c) what are the issues with say changing my front pads to some more specialised ones, while retaining the standard rear pads until they're due for a normal change (i don't want to bin perfectly good rear pads unless i absolutely have to....).
Leading evidence: 'Replace (i don't want' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace (i don't want' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I had new front pads and discs (OEM) from my indy when i bought the car, and the pads have lasted for 5,000 miles of road use and about 100 miles of track use before the wear light illuminated.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Collective wisdom please!
I've started to doing track evenings on a reasonably regular basis now, and it would seem that I'm eating through brake pads on my 996 C4S. I had new front pads and discs (OEM) from my indy when i bought the car, and the pads have lasted for 5,000 miles of road use and about 100 miles of track use before the wear light illuminated. I think the discs are okay, but cannot really tell tbh.
Anyway, so my questions are:
a) is this wear rate normal? bearing in mind that even on the track i prob only brake at 80-90% of what i could in order to save the brakes a little
b) are there any recommendations for non-standard pads from anyone? i'm not fussed if they stop me any quicker as the brakes on the C4S are monstrous anyway, but i would like them to last longer and save me some money!
c) what are the issues with say changing my front pads to some more specialised ones, while retaining the standard rear pads until they're due for a normal change (i don't want to bin perfectly good rear pads unless i absolutely have to....). presumably, if the front ones don't really grip more, but are just more hard wearing, there's not really a problem?
any help would be v much appreciated!

addendum:
regarding disc wear, does anyone know (or know where i can find out) exactly what the minimum disc thickness is (for front and rears) on a C4S with standard discs before i have to replace them? i'd like to be able to measure it rather than just have to go on what a service guy tells me.
Could it be that your independant didn't put Porsche pads in? - 5k miles is much too low in my opinion.
My guess is that the discs can wear down by 2mm - that's certainly the case with my car. Somewhere on the forum is a technical note about disc wear, both in terms of thickness and the fact that any cracks should not exceed 5mm in length(that technical note may only be visible to Club Members - if so maybe you should join?).
EDIT - here's a link to the info about disc wear (thanks to Richard Hamilton):

thanks for that info, v useful to know. I'll have a look when i get home, but i'm pretty sure they're okay at the moment
Is there any confirmation on the thickness of the discs question? I'm sure i can locate a micrometer to have a measure of them.
The info is in the Member's Only Technical section of the forum, but especially for you: https://www.porscheclubgb.com/legacy/clientftp/Register/996/tec_996_brake_wear_limits.pdf
i find that compared to what i thought, track days are quite easy on my tyres. maybe it's the 4WD? AIUI, when the rears start to lose traction (i.e. skid/slide, which is when you really wear the tyres), it shuffles torque to the front wheels. plus, i don't powerslide like a hooligan or anything, or deliberately spin up the tyres. well, most of the time
