Rear Rotors for 6GT3
 

I was able to get front non-crossdrilled rotors from TomChan, now I'd like to find no cross drilled rotors for the rear. Any leads on a OEM like rotor without the stupid cross drilled holes?

I believe stoptech makes a solid but slotted rotor for your car, not sure of the part#. Here is Suncoast's webpage showing all of the other models that use that part# as a cross reference. https://www.suncoastparts.com/product//9Z79RFR.html
It may be easier to find one by looking via another model, like the 09-12 Carrera. The actual Porsche part# is 99635240502.

OG racing has the PFC rotors, so give Mark a call. Also Frozen Rotors carries some slotted/solid for the 996/GT3.

I just installed a set of Centric slotted rotors on the back of my 6GT3 yesterday. They cross-reference with Panamera rears.
Part #'s are 226.37039 and 226.37040. They were $43/ea shipped from Amazon.

That is great info about the cross reference. Does anyone know what the fronts cross reference with?

Bob, this is what was on mine when I bought last year, have since gone to PFC on fronts. Still have indicated rears, show little wear. May be able to use as reference.

Fronts are from a 2004-2006 Cayenne S
Left F: 95535140151
Right F: 95535140251

Rears are from a 997 Turbo:
Left R: 99735240502
Right R: 99735240602

For the Cayenne front rotors- there are different diameters available. The 350mm version is a match for GT3 cast iron rotors.

Yes, the GT3 and Cayenne's they are a match in 350mm. Except, I believe the diameter of the wheel lug holes in the Cayenne version are just slightly larger, like by 0.5mm. I don't think this would have an impact on drivability or safety. Maybe one of the Dorki engineers could chime in that.
