From what I can tell (online photos) the EM2 rear hub (drum) and rsx rear (disc) are the same, redrilling drums would be easy and in my case, preferred. Anyone know if this will worked? I searched and for obvious reasons its all about the disc.

 

What I'm understanding is that you'd like to put RSX 5 lug hubs inside your civic's drums. You want to change nothing but the hubs. yes?

theoretically, it should work if you're saying the hubs are the same.

But what will you do with the extra holes in the drum that may not be sealed off? Do your wheels have flat hubs that may seal them off? You're still going to get water in there.

I have to ask...why not just buy the disc conversion?

 

Yes that is what I want to do, but besides the obvious lug count, I don't know for sure if they are the same, they seem the same from online catalogue pics but I don't know for sure...... I would weld the unused holes closed and make it look like it came that way... The reason for wanting 5 lug has to do with the wheels I want and since I really don't need the extra braking power, I thought it would be different (and lighter) to stay drum.
