Are the civic SI and 94-01 GSR rear rotors the same size? Or are the GSR's a little bigger?

Also when putting rear disc on my eg will I need the rear flexable brake lines from an SI or a GSR, or will the drum lines work?

Thanks in advance for any answers, I'm just trying to get everything I need before I go out in michigan weather and tear my car apart.

 

si and gsr are same sizes. and yes u need rear soft lines off of whatever car you are getting it from.

 

Thank you.

 

Yes, you cant use drum brake lines. Must use disk brake lines.

 

also, you can use the stock UCA and LCA if they dont pry off... i did haha

 

ls from 94 + are the same set up also. yeah rear flexible lines.
