981 GTS brake disc life?

[SV_WDC]

Couldn't find any answers with the search options....

How many miles can one expect out of a set of 981 GTS (or S given they're the same) brake discs?

Understanding it matters based on how hard you drive it, but would be good to understand from existing owners.

Mine was on 27k miles and needing pads imminently.

Reading OPC told me they only change pads and discs together, as there will be a lip on the disc.
Sold them the car, so never had to deal with it.
That was with very little motorway miles.

Mine was serviced at 28k miles and had a reported 50% wear all around. Admittedly the previous 10-12k miles were a lot of motorway. It's on 31k now, and had a few track days, so expecting needing to replace them soon.

40k + pretty normal.

Inner surface can corrode too so something to keep an eye on.

Thanks all, and that's good to hear.

Can I clarify, is the reference to 'inner' the opposing side of the disc is tricky to see without jacking the car up (1) or the gap between the two disc plates (2)

Great, thank you

My fronts discs and pads were replaced at 26k miles, but the car is ex press so had a hard early life and I drive it hard too. Rears probably not far off now at 35k

Any idea as to what it costs to change the pads and discs at a Main Dealer cf an Indy ?
Thanks

[Devilspoke]

£654 was the line item cost on my big service bill for front discs and pads at an independent

This is called talking up the bill. There should not be a significant lip on brake discs once the first set of pads have been consumed, but discs can and do corrode if parked up wet or worse, salty wet. But if there was ? the new pads would rapidly settle to the slight lip shape.

Brake discs are end of life when they are either cracked between drilled holes, warped, badly corroded (often on the inner face) or worn down to their minimum thickness, by which time there will be a deep lip.

My local indie got the lips machined back on my GT4. I hadn’t trusted their local machine shop to do a full disk skim, but I needn’t have worried. Absolutely exemplary work. The disks were absolutely miles off minimum thickness, but the lips would have been very noisy with new pads.

Mine will get new discs and pads this winter. 67k on original set.
