I suppose there is a fair bit of adaptations for it to work, but someone must have done this? The brake balance seems to be good for this setup as well. And they aren't that enourmous either, which is a good thing. I'm using 17" wheels though, so I could go slightly bigger in theory, I believe.
The reason I'm asking for that setup is because it might be cheaper than 930 setup, but still used for a turbo car. You see, in Norway, a big part of getting your car approved with more horsepower than stock, is to prove that you also have upgraded the brakes to match the performance. So I need to fit brakes that are from a high horsepower application originally. 964 and 993 C2/C4 brakes might not be sufficient to meet this "requirement" from the controller.
Anyone? |
964t brakes to a 911 is fairly easy, the brake bias gets moved more front than I prefer but not as much w/ as much negative side effects as w/ some others
In front you use 993 2 piece rotors, these are 322x32mm. remove the hats and discard them, replace w/ flat aluminum hats. The calipers will need an adaptor to bolt to the 911 strut. Both adaptor and hats are available form places like VCI.
In back use a 309x28mm 930 rear rotor from a '78-89 930. The calipers will need to be modified by filling the existing mounting holes and redrilling the holes to fit the 911s 3" OC mounts, Here's a pic of the filled and redrilled rears
finally, use a 930 '78-89 m/c
I would caution against any of the 996 calipers especially 996tt as bias gets moved way forward, most owners end up having to also use a racing twin master set up
