My new-to-me 2007 GT3 has (I think) rotors that are not stock - does anyone recognise them? They are 2-piece, aluminum hat, about 350mm. The rears have no parking brake surface. The only markings I can find are on the hat, a big, block print "WR".

Next question - the rear caliper bolts are M12, 1.5 inches threaded, 95mm shank length. Wherever I see caliper bolts discussed on-line, they are 85mm. Does anyone know the part number for the 95mm use-once bolts? Are these standard on all GT3's (so my dealer has them) or are they "special"? Thanks!

 

That's some impressive pad transfer stamped on the rear!
The glazing on the fronts is a bit ordinary too.

Looks like DeMans.

Nope, the DeMans are one piece - plus, I just got a note from Craig - his guess is AP....

 

The good folks at Sunset Imports say the 95mm length is standard, and are sending me a box full.....

 

Those are Wrightwood....available thru most Porsche shops, if yours can't get them feel free to contact me.
