Lets see lack of brake fad, weight loss, Better stopping power. If you have to buy drums, hardware and shoes you are getting closer to the cost of Wilwoods. If rear drums were so good they would be still using them.
Big rigs still use drums. They haul 80,000 lbs so you think they use drums for nostalgia's sake?
Rear disc brakes in new cars is a "Keeping up with the Joneses" issue. One company installs them, brags about it even though it made no difference...the public buys into the safety claims and soon every company abandons rear drums.
In extreme conditions, the discs will fade less and weigh less. In the overwhelming majority of street driving, drums do the job well for less money.
I did a rear disc swap into my 70 Charger in 2006, merely because seeing 10" drums through my big wheels looked cheesy. The discs looked better but performed no different.
