AHH.... but for rear drums, it wouldn't be possible for bolt to protrude "into" the drum to hold the adapter on. And actually, I don't know if there is enough clearance for that on Discs either. Gotta go look.
Back to the thickness issue to cover the factory studs.
there appears to be a little less than half an inch of clearance between where the caliper would be with brand new brake pads, and the back of the hub where the wheel stud seats. From what I could measure with my calipers, I have .475" to work with
Zefy, unfortunately those bolts would not be rated to do that. Considering the threads are in the brake rotor, and if one were to purchase cheapo-baseline rotors I wouldent want to recommend using those threads to hold on the wheel. Also drums in the back dont have the same story.
Basically the idea I am trying to accomplish is a "bolt on" product. Where one may purchase the product, follow the instructions, install them and drive away. Without having to disable the vehicle to ship parts, etc... waiting for the parts to come back...
