Above is the PSCB brakes after less than 3,000mi of highway driving and 3-4 track days. The brake pad wear indicator is on. My plan was to replace the pads, only to find out Porsche made these PSCB pads proprietary and there is no aftermarket alternative.

Instead of replacing brake pads every 3,000mi, I want to save some time down the road and just get rid of the PSCB. Can I simply unbolt the PSCB rotor and put on OEM cast iron rotor instead?

I want to reuse the PSCB calipers as they seem to be the same as the base 6 piston front /4 piston rear calipers except the paint color.

reach out to the braking vendors. Race Technologies (Brembo), Giro, PFC, etc. See what options they have for fitment. I could swear these are larger than the standard rotors.
I think this is it:
cast: 360mm
PSCB: 410mm
PCCB: 420mm

So you'd need a retrofit rotor + pads of the proper diameter, annulus, and offset.

Even if you found an after market solution I don’t think they’ll be much better because you’re dealing with a very heavy car. Not only will brakes wear out quicker I wouldn’t be surprised if replacing suspension parts occur more frequently as well.

you are actually right

At least the rotors made it through 3-4 track days. I have no experience with tracking my Taycan but from what I have read, brake pads and tires wear much quicker than on lighter cars. Tracking an EV is an expensive proposition due to the weight.

Don't take a Taycan to the track unless you have gobs of money and don't want to drive an actual sports or race car. The car is not made for it- no matter what Panorama magazine or their bull**** writers or even Porsche might say. Most clubs won't even allow it- we don't need a 5,000 pound battery catching fire or crushing a 912, light weight 911 or 914. Much less a 964 or 993.

It's an extremely heavy four door sedan. Take your friends to dinner instead.

FUD.

Taycan is not a track car but it's perfectly capable on track and fun too.

You should try one, and yeah I have 3 generations of 911 that have all been on track, a couple of them a lot. All are fun.

I've seen way more gas cars catch fire than EV, which are becoming quite common at track days out here.

Yes, the ability to deal with a lithium fire is a concern for tracks that don't / haven't invested in the training and equipment. They need to get with it.

Wow. God forbid someone wants to track a car that you deem less than "an actual sports or race car".

3-4 track days and you're surprised the pads are shot? And you didn't research the exorbitant cost before doing that?

George from MD

Neither I nor God are forbidding it but lots of clubs and events do. For the same reason they don't allow Cayennes or other heavy vehicles- safety.

And FWIW I taught DE events for twenty plus years and never once saw a car catch fire. Plenty of incidents, a few deaths but never a fire. I think Taycans are great cars -I've driven them and it's the only electric car I'd even consider. But I wouldn't take it to the track. It's a very heavy sedan that's made for cruising. But maybe that's just me. YMMV.

Other than the normal high brake pad wear, any other issues with tracking the Taycan? Have you replaced the brake fluid? How well do the stock pads handle the heat? Thanks

The PSCB pads and rotors will last VERY long if you don't track the car. I have PSCBs on my Cayenne Turbo, which is also very heavy, and it's driven mostly in mountains at high speeds, so lots of brake wear, and it's still on original pads and rotors after 75K miles. Taycan, with its regenerative braking, should have them last even longer. But because of the composition of the rotors, the pads are not as temperature-robust as racing pads, so they practically melt when overheated. It looks like that's what happened here - the stuff on the rotor surface looks like melted pad residue. It should go away over time after new pads are installed.

If you must track it, managing brake temps should be possible, but it can get annoying or limiting. So aftermarket may be a good idea - try Essex parts (sponsor on this forum) - they have pads, rotors and even entire brake kits for various Porsches. But still, this car is just too heavy for serious track driving, and not just because its electric but because it's a big and heavy car - an M5 would be in the same boat.

Has anyone tracked the standard cast brakes? Changed pads?

George from MD hates EVs - don't let him tell you otherwise. The Taycan is a perfectly capable track car as evidenced by the Turbo GT's 7:07s time at Nurburgring; the Boxster and Cayman EVs will only further develop the capability.
