Rotor difference in ST & GT Options

[celicaridinghot]

I have been shopping around for rotors and I come up on nice rotors but they are all specified for the gt is there really a difference if they are the same year in st and GT for rotors. for example could I buy ones specified gor gt and use them on my st?

I'd have expected you to need the brakets too tbh, as the st discs are 255mm and the gt are 275mm, however, if you measure the gap between the edge of your current disc and the inside gap of the bracket then you'd know if theres 20mm gap then you can fit them in.
