    I'm currently in a '95 Honda Civic EX Model that ran STS all 2016. I would like to convert my rear brakes to disc over drums. In the Si version of the 5th gen civic Disc brakes were standard. But my EX did not. Am I okay to swap over to disc brakes and remain in STS? Am I also okay with upgrading to SS lines?

    Below is the part of the STS rules concerning brakes, I have bolded the relevant sections:

    A. Non-standard brake rotors may be used provided they are of equal or
    larger dimensions (diameter and thickness) and made of ferrous mate- rial (e.g., iron). Thickness includes the individual plates of a vented rotor,
    as well as the overall dimension. The diameter for replacement rotors is
    measured at the minimum outside dimension. Aluminum rotor hats are
    allowed. Cars originally equipped with solid (non-vented) rotors may utilize
    vented rotors. Cross-drilled and/or slotted brake rotors may be fitted
    provided all such voids are within the disc area and comprise no more
    than 10% of that area. Brake calipers and mounting brackets may be re- placed provided they bolt to the standard locations and the number of pistons
    is equal to or greater than standard. A functioning emergency brake
    of the same type, operation, and actuation as OE must be present. Drum
    brakes may be replaced with disc brakes of a diameter equal to or greater
    than the inside diameter of the standard drum. Such conversions must
    be bolted, not welded, to the axle/trailing arm/upright and must include
    an integral, redundant emergency brake. Changes to backing plates/dust
    shields/brake lines to accommodate these changes are permitted but may
    serve no other purpose.


    B. Brake lines may be substituted with alternate DOT-approved flexible
    brake lines.
