You may find a hat to do the job here and then select a Wilwood rotor to use with salvage calipers, if a salvage rotor with enough hat id and offset cannot be found:

Here is a diff that appears to be based on the vw transaxle:
http://www.transworks.biz/minidiff.htmlYou might use deep hat, slip on, salvage rotors and calipers, with the hats inboard and modify or purchase stub flanges. The problem is clearance to the starter and bell keep the rotor od down to about 6 or 7 inches. The axles could be taken apart to mount the rotor under the bolt heads for a larger rotor, but I think it would be damaging to the cv, as the brake torque and heat would be distorting the cv housing.
