Did you ever find an under tray? I was cleaning my attic today and i have three, 1 for a 964, I for a 993 and 1 for a 993tt. All in excellent shape as they were taken off pretty close to delivery.

I'm looking for one too. I'll PM the people with them as there seems to be three available in the last few posts of this thread and the original poster is just looking for one.

Sorry for the dead thread revival, but does anyone else have one for sale?

Maybe on the newer 911, but on the older Porsches, these were originally put on to reduce motor noise on the street cars. Otherwise they would have standard on the 993 Supercups. I owned two, and there was no rear tray on either.

Respectfully I don't buy the engine noise thing. They don't make any difference to engine noise- I just took mine off.

However the underside of these cars is completely flat- with an engine tray- that's not coincidence in my eyes- only my personal opinion.

No worries on my end. Years ago, Porsche came out and said it was a noise thing, it was not me. In any case, I have taken them off of every 964 and 993 I have owned. That is why I have two for sale.

Weren't they an option for the 993 cup models? You had to order the;
"Unterboden 3 geteit "Le Mans" GT 95 Sonderzubehor" Which had the undertrays that completely covered the bottom of the car front-to-back (part numbers below) and the mounting hardware to go along.

993.504.131.90.R - front undertray
993.504.133.90.R - middle undertray
993.504.135.90.R - rear undertray

I am not saying there wasn't a part # for the rear under tray as the 993 cups still had the mounting points for it. But.....those trays would keep in the heat, which would be terrible for a sprint race car. I would agree the the front two sections were important, but not the rear. Maybe on the a version that had a higher gearing for speed at LeMans would be used for aero. I know the GT1 Porsche used it. I still have my owners/parts manual for the Cups. I will see if I can find the footnotes on that particular piece and the Porsche Motorsports recommendations for its use.
