This is the advice I got for my 944 turbo which has the same problem on track.
Castrol SRF Racing Fluid (or their synthetic high performance brake fluid)
Porterfield, Pagid Blue or Blue Hawk pads
Braided stainless steel hoses
Ensure you have good cooling to the brakes - ducking from demon tweaks

C`mon Scottster, where are you on this one, didn`t you go though this with those big yellow Brembo things?

Can't give any specific recomendations for the 968, although on 911s pagid blues or Porterfields are well recomended, plus the normal higher boiling pint fluid & braided hoses etc etc, however I assume the car is not MO30 & thus you are not running big reds- just the old standard 968 jobbies.

I think you will find that whatever you do you will still feel that are lacking in ultimate fade free retina dtaching stopping power on track, & your best be may well be to investigate either a big red option of some type- lots of variations, or as Scottster did & look at another big brake conv think his are AP.

Few replies for 968s so I can give you my findings from a similar 944 S2 and an M030 944 Turbo (290bhp). Background is I've had the S2 for nearly six years and 50,000 miles, and the Turbo for two years and 30,000 miles doing about 4 trackdays a year. I use full slicks on tracks for the past two years (when its dry )

I've always used plain undrilled Zimmerman disks and never had any problems (apart from slight surface rusting on the unpainted hub - grey primer cured this). They are between £40-£50 depending on S2 or M030 and the fronts last about 10 trackdays

I use standard road pads from German and Swedish car parts and they currently turn out to be made by Pagid (not blue or orange or whatever), though they could change their supplier at some point I suppose. £40 a set last time and the fronts last about 4 trackdays.

I tried EBC greens a few years ago whch cost £57 on the S2. They seemed no better or worse than standard but did reduce dusting incredibly. After four trackdays I noticed that my disks were scored so I won't use them again.

Until this year I've only ever used standard Dot 4 brake fluid but I change it at the beginning of every year and bleed it every couple of trackdays. I put in some Castrol Response last year (slightly higher boiling point) £9.99 a litre at Halfords.

I've never, ever had any sort of fade at any point just using these standard setups and thats even when doing long 30 min stints in summer on slicks. The M030 car does have ducted cutouts in the front bumper as standard (which must help) and before that I did attach some ducting to the underside of the S2 straight into the back of the disks when I first switched to slicks.

My personal advice is keep everything standard but maintain it well, and do a good cool down lap at the end of every stint, making sure to leave the car in gear with the handbrake off afterwards. If you do have problems try a better fluid first, then pads etc

I tried various pads on my 968cs including, Carbon Metallic Z compound (ok) GreenStuff (too soft) and Redstuff. I don't normally use EBC pads but the Redstuff worked significantly better than standard. I also uses braided hoses and SRF brake fluid.

Pads: I've had good repsonse from both Porsche standard and Pagid Blue's. I have friends who swear by Mintex 1144's or 1155's, but they don't last anywhere near as long as either Porsche standard or Pagids. I've though about trying Mintex or Porterfields, but the Pagid's just refuse to wear out! :-P

Disks: Porsche standard (OEM Zimmerman I believe), every time - v.good stuff. Need bigger brakes? Go for bigger porsche calipers and disks, there's _plenty_ of options.

Seriously, the biggest and most effective change you can make to your braking hardware is stainless braided hoses and decent racing fluid (>500F wet boiling point - real big difference!), and the second biggest change is to change your braking technique to move away from "comfort braking" which over-stresses your hardware.

Have lots of fun!

Scottster put AP four pot upgraded calipers/discs on his car. They look fantastic and work well - they are the 5300s I think, as fitted to the Nobles. If you talk to an AP dealer (such as BG Developments in Northants) they should have 4 and 6 pot options, although check clearance as 17s may be fine for the 4 pots but not sure about the 6s (upgrade to 18s?). Price is about 1300 GBP including pads, discs, braided hoses, fluid, calipers etc. (front only).
