Jason,
Unfortunetly, the calipers are not interchangeable between the .810" and 1.250" rotors. The calipers for the .810" rotors are .220" narrower from the mounting lug which is where you gain your clearance to the ridge in the corner of the front wheel. So, you can not just change rotors to bolt on different sets of wheels.

If you go to Wilwood's website and download the catalog you will see the diagrams and dimensions for the Superlight calipers on pages 30 & 31.

Specs for the SL4R Radial mount calipers and brackets are available on pages 22 & 23.

Feel free to PM me if you'd like more info.
