Notice any change in the car's handling when they departed? Or were you too busy ****ting yourself?

 

I guess its the age of the underpanels, that make them break or getting lose.
The 997TT underpanels share the same secure points like the 996 TT, except for 2 spots.

 

Probably better off just using a flat sheet of alumalite or aluminum and riveting to the stock panels. The df difference is huge with a real flat bottom. This is just going back to the rear axle.

 

Without a tranny cooler, thats not a good idea. With the RUF Front, GT2 decklid and with 1 degree chassis angle there will be enough df. Of course not that much like the 991 GT3 RS or 991.2 GT3 but hey...these cars are expensive and can be driven fast from a grandma. :-)

 

If people are looking at adding 997 TT panels, might as well do it right the first time. The vents to the transmission tunnel can also be installed on a continuous flat bottom. But even those are not needed unless you're endurance racing. I'm simply suggesting a method that increases DF in a big way and isnt much different from what is being discussed here.

 

Of course there are many ways to do it.
All good heavychevy. Peace.

 

Have you guys installed the new panels (the ones that don't require modifications)?

Everything go smooth? Easy to do with a lift?

 

Does anyone have the full list of part numbers for all 4 panels needed? We have the two PN for the triangle, what about the two rear side panels?

 

My mechanic said he needed to do some minor cutting and drilling to secure the Panels with screws.
Wasnt that complicated he said.

 

Do I have these two other PN's correct?

Center Left Belly Pan
99750434303

Center Right Belly Pan
99750434403

As already stated previously:

The triangle: 997 504 429 01 (turbo I480)

The panel before the triangle:
997 504 029 00 (turbo I480)

 

...and then these part numbers are what?




These ducts seem to be separate parts from these two underbody panels, what P/N's?

 

There you go...
997 575 183 00
997 575 184 00

 

How much of the panels are you just screwing up into the chassis?

 

The first two pics are of 996GT2 rear brake ducts. They clip on to your LCAs. The metal brackets pictured are the correct ones. A bit of a Chinese puzzle to orient them properly but they clip on. Search the internet for pics. I used to run these.

The last two pics are front 6GT2/Cup brake ducts. The upper part is the OEM 996TT duct which has the larger scoop riveted on. The attach just like the TT ducts.

 

Not sure what ducts you have in mind Steve. The 3 main ducts in my bumper are RUF. The GT2 bumper has very similar ones. There is no duct attached to the front GT2 liners. Air is routed from the side radiators through the inner opening of the front GT2 liner then via upper air guides (which clip on to the coolant pipes) to cool the front brakes. The 6GT2/3 versions will not work on your car since you have the TT hard coolant pipes. Honestly, unless you are running long sessions on a road course, the upper guides are not necessary for street use especially if you have the large lower ducts. I use the 7GT3 upper air guides which I have modified to clear my 10" front wheels. The 6GT2 guides would not clear and are hard plastic so not easy to heat and mold.
