Yessir, Panamera Turbo rear fits our rear @350mm.
Looks like Cayenne front part numbers

Any issues with parking brake in the rear with the Panamera turbo rotors?

Cayenne front part number is correct as well, right?

993GT

I have not run the Pana rears myself yet, but should work per spec...maybe LIS can confirm.
Yes on Cayenne bits, I run same from ATE on my GT2.

Thanks, hesitant to try the PanaTT rears if no one has used them before. I guess 45 bucks a piece, not a big gamble but would hate to lose time shipping back and forth and having the car apart.

993GT

believe user LIS ^ said he is using them...maybe I'll bug my favourite dealer to save me a couple used/worn-out take-offs to verify/test fit...

LIS

I can confirm that the standard 330mm Panamera rears are direct bolt-in replacements on my 996GT3. I've been using them for about 6 months, including 7 track days with no issues at all.

I don't have any experience with the Panamera TT rear rotors, but the part #s do cross reference with the rears on the 997GT3.

CosmosMpower

Yep the rear part number says it fits 07 GT3 on Amazon but oddly enough the front part #'s say it doesn't fit.

LIS

That's because the front part # is for a Cayenne, and it's slightly different from the GT3 part but still fits fine. The only real difference is with the hole for the retaining screw. On the GT3 rotor the hole is small and tapered, for a recessed phillips head screw. On the Cayenne rotor the hole is much larger, not sure exactly what's used instead of a screw.

In any case, if you use the Cayenne part you can still use the phillips screw to hold the rotor in place during installation. Keep in mind that the lug bolts are what actually keep things together once everything is back together.

Just ordered the part numbers I posted on page 15 from amazon. Will report back if they fit my 997.1 GT3 with red caliper steel brakes (350/350).

CosmosMpower

Got the first part of my rotor order today, Centric part # 125.33091 one of the 350MM fronts. It was a blank rotor with no slots machined in. Did they send me the correct rotor?

993GT

correct, 'stock' Cayenne discs are not drilled/slotted/etc.
The ATE discs for Cayenne do have the elliptical slotted pattern.

CosmosMpower

From the pics on Amazon the centric rears for Pana TT have slots. Will be interesting to have blank fronts and slotted rears.

993GT

Yes they should, I am interested if they do a hashed slot like factory or more conventional 'full' slot...
It's all good, aside from the occasion questions about them, I have ATE slotted on front and factory 7GT3 drilled discs in the back

CosmosMpower

Got the rotors put on. Rears are perfect, fronts seem a bit "off". There's an extra hole about the size of a lug nut hole that does not line up with anything.

Also the pad doesn't seem to go quite to the center of the rotor. Is this normal?

Also I sheared off the 10mm bolt for the hard brake line bracket, is that important when everything is put back together?

^^^that swept area looks fairly normal to me.
