These brackets are for the regular base model calipers. The rotor diameter is 10.865
I have never tried the brackets with the 11.25 rotors, but if the math is correct there should be a minor change by moving the mounting holes out .1925 inch from the base model brackets.
The cobra calipers are a bit harder to find in any salvage yard for the core charges. I believe i was quoted for the base model calipers a $90 core charge for a $120 caliper.
