instant-G's has an adapter kit with special machined 996 hubs, wheel bearings, seals and caps, and two adapters, hardware. It uses stock 996 330x34mm (13 x 1.34") ventilated rotors which is good from the wear replacement aspect. FYI, min wheel size is 17".
Chris fabbed his own brackets to fit 996TT calipers and turned down 930 rotors to 12.45" to fit in 16" HRE modular wheels.
No response from VCI yet.
Felix, The 34mm wide rotor is for the 996TT and 993TT brakes. BoxS/996 calipers are *NOT* 996TT calipers. The BoxS/996 use a 28mm rotor. Which caliper do you have?
AFAIK, those 993tt/996tt kits use the 993tt rotor since it will fit over an early 911 hub easily w/ a custom hat. Chris turned down larger rotors close to that of a 930 so they will fit under his wheels (right thickness, but 930s are too small to start w/ - I think only 12". That why he haad to start w/ the larger OD rotor).
You cant easily put 996 rotors on a 911 because the 996 slip over the hub, the 911 bolt behind the hub. Even if you redrilled the 996 bolt holes to the right size, the hat is about 15mm deeper - the rotor will likely hit the strut or leave zero room for the caliper between it and the strut. It looks possibe to turn down the OD of a 911 hub to fit the 996 rotor (about 160mm ID), but its going to take ALOT of meat off the 911 hub. Strength might be an issue. I *THINK* timmons machines a 951 hub for some of his kits but that has been just speculation on the boards.
FWIW, I have 996 hubs, brakes, rotors, and 911/930 hubs in the garage to try and figure all this stuff out. It doesn't look really easy to fit 996 brakes to a 911/914 (which is why I bought a 993 backup set;) You're best bet is to find some aftermarket brembo/alcon rotor thats 28mm thick and make a custom hat. Then it'll be a no brainer.
Edit: looking at the timmons kit its definately a 996 part (well, technically a 996tt part). Maybe the 996tt rotor has a larger ID and doesn't require turning so much material off the hub. *IF* you have 996tt calipers, if might not be a bad way to go (but why not just use 993tt rotors - darn near same size, lighter (w/ aluminum hat), no hub machining, and they are trick 2 peice bits?)
