I chose to make the change to rear disc for a few different reasons.
The first reason was that I was going to have to spend $$ to rebuild my brakes anyway.
The second reason is that they do improve the controlled braking when you need to stop in an emergency without as much tendency to lock up.
Although I don't do road course racing I know that discs aren't supposed to build up heat and fail like drums.
I like the idea of simplifying brake service in the future. - No longer having to put up with broken springs, the rusty crusty small parts, etc...
I also like the looks of disc brakes, - so I figured there was a sort of 'cool factor' also.
If I was doing a true restoration I would stick with drum brakes of course.
