I am running the turbo 944 brakes and rotors from a 97 Porsche.
The spindles are C.B performance. To use the turbo rotors it is necessary to have them machined down so the caliper has enough "meat" to mount to. Their overall diameter is too much unless you have another mounting bracket made. I am running 23mm et FUCH 7x16 wheels at the front with spacers. The low et means the big turbo calipers would otherwise hit the inside of my wheels. I will try to post some photos soon.
