I have the 356 mm discs in 17" Team Dynamics Pro Race 1.2 wheels. But before this I used to have 17" TSW Hockenheims and those had much less space. The biggest I could go with those was 320 mm discs with the standard single pot calipers. So there can be huge differences between one 17" wheel and another 17" wheel. It really depends on what type of wheel you have.
