PCCB wear on GT3 RS

[stujelly]

OK I hope this does not become one of those PCCB vs steel brake rotors debate but I am looking for some feedback from some others that like to drive their rs cars.

I just turned 3000 miles on my car, no lie I have 1000 miles of track time. not alot compared to some of you guys but alot for me in 6 months. California speedway, willow springs (big willow), and a few days at Buttonwillow. Total 9 days.

So I have heard horror stories over the cost of the PCCB rotors and that most people advise not to wear the pads below 50%.

So I took my car into the shop and it was determined, from measurements, that my fronts were 60% and the backs were 70%. I feel like I drive pretty aggressive on the track and yes I leave the TC on. Oh and no beveling. I will add pics when I get the car back. The mechanic said my rotors look brand new.

So here is the big question, I am replacing pads with new ones, OEM, at this point unless someone can recommend a better pad. If I just replace the pads before 50% how long can I expect, or how long have others experienced that their rotors will last? Can I expect 5 years with the stock PCCB rotors as long as I stay on top of pad wear?

If so then what is the big deal running the steel rotors?

I am told that replacing the PCCBs is a 12 to 14k proposition and I do want to avoid that.

a wise man once told me that if you get more than 20 hours of actual track time per year then pccb's are a very expensive option

also I believe there was a recent Porsche service bulletin that said that stock pads are the only pads reccomended for use by Porsche... that the p50 motorsport pads are too harsh

Switch to steel, brake feel is better and if your ceramics are in good vcondition you can sell for good money still

For some reason (not exactly sure) two RS this year at Sebring with ceramics got ice mode....who knows if the stars aligned or it was the brakes......I wont risk it

I concur.

Do tell, whats the secret??

[PJS]

The advice has spanned from tire sizing, moton set up, gearing, alignment etc

All stuff I would have figured out eventually on my own but if I can learn from others who have already done it, then that is all the better.

IMHO, that is the absolute best part of these forums.

If you intend to stick with the PCCB's then stick with the stock pad and just realize you're going to be changing pads more often. Keep an eye on the pad tapering even if you don't think you have a problem. You MUST inspect the pad wear by looking at the lower half of the pad regularly. Mine and every other PCCB track'd car I've seen has had tapered pad wear. Including at '10 GT3 that shared a garage with me at Mid Ohio this weekend. He's tracked his car a lot and came a fraction of an inch away from destroying a rotor due to severe tapering. There was a lot of pad looking at the top of the caliper and practically none on the bottom.

Words of wisdom. Must check the leading edges of the pads as bman notes.
