brakes are better but not until you drive the car hard, but its better to have the brakes sorted before you find out they aren't up to the job..

What's that for? You've done it, meaning you haven't just been a 'reader'

I've also been through the standard WRX brakes, moved up to an STi with standard Brembos, upgraded discs & PF-Z pads on Brembo callipers, and now have a K Sport 356 set up with PF-Z pads.

What I will say to all the doubters is, with the wrong pads in, the K's are worse than the standard Brembos. As said... "Brakes are nothing without combination!"

I've also 'done it'.
Your last point is a little ambiguous and confusing.
Who are the doubters and what are they doubting? Are you merely confirming their doubt by saying the alleged upgrade of the Ksport kit is inferior to the standard kit? Or are you saying those who doubt the veracity of upgraded kits must be prepared to chop and change?

Blue by You

iTrader: (23)

What I was trying to say was, that if anyone has tried brake upgrades and was disappointed with the results, you need to get the right combination to have the desired effect.

Maz

iTrader: (34)

I gathered I was only being facetious
However it's a bit of silly if Ksport are selling kits that are inferior in braking to the standard Brembos That smacks of poor packaging and ripping customers off. Why should you have to throw away new pads and pay a couple of hundred for some more. Surely the purpose of an uprated kit is to be uprated not uprated only after disposing of the supplied pads and buying your own. In my experience there is no substitute for APs. Having had six pot fronts with 362mm disks and four pot rears on a erstwhile Evo, I can say braking was phenomenal. No fade, no fuss and no drama. Handy when you're repeatedly braking from 150mph.
Currently after a little experimenting and almost buying some Ksports I settled on PF disks with Carbon Lorraine pads. Perfectly adequate for my needs and more than capable of handling whatever I throw at them. Not tried them on track yet though.

tubbytommy

iTrader: (20)

they don't come with pads, you have to specify which pads you require, some are good some are pad, nothing to do with the calipers.

Maz

iTrader: (34)

Apologies, my mistake. I thought they were supplied with the inferior pads.

bustaMOVEs

iTrader: (31)

Hey maz you turned to carborn Lorraine's then? Which ones?
Good man, you won't be disappointed and don't worry about track I can assure you they won't fade if using proper fluid try making a brake stopper for better feel.
Keep your wheels clean with good quality wheel cleaner as I know your wheels are white

And as for the k sport pad question I know that k sport supply their own pad (maybe k sport pad not sure) but have heard its rubbish. So best getting better option with the kit as I know they do a few, the k sport pad come free with kit afaik.(or they used to)

tubbytommy

iTrader: (20)

they no longer come with the kit, as you say they are rubbish, k sport have changed uk suppliers to apex I think and he told me at castle coombe when I was discussing my rear set up they only supply a choice of aftermarket pads now.

bustaMOVEs

iTrader: (31)

Ah that will be it then as I know they used to supply a free pad with kit then pay extra for options. (because they were crap )
Yeah I know apex is in Bradford your favourite city

tubbytommy

iTrader: (20)

yup that's correct, the free pad is no longer an option I believe.

AndyBaker

I'd say that was pretty much about spot on.

I have had standard WRX brakes (2003),
Godspeeds discs with kevlar pads
Godspeeds BBK (335mm) with ferrodo ds2500 pads
K-sport (330mm) with ferrodo ds2500 pads
K-sport (330mm) with Bluestuff NDX pads

Personally, I think the complaints about the WRX brakes being rubbish have more to do with the wooden feel and lack of initial bite than the actual performance. They're also not over-servoed like some other manufacturers brakes, which leads people to think "omg they're crap", because they have to step harder on the brake pedal than in another manufacturers car.


I don't think anyone is arguing about whether or not uprated brakes are better at track etc, but rather that within the parameters originally specified (i.e. single high speed stop), uprated brakes make virtually no difference.

iTrader: (3)

Going against the spirit of this thread...

I'd just point out that at no point did I fit bigger discs, although the AP discs may be thicker

Henrik

iTrader: (5)

Just to add, my personal favourite out of my options above are the k-sports with the bluestuff ndx pads, but that's because my car is track only.

Blue by You

iTrader: (23)

Just for clarity's sake, I bought my K's 2nd hand, but little used. I won't disclose the pad that came with them as that will start another debate which is (and has been) the substance of many other discussions. Suffice to say they are truly dreadful, poor cold bite and not much better when hot.
As I said I now use PF pads suppled by AS Performance and they are top notch.

tubbytommy

iTrader: (20)

why not fit budget tyres too, after all, they just go round and round touching the road. im sure a set of whoflungdungs are fine going in a straightline at 50 mph just like a set of good years

bustaMOVEs

iTrader: (31)

A high speed stop would be down to pad compound to make it stop quicker in that scenario.

bustaMOVEs

iTrader: (31)

Just say the make of pads ffs it will help others to make an informed desicion.

I could guess though

Henrik

iTrader: (5)

Bustamoves, no it isn't, it's down to the tyres. How can you possibly brake harder than braking so hard that your tyres lock up? You can't, and it's possible to lock the tyres up even with standard brakes from high speed. Hence, having even more braking power available will not make you stop faster.

Tubbytommy, er, no that would be a terrible idea as that would make both your braking and handling worse. Are you misinterpreting on purpose?

Honestly mate it's been done to death and there are as many people swear by them as swear at them.

And you're probably right

tubbytommy

iTrader: (20)

of course I am, everyone modifys differently.
personally I would never run budget or mismatched tyres but you would be amazed at the amount of modified imprezas I see at shows running budget tyres.

brakes,suspension and tyres are all a major part of a performance car.

bustaMOVEs

iTrader: (31)

henrick-
Of course the tyres I forgot, but assuming you were running slicks that are harder to lock up, it would come down to the pad compound, as that compound at say 150mph will make most of the braking time up at top end and reduce it quicker to a slow as appose to a rubbisher pad the dosent have as much bite.

You need to try some more pads, I see youre a ebc boy

Kevlar? Comline?
