i was wondering what are the biggest brake rotors i can put on my 93 civic hb si without moving or upgrading the calipers?

 

your stock rotor size is fine

 

what if he wants them you shouldnt tell people what they want its their choice. Most big rotors will fit without upgrading calipers you just have to get at least an 17in rim. Oh and my 99si has aem big brake rotors all the way around. Yeah it slows the car down quarter mile time on the technical side not that much unless your car is slow, but hey its still fast and i like to stop.

 

You cannot run a larger disc withour relocating the calipers. Any decent kit should come with the brackets to relocate the calipers though.
