Wilwood makes a Pantera specific hat for outboard mounted rotors. I don't recall the part # but the description is "Pantera Competition" hat. It's much deeper than the regular Pantera hat so you don't need to re-mount your calipers for outboard mounted rotors. I'm sure we have Dennis Quella to thank for Wilwood manufacturing this particular hat.
IPSCO makes a front hub that's designed for outboard rotor mounting. It has the mounting surface recessed 1/4", so outboard mounted rotors don't alter the offset of your front wheels.
Also, if you're going to go the effort of converting to outboard mounted rotors, it's the perfect time to switch to stronger, cheaper 1/2"-20 lugs.
