GT3 Rear Brake Duct part numbers?
 

Does anyone have the gt3 rear brake duct part #s. I already have the front brake ducts but I can't seem to find the part numbers for the rear brake ducts. I have pics of what they look like. In the image the fronts are the large ones and the rears are the smaller ones.

I'd get in touch with the folks at Suncoast Porsche. Pelican, our new hosts, maybe able to help as well.
Having said that, and this being a Boxster forum, assuming you've got a Boxster, I don't think those will fit. The GT3's rear suspension is way different from the 986/987 platform.

Yep, very different animals in the rear. There are two under-body spoilers that attach the the lower shear plate (triangular thingie) which moves air to the rear brakes and engine compartment. If you have those the rear brakes should never overheat.
