Mine are very light weight indeed, German made carrera 3.0 rs shape
The rear one is a bit open up for better heat transfer,the front is good for a big central
oil cooler, it doesn't need to modify the front of the car to maximize air flow through
the cooler
This is the very same set up the Frankfurt '73 turbo prototype before G model concertina being introduced ,so I think is something the factory actually designed and tested for the wide body 911 platform
