while cooler/more air is 'always' better, factory 6GT2 ducting and disc sizes are more than sufficient, add pads and fluid and enjoy

 

Thanks for the pics guys! I'd tried searching online with no luck.

 

are the GT2 front lower ducts the same as the 996 cup front ducts? They look really similar if they are not the same part.

 

IIRC, the 2001, 2002 GT2 parts are the same number as Cup, the 2003+ GT2 are very similar but now one piece moulding vs the riveted construction

 

These are the part numbersfor the front brake ducts:

996 341 183 90 and 996 341 184 90: 2001 996 GT3 Cup.

996 341 117 90 and 996 341 118 90: 2004 996 GT3 Cup, 996 GT2 MY 2001/2002 and 996 STREET GT3 MY 2002.

996 341 117 92 and 996 341 118 92: 2004 996 STREET GT3RS.

996 341 117 91 and 996 341 118 91: 2003/2004 GT2 and STREET 2004 GT3.
