Right now I have a 1999 hatchback and the left side of my car hit the gaurd rail and I need to replace the drivers front rotor, caliper, and caliper braket......would it be worth it since I found a good deal on 1995 GSR front brakes to upgrade to those?

-Are the brakes big, smaller, or same size as my stock civic ones?

-Will I run into any problems or need any extra parts?

-what all will I need to do the swap?
-brake caliper
-caliper bracket
-rotors
-pads
(is this it?)

Should there be anything else i should replace as well? I already have stianless steel brake lines (obviously I should use new fluid as well)

Any help would be greatly appreciated! Thanks!
