As we all know, the front brakes do most of the work, so it's easy to see why MaSnaka didn't see that much difference when replacing the rear drums with Wilwoods. I don't know about his CR, but my West Coast has 11" drums from a 1978 Thunderbird, and most of the other donor cars are probably in the same size and weight class. For a '78 T-Bird the drum brakes helping stop a car that weighed ~4200 lbs., quite a bit more than my WC Cobra, so they're pretty good stoppers already, though clearly not up to track duty mostly because of their lower ability to shed heat.
