After 3 track days plus 7000 street miles, I got a break wear light. Question: Any recommendations for pad replacement- - OE or after market? I will track the car no more 6 days a year and don’t mind brake noise with aggressive pads.

I've heard great things about Hawk in older Porsche's, nothing on 992's yet.

They list these for the Carrera:

Hawk Street Performance Ceramic Front Brake Pads (992 Carrera)

Sale
$205.27
$184.74

Designed to fit:
  • 2019+ Porsche 911 Carrera Base (992)
Product Details

Performance Ceramic Z Compound

Performance Ceramic is engineered to reduce brake NVH (Noise, Vibration and Harshness) creating a quieter performing brake pad. Furthermore, the ceramic brake pad formula has a linear friction profile that allows your ABS brake system to work more effectively. With Performance Ceramic you can expect reduced brake pad wear, lower dust output levels and a rotor-friendly brake pad.

  • Increased Stopping Power
  • Increased Rotor Life
  • Extended Pad Life
  • Ultra-Low Dust
  • Extremely Quiet
  • Stable Friction Output
Specs:

  • Pad Thickness: 0.668mm
  • Temperature: Min (100F) - Max (650F)
  • Optimal Temperature Range (100F - 450F)

This is a follow up to my brake wear light. I replaced the pads, both front and back, but found that the front pads still had about 50% wear left and the rear pads were down to about 10%. Seems opposite of what one would expect. I've got rear wheel steering, so wondering if the combination of the rear wheel steering and stability control cause the rear brakes to work a lot on the track. I track in sport plus and leave the stability control on. Any comments?

Traction control could be the culprit. It’ll wear the rear pads mighty fast. I write this from the pit of my local track after having done the same as you to my 992 CS at 4800km!

The rear brake pads on 992 wear out very fast because of the PTV+ (the Porsche Torque Vectoring system). You can NOT turn off the PTV, unlike the PSM. Even when You have turned off the PSM completely, the PTV will still work. What PTV does is it applies each of the four brakes selectively (sometimes even when You are NOT braking), attempting to correct a perceived instability. So, for example, during hard cornering, the PTV will react to perceived "loss of stability"and will apply the INSIDE REAR brake. In tricky road situations, the result is that the car's rear end gets "tucked in" while cornering and an unwanted slide can be prevented. In track situations, or when You WANT the rear to slide out, the PTV will still attempt to stabilize the car and will apply the rear brake, regardless if You want it or not. I have had the rear brake pads totally worn out after just about 3 or 4 track days, while fronts still quite good. The rear brake wear will be especially heavy if You happen to just do some drift training on wet or on snow. The PTV does not "know" and does not care if You want the car sideways just for fun. On the public road, the system can sometimes save a foolish driver from a crash. On a track or skidpad, it works just as well - You just need to keep a stock of extra rear brake pads....

Indeed.....I wore out my stock rear pads in 2 days at Sebring....now replaced all four corners with girodiscs and pagid yellows....thanks for the details on the PTV....it is helpful to know you cant switch it off. I usually run in sport plus and leave the PSM on.

Interestingly, PTV and electronic LSD is not present (and not available at all, even as an option) on the base 992 Carrera (385 Hp). I read some Porsche development engineer saying that they felt the PTV / LSD is not needed on the base RWD Carrera and the car feels more "lively" without it. On the base 992 Carrera 4 the PTV is not standard either, but available as an option. Starting from 992 Carrera S and upwards, the PTV is standard equipment - so no way around it. Same thing on the new 992 GT3, too. That being said, apart from the brutal brake pad wear if the car is used often in borderline cornering situations, the PTV+ (same as rear-axle steering, if specced) is quite a brilliant and useful system. As in ... it makes You feel a better driver than You actually are :)
