Besides OEM and various 2-piece rotor offerings, are there any economical rear rotor options for the GT4 (ie Centric or DBA, etc)

There was a rumor floating a while back that the rotors from a Turbo might fit. But nobody has reported on that. You could be the first.

Budget option is leaving the oem rear rotors on and never looking back. My oem rear rotors still look brand new after almost 30 track days

I can feel a pretty prominent lip on the outer edge of the rotor, which leads me to believe that the rotor is at or past minimum thickness. I will take a caliper to it when I get take wheels off for cleaning this weekend.

check first. What pads are you using?

I've got 60 days on the rear rotors AP of my GT3 and they still look new as well. I'm not kidding. That is why I decided to just OEM on the rear of my GT4

the girodisc rear 380mm rotor is the same part number for both 991.1 Turbo (steel brake) and the 981 GT4

as per Mike @ Girodisc.

the oem part should therefore be also compatible...

i will try it.
