I have a 93 civic si.. non abs
As we all know they are small calipers and rotors 9.5


I have the 95 ex coupe fronts I haven't put on yet and gsr rears.. and new rotors.. 10.3 front and 02 03 si rears 4x100 10.2

I know the type r rears are the same size 10.2 but 5 lug.

If i got some type r calipers they bolt up to the gsr set or nah if so any fabrication needed

 

You want to have 10.3 with 4x100 on rears, right?
Search for ek4 rear brakes, thats what i did recently..

 

There is a sticky at the parent of this forum that covers this.
