1992-1993 Civics ALL have smaller rotors than the Integra - even the Si hatch and EX coupes in 1993.

1994-1995 EX and Si have same size rotors,the calipers seem to be smaller on the Civics.

With that said, here is what MOST people do to upgrade their brakes to Integra specs - all of the following are not ABSOLUTES, but they make it much easier:

Get the entire front spindles from any 1994-2001 Integra. This should include the spindles, calipers, hangers, rotors, lines, and dust shields.

Simply unbolt the upper and lower balljoints, and the ball joint that connects to the outer tie rod ends, disconnect the lines and swap the spindles. Would be a good idea to have badly rusted rotors turned or replaced, and throw in new brake pads too if possible.

For the rears, try to get the entire rear trailing arms assemblies with the parking brake cables too. Then just swap the entire traling arms and you're pretty much done.

1994-2001 GS-R, LS, RS, any Integra brake booster. This bolts into any 1992-1995 civic.

You MUST have an Integra booster in order to run an Integra master cylinder! Although the lines fit perfectly on the Intgegra RS mastercylinder, no Integra master cylinder will bolt up to the CIVIC brake booster. Get the Integra booster and you will have to run an Integra master cylinder too.

Integra RS master cylinder. The base model RS Integra had NO ABS so the lines match up PERFECT with any non-abs Civic

The Integra master cylinder is a 15/16th whgile the Civic non-abs uses a smaller 13/16th master cylinder.

Finally, add the GS-R, LS, RS, etc. proportion valve and you will have completed the package. 1992-1993 Civics will require you to change JUST the bracket over - use the Teg prop valve with the Civic bracket. 1994-1995 Civics can use the Integra bracket.
