I don't rate the ds2500's that highly for the price.

They are not a bad pad,and certainly better than mintex i just expected more from them, i think your as well going oem or ebc and the blue stuff are way better for similar money.

Dont get me wrong the Ksport/DS2500 setup was very very good and got abused on track and never let me down but i feel my current setup just feels better even with the bug being a heavier car.

AP's are far better than the standard Brembos. As previously said they are billet alloy and don't retain anywhere near as much heat as the Brembos do. They also have neat little tricks like pistons that are drilled so they don't transfer as much heat to the caliper and fluid. We run 308mm ones all round on a group A Escort Cosworth rally car and they are the dogs bollox, even on tarmac events when we should be running bigger ones. No fade, ever and that's on events like Otterburn and Jim Clark.

What pads do you use and how much do they cost?

I'm only going to say that the AP set-up on mine has astonishing initial bite and feel, that's after upgrading from Brembo + PF !

P.S. Worth it yes, if you need it

Wouldn't be surprised if Mark uses Carbotech XP's on his Cossie........ I've got some XP8's and they are really a bit much for driving around Carlisle LOL

It depends what calipers your referring to , the road calipers are not billet , they are made in the same way the Brembo STi calipers are made , from forgings , if your looking at the AP billet calipers , with titanium pistons which will be drilled for less heatsink , then your talking thousands of pounds worth of calipers , these are a different kettle of fish and should not be compared against a road caliper.

The Gold STi calipers are really not that heavy compared to a road AP 4 or 6 pot , its the Brembo discs that weigh a ton , with good pads fitted , there wouldn't be much in it performance wise of the STi calipers and 326mm discs and the AP 330mm 4 pot kit , with the pads being larger on the STi setup , the brembo's might just have the edge , where the AP's gain is in the weight of the 2 piece disc arrangement , but then you could shed some weight fitting 2 piece discs with the STi calipers.

If someone with an STi with the gold calipers fitted phoned and they were asking me for advise about whether to fit AP's instead , I would recommend a 2 piece disc and good pad and retain there brembo's. I would only recommend a caliper change if they were going for the AP 6 pots

If someone with a classic , was looking to fit either the STi setup or AP setup , and had to buy everything , then it would be a close call on which way to go , and based on what the customer was looking for , budget and use

Either DS3000 or Mintex F4R or F6R.

I ran a classic with ap 4 pots in timeattack and they were very poor, over shot corners regularly. I also ran a classic in timeattack a year later with brembo and carbon discs with carbonne lorrane rc6 race pads and IMO there is no other brake package combo that I would want to try instead. With this set up I could regularly lock the fronts at 140+ with r888 tyres.
In short IMO it's all about choosing the disc and pad for the purpose.
As for calipers IMO your splitting hairs

It would be good to get some real time testing done with the various configurations of caliper, disks and pads to see which indeed are the best. Some thing like 5 100-0 mph stops in a row and some lower speed stuff say from 40-0 mph. It's fine people saying "these are far superior to those" but where is the proof? If someone has just spent 1800 quid on a new brake setup of course they will say it's awesome.

more to do with the discs and pads? carbon discs need some heat in them to work so no good for road use surely?

Ian, do you happen to know the weight difference between your two peice discs and one peice discs for the Brembo calipers?

I'd like to know too, as I weighed the STi ones at nearly three and a half stone

When i was buying brake upgrade for my classic did some math and realized its not much more to pay for new AP 4 pot 330 set up since if you buy STI calipers(350-400) and the add Ians two piece discs (356) and some decent pads (150-200) you end up not so far from AP kit........not to mention if you ahve to refurb sTI calipers.

I've not run brembos myself but I know plenty of people who have suffered with brake fade when pushing hard especially on track,

I took my blob JDM 360bhp to Anglesey TD and the Brembo's just cooked big time - pedal straight to the floor. That was with a new (ish) set of track specific pads

Never let me down once on the road though
