Title: camaro two piece rotors
Post by: onebad34 on April 27, 2008, 12:59:11 AM

I read the articles on the two piece rotors posted earlier. I was lucky enough to pick up two sets at spring carlisle this weekend.  Question, is there a difference between the 67's and the ones used on the 68-69 cars.  I was told that the 67's had holes drilled in the hat area to cool the bearings.  Are they interchangable and what do I need for on my 67 restoration project.  thanks Pete

I have the original ones on my car and picked up a set for spairs.  What holes are you talking about for cooling bearings?
I can't see putting holes were the bearings are for grease would come out.  I also don't think 69 rotors were the same for the single piston calipers.

the outer edge of the hub has a cut back on it to clear the dual calipers,

I looked at the rotors on my "68" which I believe are original and only the drivers side has the holes, three of them. Also a few years ago I picked up complete hub assemblies off of another "68" for spare parts, again only the drivers side has the holes except only two. I don't know what the holes are for, possibly to balance the rotors. Hope this helps, RonM.

thanks for the input. the two sets we picked up at carlisle, only two has the three holes in them. someone at carlisle said that was for cooling, I don't think so.  I would believe for balancing before I would believe cooling.  thanks.  Pete

The holes are for balance .The vents between the rotor faces are for cooling .Steve.
