i have a95 dx civic with rear disc conversion. i called up the honda dealer and talked to them. they told me it is not needed at all to do a MC change. It uses the same one, he told me the only thing needed was the rear brake set up and thats it. anything else id be wasting my money. i put them in they work great. he said it depended on alot of different things, if you just call them up and give them all the model specs and such. they will tell you what needed.
