When a Caliper issue caused one of my rotors to warp I found these from speedway fit perfect and a reasonable price made it less painful to replace as a set. The machining and finish seemed very good. I ordered a bearing kit for little more than just the seals cost locally. I couldn't find coated rotors so I also Painted what I could to slow down future rusting. With the 156 Pads installed I got great stopping power with no squeaks or vibration.

What is center hub diameter? Trying to fit aftermarket wheels to this rotor. Most wheel applications are for late model cars so a custom fit might be required. What is the center hub diameter to ensure this will fit inside the center bore on new wheels? Also, would a hub centering ring be required?

Does this particular rotor use the same bearings as a stock drum and hub set up or do I have to buy new bearings? My old bearings I just replaced about 6months ago I would like to reuse them.
