I bought a pair of front drilled and slotted rotors for my 91 crx. I was going to use them and the stock drum setup for the rear. Today I bought a complete rear setup from a 95' integra ls. Now, I want to upgrade the fronts as well and was wondering if I could use the new rotors that I was going to put in the front on my rear integra brakes and upgrade the fronts with the fastbrakes kit.

 

no the rear arent vented so the caliper width would be off

 

yeah, your right I didn't think about that they are thinner; but, they are a simular diameter though, right?
