New front rotors for 997.2 GT3
 
Spent some quality time with bsavino's 997.2 GT3 yesterday replacing the stock front rotors with AP Racing slotted disks.

The OEM rotors had 6100 hard miles on them including multiple track day. Some serious cracks were starting to show.

Red center nubs (what the heck are these called?) transferred over to the new rotor.

We had to get new screws that hold the rotor to the hub carrier because the OEM screws are a completely different design and didn't fit the countersunk holes on the new rotor.

Did you happen to check weight difference between new and stock rotors?

I was under the impression that Porsche recommends replacing those red "nubs" every time one changes the rotors. So it's not really necessary? Looking at the pic from Suncoast, I guess it's because those fasteners have some green loctite on them?

My Porsche tech did not replace them either, he is a GT3 specialist and told me there wasn't a reason if all torque to specs.

I just purchased a new set of Girodisc rotors for my 2011 GT3 and they came with new hardware to replace the Red Nubs or whatever their called.

I change the rotors out at the track (MMP) on Sunday morning along with new Pagid pads, took about 35 minutes to change out rotors and pads.

Stock size pads with AP ? . ? Different pads with Giro Discs I believe.

We kept the stock sized Pagid Black front pads for the AP Racing rotors. The outer pad on the passenger side was worn a bit more on the leading edge so we ended up flipping the pad. All the other pads were wearing evenly.

Sorry, didn't weigh the rotors to compare with stock.
