I still prefer 4 wheel discs. I also tend to change to 4 wheel discs whenever possible just to avoid the torture of servicing drums. I can't think of a single vehicle that still has drum brakes. But what is worse is the 4 wheel disc set-ups that use a small drum brake inside the rear hat for a parking brake. Hard to service and a piss poor parking brake too. In that regard the second gen Firebird rear discs are the best to use.
