Best rear disc kit for 1970 Beetle.

[Cancerman]

I was wondering what is the best performing rear disc brake conversion kit? I've got a 1970 Beetle pan under my Kelmark, using an EA81 Suby. Need to off the rear drums. Already have a front kit with Wilwood calipers, and 2 inch dropped spindles, narrowed beam. Any input would be appreciated. Thanks, Mike
