I am wanting to change the disc's and rotors on my em2 and was wondering sizes of what's allowable and what i can get the rear disc's from. .. i have the crappy drums in the back and i think disc's would look a billion times cleaner. . .so dimensions or actual parts that work will be greatly appreciated

 

Check the FAQ's about rear disk. The EP3 will fit nice. You are going to need the E brake lines as well.

 

here you go man i was just looking at that thread
