Anyone tried replacing stock steel rotors with Brembo Type 3? Seems like a better option for track days.

I replaced the pccb rotors on my spyder with brembo type 3. For how much they cost, I was disappointed with how long they lasted. I'm going to guess that OEM rotors will last just as long and will be cheaper. I bedded the rotors per instructions when they were brand new, and they ended up lasting only 12 track days. In fact, oddly enough, the pfc08 pads (barely) outlasted the rotor. The rears still look new, though.

^^^so much cracking...I would expected that with drilled stock rotors...not these.

orthojoe

Yeah, they definitely crack. Gonna give RB a try next time. We'll see how long my second set of brembos last this time...

What's wrong with the OEM rotor?

MayorAdamWest

OEM is drilled.

I had Girodisc rotors on my 991S and they only lasted about 10 track days. RS29 front pads maybe 8.

Sooooo...? Seen drilled stand up to some abuse, that's for sure!

Seen OEMs that have been cryo treated (home made and aftermarket buy) last longer than those which haven't. Which ones did you see?

I have 13 track days on my rotors, with 4 or 5 on OEM pads and the rest R29. Porsche specs says rotors myst be replaced if cracks exceed 5 mm in length (used to be 7mm). Mine are about 7-9 mm but don't look too bad. Can anyone who knows tell me if this looks bad enough to replace? Looking at Joe's, they look pristine

You should absolutely replace them if a crack connects two of the drilled holes or if one reaches the edge of the rotor. As far as other cracks go it's more of a judgement call.

For me, these look like they are just getting started. For DE's should last for a while. If you are racing hard, then maybe not so long.

No easy one-size-fits-all answer for brake rotor and pad life. I for one am pretty hard on brakes and chew though them pretty quickly. My pad of choice on the 7.2 RS and my Cup is the Endless. Expensive, but well worth it. For a rotor on the RS I used the PFC slotted.

See my comment in prior post.

The quote above is flat out wrong. Assuming you are in the fastest DE group, assuming you're actually driving hard, there will be zero difference in consumable wear and tear. I've got years of experience in both DE and racing to back this up.

I caution anyone against Giro rotors. This is what happened to the last set I bought a couple of years back, after only a handful of track days...

Wowza! I'll be sticking with OEM, thank you.
