Any views here on the cost savings of PSCB?

I'm sure the standard brakes will be perfectly good enough for my purposes, but wonder whether the extra cash spent on speccing PSCB might be won back through the claims that they last much longer than the standard offering?

I fear that not even the most sophisticated ’Man maths’ could justify £2k on PSCB on the basis of longer life!

+1. More likely to be justified in less hours spent cleaning brake dust off the wheels

Sounds like a challenge!!!

Just don’t get them damaged which they do easier than the standard

This is the carbon coated steel brakes right? How long do they actually last, does anyone have any idea on replacement cost?

They are coated in tungsten carbide. Porsche claim 90% less brake dust and pads last 30% longer. Not sure how those percentages work out.
Basically the discs wear less and don't rust and last considerably longer than basic steel ones.
I spoke with two Porsche technicians who raved about them.

Steel?

Caste iron

"The Porsche Surface Coated Brake (PSCB) combines a cast-iron brake disc with a ceramic coating. The brakes shine not just with white brake calipers. Other advantages include improved corrosion resistance of the brake discs, even during prolonged idle periods, and significantly reduced formation of brake dust. The result: the wheels and brake system stay clean for longer.

- Brake discs, internally vented
- Composite brake discs at front with aluminium brake calipers
- Disc diameters: 390mm at front and 356mm at rear
- 6-piston brake calipers at front and combination floating calipers at rear
- brake calipers in White"

cuurent extra cost on Macan S £2150.

i have not found any UK firm indication of actual replacement rotors and pads cost. it is reckoned they have 30 % more life. However, on Rennlist there is this old post that would indicate they do not pay for themselves:-

"I agree, the PCCB should last the life of the vehicle, where as the PSCB says 30% longer. Not sure if anyone has looked up the replacement price for PSCB, they are significantly more than you would think. Previous turbo steel brakes was about $1K for rotors and pads. For PSCB it is $6500. If you plan to own a turbo for 5 years or longer with average miles, you will definitely be replacing the brakes whereas the PCCB will still be good. To me worth the 4750 price to upgrade."
