See photo below, which is the underside of a 997 GT3RS. I notice there's a plastic undertray just upstream of the suspension crossmember, I've outlined it in green. Do model year 2004 996 GT3's also come with this undertray? If so I'm missing mine.

 

Hmmm...from this post it looks like I'm not missing anything.

Maybe it's just a 997 thing.

 

mine does NOT have it. 04 GT3

 

Correct, the 6-3 does not have that piece. I've compare pics of both my 6 and 7 and can confirm this.

 

Don't have it on mine. I have tow eyes bolted where that liner bolts too. Definitely not there. Mike

 

I don't have one either but that's been well established. Instead I wanted to comment that I also don't have 996flt6's Avitar. Way cool man.

 

My 05 gt-2 goes not have the under tray either! FYI

What he said. Another subtle difference between the 6 and the 7
