I wouldn't worry about the forward panels as the 996 ones are basically flat anyway. I didn't see a benefit to messing with those. I'm running the rear 997 panels. The center attachment points are the same but the ends are different. For a proper fit, you need to cut the ends off the 996 and 997 panels and then rivet the 996 ends onto the 997 panel. Not terribly difficult but time consuming. Next time I have the panel off I will take a picture of it. The 997 panel has naca ducts which channel air to the air guided that clip in the rear thrust arms and divert air to the rear brake calipers. The rear 997 triangular cover is a straight bolt on.

Yes, the last two panels, the triangle and the one prior to it. They make two versions of that one, the TT and the GT3 one. They both have nada duct inlets for caliper cooling and the TT version also has naca inlets on both sides of the gearbox (to provide cooling air to the gearbox). The GT3 version does not have these since it has a gearbox cooler in that location. The picture you have above is of the GT3 version and that is the one I'm using. If you don't have a gearbox cooler, use the TT version. I'll get part numbers for you later. They are in PET. I did not replace any of the forward panels.

Did you trim the 996TT fender liners for the ducting or is that a 997TT liner?

Hi guys,
i did some research.
The triangle part Nr.: 997 504 429 01 (turbo I480)
The panel before the triangle one:
997 504 029 00 (turbo I480)
997 504 629 03 (turbo I249)
997 504 629 92 (GT2 I480)
Which of these 3 to buy?

I have heard of a different version to make the rectangular 997 TT panel fit. Instead of cuttin both panels, u can drill two 2mm holes in the side skirts and mount the 997TT panel just there with some ordinary hex screws on both sides.

I really do not know what went wrong this spring, but they've been there at speeds of 315 kph without a problem, but now at Autobahn A1 north of Lübeck they departed. There was a very sharp vertical bump (not common on those roads) , but still...
Luckily there was nobody right behind me.
